| Abstract: The article presents results of experimental identification of MR (magnetorheological) damper model for an off-road vehicle. Original shock-absorbers of the vehicle were replaced by suspension MR dampers supplied by a dedicated measurement and control system. The vehicle includes several sensors which allow to observe electric currents controlling MR dampers, forces generated in the front vehicle suspension columns and other sensors which measure deflection of these suspension parts. The front part of the semi-active suspension was tested using laboratory setup with vibration mechanical exciters generating sinusoidally variable excitation at frequency equal to 12 Hz. MR dampers were directly controlled by peripheral electronic units generating different constant currents equal to 0, 0.11 and 0.37 A. As a result, evaluated force-velocity characteristics and analysis of MR damper behaviour in the target vehicle were carried out. Further steps of analysis included mathematical description of the selected MR damper using several types of MR damper models, i.e.: Bingham and hyperbolic tangent function models as well as their variants including first-order output dynamics. It was shown that the dynamic model based on hyperbolic tangent function offers the best fitness to the response of the actual MR damper with respect to the mean-squared error. |

| Modeling of Thermal Processes in a Microcontroller System with the Use of Hybrid, Fractional Order Transfer Functions | Krzysztof Oprzędkiewicz,Maciej Rosół,Wojciech Mitkowski | Oprzędkiewicz, K., Rosół, M., Mitkowski, W. (2023). Modeling of Thermal Processes in a Microcontroller System with the Use of Hybrid, Fractional Order Transfer Functions. In: Pawelczyk, M., Bismor, D., Ogonowski, S., Kacprzyk, J. (eds) Advanced, Contemporary Control. PCC 2023. Lecture Notes in Networks and Systems, vol 708. Springer, Cham. DOI: https://doi.org/10.1007/978-3-031-35170-9_15 | Pages 158-172 |
| Abstract: In the paper the problem of modeling of thermal processes in microcontroller system is addressed. The proposed models allow to describe thermal processes during work of an evaluation system. The temperature in critical places of the system is measured using thermal camera. The proposed models have the form of hybrid transfer functions, containing both Integer Order (IO) and Fractional Order (FO) parts. The step responses of the proposed transfer functions are computed analytically. Results of experiments show that the proposed models are more accurate in the sense of Mean Square Error (MSE) cost function than typical transfer function models with delay. The proposed models can be applied to predict of overheating of microcotroller systems. |

| Abstract: The rapid development of robotics creates the need for systematic training and professional competence of workers, which caused many projects of teaching robots to be developed. Industrial robots are versatile manipulation machines, but they need appropriate tools and workstation equipment to perform their tasks. As part of the student PBL (Project Based Learning) project, a concept was developed and a prototype teaching workstation containing the Astorino educational robot with equipment was made. Elements of the workstation’s equipment enable the demonstration of selected capabilities of Industry 4.0, such as the Internet of Things and systems allowing RFID wireless identification of manipulated objects, among others. As part of the PBL project, gripper jaws integrated with an RFID sensor were developed, and identification range tests were conducted for different gripper configurations and manipulated objects with different types of RFID labels. The results show that the tested labels have a small read range of about 20–40 mm, which is related to the limitations of the 13.56 MHz HF RFID technology used, as well as the dimensions of the labels and the materials used. This parameter is of great importance in determining the applicability of RFID labels, so the results of the study will be used for further development work on RFID grippers. |

Creep Testing Machine Identification for Power System Load Optimization. In: Pawelczyk, M., Bismor, D., Ogonowski, S., Kacprzyk, J. (eds) Advanced, Contemporary Control. PCC 2023. Lecture Notes in Networks and Systems, vol 708. Springer, Cham. DOI: https://doi.org/10.1007/978-3-031-35170-9_11 | Pages 113-122 |
| Abstract: This paper presents the results of an identification study of a three-zone furnace of a single-sample creep testing machine. The steps leading to obtaining a model are described, including: preparation of the test stand, determination of parameters of the identification experiment, identification of the dominant disturbances, selection of excitation signal, selection of model structure, validation of the obtained results, and analysis of possible nonlinearities. The description of the research includes information on the applied software compensator for disturbances caused by changes in the supply voltage, with the help of which they were reduced to a level that made it possible to conduct identification experiments. A model with three inputs and three outputs was identified as a MIMO, MISO and SISO structure. The advantages and disadvantages of each of these solutions are presented. The model was validated using step response experiments. The paper also presents a method for including static nonlinearity in the model. |

| Abstract: This article presents the methodological background and an overview of recent applications of artificial autonomous decision systems (AADS), endowed with intelligent coordination algorithms. The research results comprise modelling the decision-making processes in autonomous anticipatory systems, specifically the decisions made in teams composed of robots and humans. These can be modelled as timed anticipatory networks. We present selected real-life applications of anticipatory decision support methods, such as industrial safety management systems and coordination of ground unmanned autonomous robot teams. New algorithms have been proposed to solve multicriteria combinatorial optimization problems that occur when selecting safety strategies, such as AADS evacuation from endangered areas. Decision analytics, based on reference sets, is proposed to solve optimal supervisory control problems related to coordinated autonomous robot deployment. Finally, we discuss the scenarios of future research on AADS and their applications in developing decision algorithms for teams of autonomous harvesting robots or robotic inspection of large industrial plants. |

| Earned Value Method in Public Project Monitoring | V. M. Molokanova | Molokanova, V.M. (2023). Earned Value Method in Public Project Monitoring. In: Pawelczyk, M., Bismor, D., Ogonowski, S., Kacprzyk, J. (eds) Advanced, Contemporary Control. PCC 2023. Lecture Notes in Networks and Systems, vol 708. Springer, Cham. DOI: https://doi.org/10.1007/978-3-031-35170-9_9 | Pages 86-102 |
| Abstract: The article provides an overview of project management development based on the earned value method at the present time. A separate discussion of the main factors related to the use of the earned value analysis in the management of public projects. The article considers the vision in the project management model of two issues: planning models and development models based on factual results. It gives the opportunity to show the project state at an early stage, and explain the core rules for possible management. The methodology of the implementation of an innovative project’s portfolio was initiated based on the analysis of actual demonstrations of the portfolio components, the earned value method, and forecasting costs for existing project groups. The proposed methodology allowed us to obtain good results for developing public project management. Approbation was carried out at the enterprise of LLC “CI-Center” (Dnipro, Ukraine). The obtained results allow for strengthening the method of informing about the introduction of the portfolio and constant adjustment based on the choice of possible ways of further development. A dynamic model of project management, planning, monitoring, and implementation of projects has been proposed for use. |

| A Tube-Based MPC Structure for Fractional-Order Systems | Stefan Domek,orcid.org/0000-0002-4056-5175 | Domek, S. (2023). A Tube-Based MPC Structure for Fractional-Order Systems. In: Pawelczyk, M., Bismor, D., Ogonowski, S., Kacprzyk, J. (eds) Advanced, Contemporary Control. PCC 2023. Lecture Notes in Networks and Systems, vol 708. Springer, Cham. DOI: https://doi.org/10.1007/978-3-031-35170-9_10 | Pages 103-112 |
| Abstract: In the paper a new structure to improve the robustness of Fractional-Order Model Predictive Control (FOMPC) are proposed. The method based on the modified Model Following Control (MFC) idea, with the Internal Model Control (IMC) concept, introduced by Skoczowski and Domek in []. This leads to a novel, tube-based fractional-order robust predictive control structure, named TFOMPC, which offer an additional degree of freedom in tuning a control loop for higher efficiency. It seems that the proposed TFOMPC approach has potentially great advantages, is simple to implement and easy to tune. Thanks to this, it can be used in many control systems of difficult, inaccurately identified objects, not only of a fractional-order. |

| A Majorization-Minimization Algorithm for Optimal Sensor Location in Distributed Parameter Systems | Dariusz Uciński | Uciński, D. (2023). A Majorization-Minimization Algorithm for Optimal Sensor Location in Distributed Parameter Systems. In: Pawelczyk, M., Bismor, D., Ogonowski, S., Kacprzyk, J. (eds) Advanced, Contemporary Control. PCC 2023. Lecture Notes in Networks and Systems, vol 708. Springer, Cham. DOI: https://doi.org/10.1007/978-3-031-35170-9_8 | Pages 76-85 |
| Abstract: The wide availability of effective and efficient convex optimization algorithms makes convex relaxation of optimum sensor location problems enjoy high popularity. The main drawback of this approach, however, is that the performance gap between the optimal solution of the original combinatorial problem and the heuristic solution of the corresponding relaxed continuous problem can hardly be neglected. As a countermeasure, the original design criterion is often extended by addition of some kind of sparsity-enforcing penalty term. Unfortunately, the appealing problem convexity is then lost and the question of how to control the influence of this penalty so as not to excessively deteriorate the optimal relaxed solution remains open. This is why an alternative problem formulation is proposed here, in which the sparsity-promoting term is directly minimized subject to the constraint that the efficiency of the sensor configuration with respect to the employed design criterion is no less than an arbitrarily set threshold. This brings the degree of optimality of the produced solution under direct control. An efficient majorization-minimization algorithm is then employed in combination with generalized simplicial decomposition to produce sparse relaxed solutions. The attendant computations boil down to solving a sequence of low-dimensional convex optimization problems, which constitutes a clear advantage of the proposed technique. |

| Calculation Method of the Centrifugal Pump Flow Rate Based on Its Nominal Data and Pump Head Increase | Uliana Nykolyn,Petro Nykolyn | Nykolyn, U., Nykolyn, P. (2023). Calculation Method of the Centrifugal Pump Flow Rate Based on Its Nominal Data and Pump Head Increase. In: Pawelczyk, M., Bismor, D., Ogonowski, S., Kacprzyk, J. (eds) Advanced, Contemporary Control. PCC 2023. Lecture Notes in Networks and Systems, vol 708. Springer, Cham. DOI: https://doi.org/10.1007/978-3-031-35170-9_7 | Pages 69-75 |
| Abstract: It has been developed the method to calculate the volumetric flow rate for an energy audit investigation of centrifugal pumps with electric drives based on a previously created mathematical model using the principles of electrohydraulic analogy. The energy efficiency of the centrifugal pump was assessed through the implementation of an informative parameter - the load angle. This angle characterizes the operation mode of the power unit. The flow rate of the centrifugal pump due to the head gradient is calculated. The mutual dependence of the pump load angle on its volumetric flow rate is shown. This approach makes it possible to reduce financial costs and technically simplifies the energy audit, as there is no need to purchase an ultrasonic flow meter and its installation. The head characteristics of one of the centrifugal pumps were constructed using the proposed method. In addition, the developed method makes it possible to evaluate the energy efficiency of centrifugal pumps of small and medium power. |

| Aspects of Measurement Data Acquisition and Optimisation in the Energy Transformation of Industrial Facilities | Lukasz Korus,Andrzej Jabłoński | Korus, L., Jabłoński, A. (2023). Aspects of Measurement Data Acquisition and Optimisation in the Energy Transformation of Industrial Facilities. In: Pawelczyk, M., Bismor, D., Ogonowski, S., Kacprzyk, J. (eds) Advanced, Contemporary Control. PCC 2023. Lecture Notes in Networks and Systems, vol 708. Springer, Cham. DOI: https://doi.org/10.1007/978-3-031-35170-9_4 | Pages 39-48 |
| Abstract: This article deals with the problem of energy management, understood as the effort to minimise the energy consumption in the industrial facilities by continuous improvement approach. Due to the fact that multi-level Decentralised Control Systems (DCS), with the main focus on optimising energy consumption in small and medium enterprises are still rarely used, the continuous improvement approach based on Deming-like cycle using data collected by Data Acquisition and Presentation Systems from measuring devices is often used in practice. This paper presents a high-level process used in companies to drive energy management in an efficient way, and the main objectives defined for such an approach. It also provides more practical information on infrastructure configurations, IT components and applications of data collection and presentation systems. |

Continuous-Time Dynamic Model Identification Using Binary-Valued Observations of Input and Output Signals. In: Pawelczyk, M., Bismor, D., Ogonowski, S., Kacprzyk, J. (eds) Advanced, Contemporary Control. PCC 2023. Lecture Notes in Networks and Systems, vol 708. Springer, Cham. DOI: https://doi.org/10.1007/978-3-031-35170-9_5 | Pages 49-58 |
| Abstract: In the paper an approach to the identification of linear continuous-time dynamic systems based on acquired binary-valued observations of their input and output signals is presented. In the presented approach the binary-valued observations are interpreted as disturbed measurements of the corresponding original continuous-time input and output signals and system models are estimated using classical linear dynamic system estimation methods. The properties of such the approach are illustrated with three simulation examples. In these examples, frequency responses are identified using the empirical transfer function estimator, parametric models are recovered from the frequency responses identified, and finally, parametric models are identified directly from the binary-valued observations acquired. |

In: Pawelczyk, M., Bismor, D., Ogonowski, S., Kacprzyk, J. (eds) Advanced, Contemporary Control. PCC 2023. Lecture Notes in Networks and Systems, vol 708. Springer, Cham. DOI: https://doi.org/10.1007/978-3-031-35170-9_3 | Pages 27-38 |
| Abstract: The increase of energy prices has a substantial influence on the need of development of efficient control algorithms for the HVAC systems. However, testing of such algorithms in real buildings is usually expensive due to long time constants and unpredictable and unrepeatable weather conditions. Therefore, building simulation software plays an important role in the process. In this paper, the design of a building HVAC system simulator developed within the “Stiliger” project is presented. The simulator operates based on the data including all the necessary building construction details. The paper compares the results of the simulations with the measurements on a real, existing building, which was modeled. The comparison shows good agreement of the indoor temperatures in the simulation and in the real building. |

| On Mikhailov Stability Conditions for a Class of Integer- and Commensurate Fractional-Order Discrete-Time Systems | Rafał Stanisławski,Marek Rydel | Stanisławski, R., Rydel, M. (2023). On Mikhailov Stability Conditions for a Class of Integer- and Commensurate Fractional-Order Discrete-Time Systems. In: Pawelczyk, M., Bismor, D., Ogonowski, S., Kacprzyk, J. (eds) Advanced, Contemporary Control. PCC 2023. Lecture Notes in Networks and Systems, vol 708. Springer, Cham. DOI: https://doi.org/10.1007/978-3-031-35170-9_2 | Pages 16-26 |
| Abstract: The Mikhailov stability condition is a classical stability test for continuous-time systems, similar to the well-known Nyquist method. However, in contrast to the Nyquist criterion, the Mikhailov stability tests do not reach considerable research attention. This paper introduces an extension of Mikhailov stability condition for two classes of a discrete-time system in terms of linear time-invariant system, and fractional-order one based on ‘forward-shifted’ Grünwald-Letnikov difference. Simulation experiments confirm the usefulness of the Mikhailov methods for stability analysis of discrete-time systems. |

| Abstract: Information technology is rapidly developing and finding practical applications in various fields of human activity. Relevant is the study of technical systems. The final functional action of most of them is the delivery of a formed signal and, accordingly, a mechanical action on the object. The study consists of two parts: information technology and an executive mechanism. These components combine two main conditions: stability and functionality in operation. A rational choice of the parameters of the components is a common requirement for ensuring their stability and functionality. Modeling is used to fulfill this requirement [–]. In the process of studying technical systems using the created model, the interaction of various parameters is taken into account, which determines the overall stability of the operation and the efficiency of the given mode of operation of the system. It should be noted that solutions to most problems are visualized by graphical dependencies. Visualization and study of complex and simple functional dependencies in multidimensional spaces of models of multiparametric systems, which include technical systems, are reduced to formalized geometric operations on a variety of surfaces and hypersurfaces that represent geometric models of these dependencies [–]. The nonlinearity of the parameters that are part of the coefficients of various equations requires the use of tools that are effective for studying a particular class of systems. |

| Abstract: A proper control in a complex system, such as Wastewater Treatment Plant (WWTP) with each year is becoming increasingly important. High quality control can minimize an environmental impact as well as reduce operational costs of the WWTP. One of the core issues is providing adequate dissolved oxygen (DO) concetration for microorganisms used in a treatment process. An aeration process of the wastewater realised by an system consisting of blowers, pipelines and diffusers generates a large proportion of the costs. This paper presents an employment of a nonlinear adaptive control algorithm Extremum Seeking Control for improved control of DO. For the control design process, models of the aeration system and the biological processes are implemented. The control results based on performed simulation tests are presented. |

| Abstract: The work concerns non-parametric identification of time-varying non-linear characteristics. Two algorithms have been proposed. The first - based on kernel regression, and the second - based on the concept of nearest neighbors. Forgetting factor and number of selected neighbors are optimized to ensure a reasonable balance between bias and variance of the estimators. An empirical tuning algorithm minimizing the upper bounds of the tracking error has been developed. Illustrative experimental studies were also carried out. |

| Abstract: Multi-criteria optimization is increasingly used to build classifier ensembles, including for the imbalanced data classification task. Then we have the problem of optimizing at least two criteria related to the prediction quality of the minority and majority classes, or the so-called classification precision. The paper proposes - a new method for building decision tree ensembles. It uses the optimization algorithm to return a diverse pool of base classifiers by selecting different feature subsets on which they are trained. From the pool of non-dominated solutions, the final ensemble is chosen using the method. Modifying the weights of the algorithm allows the user to select the appropriate solution in the context of the user’s expectations (i.e., it indicates how important each optimization criterion is to the user). It is worth noting that during the classifier ensemble training, the features selected for the base classifiers result from the optimization process, and not as in the case of popular algorithms employing the approach (such as ), where attributes are selected randomly. Thus, the proposed method has an advantage over the mentioned approach, confirmed through a comprehensive set of computer experiments. |

| Abstract: The article addresses the problem of identifying and controlling cascade systems using B-splines. This article proposes a classification of identification approaches at the level of experiment planning. The use of classical identification methods, based on the response of the system to a well-defined standard test signal, in some cases is not possible to use in cascade systems. A method based on B-splines, allows for system identification using any input signal. This allows for a wider range of identification scenarios. This paper tests the B-spline identification method for a heating model of a building. The article also points out a number of problems arising from the application of the method. It is not a self-sustaining procedure that guarantees obtaining a solution – in particular, with badly chosen parameters, the method may not produce a solution. The problems and some suggestions are made for the appropriate implementation of the algorithm. |

| Abstract: In this paper, a Lagrangian relaxation approach to the problem of minimization of the total weighted tardiness is presented. The approach can be used both to solve the original problem as well as to obtain a high-quality lower bound for the branch-and-bound method. The problem was further decomposed into upper and lower problems. For the upper problem, an approach using a local-search metaheuristic is proposed instead of a subgradient method from the literature. Several variants of both methods are then implemented and compared through a numerical example using OR library problem instances. The results prove the viability of the metaheuristic approach as with little calibration it is able to match or outperform a refined subgradient method. |

| Abstract: This paper considers the problem of maximizing the total weighted number of on-time jobs on a single machine. Using the problem as a case study, we present a new approach to solving -hard discrete optimization problems using D-Wave’s QPU quantum processor architecture implementing quantum annealing. Although optimization on a quantum machine does not guarantee optimality, the hybrid method of construction of the partitioning and constraint algorithm proposed in this paper, using together CPU and QPU as well as Lagrange relaxation for upper bounds determination, makes it possible to determine the exact, optimal solution. |

| Abstract: Stochastic control with quadratic cost and partial, noisy observation has been considered. It has been proven, under rather natural assumptions, that the cost function is lower bounded by two types of bounds. The first one is convex increasing function of the mutual information between observations and state of the system. The second bound is decreasing function of the mutual information between control sequence and the state. Considerations are illustrated with simple example. |

| Abstract: Estimation of host vehicle motion is a necessary component of a control algorithm for automotive Advanced Driver Assistance Systems (ADAS). Vehicles with ADAS features are equipped with radars and cameras, which can be used to complement the conventional methods of observing host motion by inertial estimators. Automatic Emergency Braking is a basic feature of ADAS, which may result in request for significant tractive force requests. This work reports experimental results comparing radar-based method of host vehicle speed estimation with an inertial estimator. Maneuvers of interest are straight line braking and acceleration events at road surfaces with high and low friction coefficients. |

| Abstract: In this paper we consider diagnostics of induction motor faults via measurement of startup current. Data collected has a form of time series of varying length and magnitude, as it strongly depends on voltage supply. In this work we focus on functional representation of those signals in time domain. We show that we can effectively model those signals with taking uncertainty under consideration and using those models create efficient classifier. For this purpose we have used Bayesian Gaussian mixture model classifier, which creates models of all healthy and faulty states and the entirety of population of possible cases. We show how our approach works and how it behaves under significant randomization. |

| Abstract: This paper presents an application of the statistical moments and respective moment ratio diagrams (MRD) to the control performance assessment (CPA). Moment ratio diagram is the statistical visualization method that allows to present graphically properties of the empirical observations. At the same time CPA is a well established research area delivering indexes and methodologies to measure the control loop quality. Statistical properties of variables from the system provide information about the performance thus moment ratio diagrams may represent properties of the control system. In the considered research moment ratio diagrams are used to assess the quality of real PID based control system and to present its performance graphically. It is shown that control system quality can be efficiently visualized using moment ratio diagrams. The method is validated using the laboratory mechanical servomechanism, which inherently includes into the picture real life aspects and limitations. |

| Abstract: Dynamic response of ships running at sea are usually investigated in frequency domain. The time domain approach is adapted to simulators and evaluation and design of motions control systems applied onboard. The time domain response pay a major role in the design and control of unmanned sea vessels. The most of modern tools computing ships behaviour in sea are based on potential code with frequency domain output of hydrodynamic coefficients and excitation forces. Time-domain models of marine vessels that rely on frequency domain data are generally evaluated using the Cummins equation with convolution terms. This approach is sometimes impractical in design of control systems as well as for real time simulations. This paper introduces application of eigenvalue realization algorithm to find state space model realization of Cummins retardation function. The matrices of hydrodynamic coefficients and excitation forces are obtained by frequency domain computations. Further simulations of selected ship responses evaluated by proposed method are compared with scaled model tests in representative wave realizations. |

| Abstract: The modern maritime industry is moving toward the development of technology that will allow for full or partial autonomy of ship operation. This innovation places high demands on ship performance prediction techniques at the design stage. The research work presented in the article is related to the design stage of the ship and concerns methods for prognosis and evaluation of the specific operational condition of the ship, namely the dynamic positioning (DP). The paper is an introduction to a study that seeks to assess the impact of using advanced simulation models on the accuracy of DP capability prediction. To this end, the Potential Theory and methods of Computational Fluid Dynamics (CFD) are applied to determine the mathematical model of the ship. The parameters obtained in the course of simulation studies have been compared to those obtained experimentally. The study showed that the proposed method is sufficiently accurate for the purposes of determining the added mass and damping coefficients of the ship. Consequently, it is considered that design offices could improve the accuracy of the DP prediction by using mathematical modeling and numerical methods to estimate selected ship parameters. |

| Abstract: Radars are widely used in automotive to deliver both interior and exterior environment sensing capability and enable functions such as cabin monitoring, automatic emergency breaking, adaptive cruise control etc. Complex verification of automotive radars is needed to ensure the safety of the final product. Validation is performed on many levels such as climate chambers tests, electromagnetic emission compliance, algorithm robustness and much more. Computer simulations are also widely used for this purpose. Automotive radars are modelled on several levels of abstraction starting from the physical wave propagation analysis to high level system output simulation. In the article a new approach to the detection level simulation of automotive radar is presented. It is based on the neural network system modelling. The performance verification based on publicly available nuScenes dataset is presented that allows to compare the results between different models. |

DOI: https://doi.org/10.1007/978-3-031-35173-0_24 | Pages 245-253 |
| Abstract: One of the most difficult aspects of planning the motion of autonomous vehicles is the uncertainty regarding the future behavior of other road users. Ensuring a safe motion often requires preparing for multiple plausible outcomes of a current road situation. To achieve this, we propose an optimization-based trajectory generation method capable of planning an efficient motion while ensuring a collision-free behavior with respect to several conflicting hypotheses. The method generates multiple control trajectories that overlap for a certain time period, ensuring that the initial part of the trajectory can be continued with a safe motion regardless of which hypothesis will prove to be true. One notable application of the proposed method is an implementation of a Fail-Safe Planning concept, where the vehicle’s trajectory is planned based on a most plausible prediction of the other road users’ behaviors while simultaneously a fail-safe trajectory is generated based on a worst-case prediction, ensuring the existence of a collision-free maneuver that can be used in emergency situations. |

| Abstract: The paper describes real world experiments conducted on Slovakia Ring. The main objective of these experiments is to analyze the influence of the relative speed between the ego and the target vehicle on the data provided by the sensors and the perception algorithms executed on these data. During the experiments, data obtained by camera, GNSS/IMU location sensor and lidar are analyzed. The results show that the relative speed has an influence on the environment perception by the sensors and has to be compensated for. |

| Abstract: Autonomous control of scaled racing cars is an increasingly popular approach for testing and presenting new control algorithms while also reducing the operational costs required to bring such a model along with a proper racing track to life. In most cases where autonomous vehicles come into play, the environment map is not known a priori, in which case the algorithm should sufficiently drive the car in real time, without having planned an optimal trajectory. This study presents a reactive method based solely on LiDAR readings that successfully navigates the car through unknown dynamic environments with obstacles, taking into account the principle of safety: not to crash into obstacles or other vehicles. We show that the algorithm significantly outperforms two other existing reactive algorithms and renders a cost-effective solution to the problem of autonomous driving on unknown maps, as well as it renders itself as a possibly good “specialist" model in Expert Intervention Learning (EIL) approach-based models for autonomous vehicles, especially the F1TENTH cars. |

| Abstract: Dermoscopic image analysis is an important field that helps in skin cancer diagnosis. Removing image artefacts, such as hair or measuring tools, remains challenging due to the lack of datasets with artefact ground truth and clear samples. In this work, we present a comprehensive study of different segmentation and inpainting algorithms, as well as present our own solution for segmentation. To the best of our knowledge, this is one of the first papers that introduce both qualitative and quantitative analysis of framework performance at different stages, by evaluating the proposed methods on an artificially created dataset, based on ISIC database modification. We are able to show that our methods achieve a Dice score of 0.59 on hair segmentation and 51.36 Peak signal-to-noise ratio (PSNR) in image inpainting. |

| Abstract: The paper presents an optimization-based approach to the testing of software systems. In the proposed approach, test case selection is combined with test execution, and these two activities are conducted in parallel. Executing a test case consists of exiting the system with an input and comparing the resulting output with the expected one. The test selection procedure is iterative and is driven by the optimization algorithm. The performance index to be maximized is defined as the distance between the actual and expected outputs. This formalism will allow one to find areas that have been implemented incorrectly. An empty set of test cases will give some confidence that the system has been properly implemented. The main advantage of the approach is focus on error-prone scenarios that leads to drastically reduced number of tests to be executed, and consequently to less testing effort. An example is included to verify the approach and to present its applicability for industrial projects. |

| Abstract: The increasing complexity and wide applicability of software control systems requires the use of advanced and automated development and testing methodologies to meet time-to-market constraints, quality assurance and safety standards. In this context, the applicability of model-based development (MBD) and model-based testing (MBT) methodologies to such systems has gained attention in the last decade. The paper presents an integrated model-based approach to testing software control systems whose models are described by linear differential equations. The approach presented concerns conformance testing and includes the notation of tests, the implementation of a test comparator, the calculation of test coverage, the generation of test cases, and the execution of the tests. Finally, an example of a two-dimensional system is used for an experimental evaluation of the theoretical analysis and to present a perspective on the applicability of the approach for industrial projects. |

| Abstract: Deep learning algorithms are rapidly growing and powerful algorithms that achieve very high results in tasks such as image classification, recognition or segmentation, speech recognition, and many others. The disadvantage of using these methods is that they often need a lot of computational resources. The significant development of mobile devices has allowed the use of these algorithms in mobile applications. The wide availability of mobile phones (smartphones) makes it possible to improve many areas of people’s lives. Particularly beneficial can be the use of such applications in medicine. We have created this kind of application in the field of dermatology for controlling skin lesions. Such a mobile app can relieve the health service and allows faster detection of potential abnormalities. Our application, based on the photo of the lesion taken by the user with his mobile phone, will inform him whether his skin lesion should be checked by a dermatologist immediately because it looks suspicious, should be observed periodically, or whether it is safe and nothing dangerous should happen to it. This article presents the crucial aspects of creating a mobile application for medical skin lesions classification, especially training the classification model. |

| Abstract: The purpose of this study was development of for a photovoltaic panel (PV). A prototype test bench was built with dimensions that allow testing of a single PV module. As a source of artificial light, high-power halogen bulbs were used. A test bench was created to perform a series of measurements of the used bulbs. Based on these measurements, irradiance functions were determined dependent on distance or supply voltage. Those functions were used to create a model, based on which it was possible to obtain the optimal placement of the bulbs above PV module, while ensuring adequate irradiance to verify the performance of the photovoltaic panels. |

| Abstract: With the deployment of 5G networks across European countries, researchers and industry can consider research and development of new Cellular-V2X (C-V2X) applications for the environment of Connected and Cooperative Automated Mobility (CCAM) with vision of rapid development into the daily life of vehicle drivers. In order to have these services safe and reliable, several criteria of the cellular network performance across various parameters have to be met. These criteria are described in the 3GPP Release 15 and partially updated in Release 16. In this paper, we performed and concluded several experiments with a vehicle driving across different types of Slovak roads, where we evaluated cellular network performance in terms of Quality of Experience parameters and we compared the results with the requirements set by 3GPP documents. As a part of this, we also provide comparison of meeting these requirements between using 5G-NSA (Non-Standalone, all 5G networks currently in use in Slovakia are these type of 5G network) and 4G (LTE) network. |

| Abstract: In the case of 3D printing, the task of placing or nesting means the optimal distribution of elements in the workspace. The primary goal is to produce as many items as possible in one technological process while maintaining the desired strength and visual parameters. The task is difficult to solve, because the objects considered have different shapes, different dimensions, specific technical features (e.g. shrinkage due to heat dissipation). Also the planning process has several restrictions (e.g. height of elements in different production areas). The article presents an algorithm of intelligent packaging of items, dedicated to use in CAM systems, for manufacturing with 3D and 5D printers. The algorithm, is composed of several elements based on physical interactions: the force and torque fields and the contact and dissipative forces. Additionally, objects can modify their local force fields during interactions, depending on the technological parameterization used. An innovative solution, used in nesting algorithm, consists of the application of the invented idea called ‘profile of emotions’. This idea is a function that reduces the level of physical interactions over time. The result of profiling gives number of stable solutions, i.e. a set of proposals for packing items in the workspace. The article also includes a description of the developed software, graphical interpretation of the process and test results. Tests were carried out using Matlab. |

| Abstract: The work is a report on the implementation of interdisciplinary group project classes conducted in accordance with the Project Based Learning approach. The aim of the project was to develop an automated station for measuring the curvature of metallurgical charge and to create its technical documentation. The station is intended to work in cooperation with devices of an automated line for spreading and transporting metallurgical charges, which is a part of the technological line for hot rolling. The task of the station is to identify the curvature value, so that a charge with exceeded parameters does not proceed to the next stage of the process (the goal is significant in terms of eliminating defects). The final outcome of the project was to be a complete technical documentation of the designed station along with the measurement algorithm. Additionally, a laboratory test station and a system design for use in real industrial conditions were developed. |

(eds) Advanced, Contemporary Control. PCC 2023. Lecture Notes in Networks and Systems, vol 709. Springer, Cham. DOI: https://doi.org/10.1007/978-3-031-35173-0_34 | Pages 360-370 |
| Abstract: In the Two Rotor Aerodynamical System two control loops can be distinguished. Each uses the values of both angles - azimuth and pitch. This makes it possible to use parallel or cascade control on both loops. In the article, it was decided to use the system to check the behavior of hybrid control, which would be a combination of both versions. In azimuth angle loop the parallel version was applied. The pitch angle loop used cascade control. Two versions were prepared - the first one with only Proportional Integral Derivative (PID) controllers and the second one with one Fractional Order Proportional Integral Derivative (FOPID). The Grey Wolf Optimizer algorithm was used for optimization purposes. Simulations were carried out in the MATLAB/Simulink environment. The graphs of both angles, the values of the cost function and the execution times were used as a comparison between controllers. |

| Abstract: Typically, Model Predictive Control (MPC) algorithms minimise the sum of squared predicted control errors, i.e., the L norm. This work reviews the possible cost functions that may be used in MPC. Eight different cost functions are considered and their usefulness is investigated. For a neutralisation reactor benchmark, the influence of the cost function on the resulting control quality is compared in terms of as many as eight indices. All studied approaches are compared in two scenarios: with no process disturbances and when measurement noise and a disturbance affect the process. |

| Abstract: One of the most significant issues in the cities is the heavy traffic that everyday citizens are involved with. In recent decades, various sciences, such as computing science and control and traffic science have been incorporated to address this problem. In this paper, theoretically, the Terminal Sliding Mode Control (TSMC) method is proposed to control the traffic flow in urban networks. Firstly, a two regions model for urban traffic with various uncertainties and external disturbances is considered; subsequently, the Lyapunov stability method is employed to control the urban traffic flow in this model by using designed control inputs and adaptive laws. Finally, a numerical simulation for a case study is performed in Simulink/MATLAB to reveal the effectiveness of the proposed designs in this paper. |

| Abstract: The presented concept of non-linear adaptive control can be used for any system with complex, nonlinear dependencies of control and state variables. It can be applied even when the plant model is partially represented by digital data only. The main idea is to propose a simple fuzzy model to approximate a nonlinear map of control and state, and to develop a fast numerical inversion technique providing on-line control which ensures the desired output of the fuzzy model. Our aim is to obtain a short execution time, to enable applications in DSP-based, fast control systems. Moreover, on-line adaptation of the model parameters should improve the system performance, even if the initial model is inaccurate. The developed fuzzy inversion technique can cooperate with many nonlinear adaptive control approaches: adaptive backstepping, adaptive model following etc. |

| Abstract: The synchronization of systems with the goal of securing communications is a very interesting and recent topic. This paper proposes the Fast Terminal Sliding Mode Control (FTSMC) method to design control inputs for synchronizing four different communication systems, Volta, Coullet, Chen and A.M.Rucklidge. Synchronization of these systems can be used in a variety of applications. Some of the key features of the proposed designs are that these inputs are robust against the variety of uncertainties of the system model and external disturbances. Also, the finite time stability of these systems is guaranteed by using designed inputs. Additionally, these inputs eliminate destructive and undesirable chattering phenomena thoroughly. |

| Abstract: In this study, a robust controller for a quarter-car model of an active inerter-based suspension in the presence of external disturbance has been investigated. Its prime goal is to improve the inherent trade-offs among ride quality, handling performance, suspension travel, and power consumption. Inerters have been widely used to suppress undesirable vibrations of various types of mechanical structures. First, the dynamics and state space of the active inerter-based suspension system were achieved for the quarter-car model. To meet the specified objectives, and guarantee the prescribed disturbance attenuation level of the closed-loop system, the Lyapunov stability function, and linear matrix inequality (LMI) approaches have been used to fulfill the robust criterion. Furthermore, to limit the gain of the controller, some LMIs have been added. Numerical simulations show that an active suspension based on inerter performs much better than a passive suspension with inerter and active suspension without inerter. |

| Abstract: Inspired by IMC approach, tuning rules for PID control of time-delay plants such as pure TD, FOPTD, SOPTD and IPTD are developed. Control systems for the first three plants can be designed in a consistent way, since they are described by the same transfer function for commonly used controllers. Analytic rules are given for critical damping. Nomograms characterize overdamping for settling time specification and underdamping for overshoot. Practical experiment confirms fairly good correspondence of closed-loop responses to specifications. |

| Abstract: Vibration characteristics of a low-cost measurement system based on the ADXL100x micro-electromechanical system (MEMS) sensors are presented in this paper. The discussed measurement system consists of two ADXL100x MEMS accelerometers, interfaced with a BeagleBone Black microcontroller. The accelerometers were mounted on a vibration exciter equipped with a reference accelerometer. The vibration exciter was feeded using a function generator with various frequencies and acceleration signals. Vibration characteristics were investigated by comparing reference and recorded frequencies, sensitivity illustration over various frequencies, and sensitivity effects on different accelerations. The results demonstrate that the ADXL100x MEMS sensor is efficient and suitable for high-sensitivity applications. |

| Abstract: Eddy current arrays (ECAs) have become increasingly popular in non-destructive testing (NDT) due to their ability to provide fast and accurate inspection results. However, like any other NDT method, ECAs have their limitations and drawbacks. This article discusses some of the problems associated with using ECAs for NDT, including the effect of array size and geometry on inspection performance, the influence of material properties on signal interpretation, and the challenge of optimizing inspection parameters for different inspection scenarios. The article also highlights recent advances in ECA technology that aim to overcome some of these problems, including the use of advanced signal processing techniques and the development of novel array designs.

| Abstract: The paper studies the problem of controlling the orientation of an Earth observation satellite with a single solar panel. For a simplified model of a satellite we develop a control algorithm which allows to asymptotically track a harmonically changing reference signal. As a mathematical tool we employ the general regulation theory. The obtained theoretical results are successfully tested on a numerical example. |

| Abstract: Both fault-tolerant design (FTD) and fault-tolerant control (FTC) are receiving increasing attention from the scientific community. Both intend to develop and implement solutions for accommodating faults which are inevitable in complex technical systems. However, up to no, little scientific activity was aimed at integrating those two promising approaches. This paper describes a detailed investigation of common aspects and interfaces between FTD and FTC as well as a sensible combined process. This investigation was based on the development of automated guided vehicles (AGVs) together with the appropriate control and diagnosis algorithms and systems. |

On the basis of the obtained researches it is proposed to make the analysis on indicators total harmonious distortion and reactive capacity. |

| Abstract: This study is aimed to analyze a piezoelectric energy harvesting system made of a smart lead zirconate material applied to the hybrid excitation in the form of mechanical vibrations and airflow. The system utilized a monolithic PZT plate composed of ceramic-based piezoelectric material, under its bending, the voltage is generated. In the experiment, a specialized measurement system based on Arduino and wind tunnel were used to conduct the tests on a bluff-body shape mounted on an elastic beam with a piezoelectric attached to a support with arms. The elastic beam and arms were linked with springs, that change the internal characteristic frequency of the energy harvester. The air-flow velocity and forced vibration frequencies were varied, and the output voltage signal and linear accelerations were recorded during the variable excitation. The effect study is the conclusion that the system’s highest voltage efficiency was achieved through a combination of mechanical vibrations and air flow. Additionally, the study generated the correlation between the RMS voltage as a function of the air-flow velocity for resonance excitation frequencies. In the study, the area where the system could generate the highest output voltage under given excitation conditions was investigated. The above-described comparative analysis is conducted for two research objects differing in their mass. The proposed energy harvesting system concept can be used as a power supply for low-power consumption sensors. |

| Active Noise Control with Passive Error Signal Shaping - A Critical Case Study | Małgorzata I. Michalczyk,orcid.org/0000-0001-7162-5647 | Michalczyk, M.I. (2023). Active Noise Control with Passive Error Signal Shaping - A Critical Case Study. In: Pawelczyk, M., Bismor, D., Ogonowski, S., Kacprzyk, J. (eds) Advanced, Contemporary Control. PCC 2023. Lecture Notes in Networks and Systems, vol 708. Springer, Cham. DOI: https://doi.org/10.1007/978-3-031-35170-9_20 | Pages 216-224 |
| Abstract: In the paper an application of passive residual error signal shaping in active noise control (ANC) system is revisited. The shaping band-pass filter was designed to attenuate some frequency range of the disturbance (denoted by the shaping filter pass-band) and exclude some frequency range of the disturbance (denoted by the shaping filter stop-band) from operation of the internal model ANC system using the filtered-x least mean squares algorithm. The simulations results show that depending on the time horizon the algorithm may attenuate the disturbance in the whole frequency range. Thus, it can be impossible to exclude a frequency range from the adaptive ANC system operation by means of the shaping filter. This means that passive residual error signal shaping in adaptive ANC systems does not work as expected. |

| Abstract: The paper deals with the problem of simultaneous actuator and sensor fault estimation for linear dynamic systems on which influence unknown exogenous disturbances. The most common approach of dealing with fault estimation approach is that either actuator or sensor fault estimation schemes are provided in the literature. This paper proposes a kind of a fusion of those approaches which results with the capability of estimation of actuator and sensor faults which might appear in the system simultaneously. The novelty relies on that the unwelcome rate of change of the fault factor is vanished which simplifies the design problem. The methodology utilized in the paper to attain the robustness is the so-called Quadratic boundedness approach. In the final part of the paper, the illustrative example with the implementation to the laboratory Multi-Tank system is provided which shows the performance of the proposed approach. |

Neural Network Based Active Fault Diagnosis with a Statistical Test. In: Pawelczyk, M., Bismor, D., Ogonowski, S., Kacprzyk, J. (eds) Advanced, Contemporary Control. PCC 2023. Lecture Notes in Networks and Systems, vol 708. Springer, Cham. DOI: https://doi.org/10.1007/978-3-031-35170-9_21 | Pages 227-236 |
| Abstract: The paper focuses on designing an active fault detector (AFD) for a non-linear stochastic system subject to abrupt faults. The neural network (NN) based models of the monitored system and their prediction error uncertainties are identified using historical input-output data obtained from the system under fault-free and all considered faulty conditions. The fault detector is based on a multiple hypothesis CUSUM-like statistical test that uses the identified NN models. The quality of decisions provided by such a detector is improved by a closed loop input signal generator. The input signal generator is represented by another NN and it is designed using a reinforcement learning method. The proposed AFD is illustrated by means of a numerical example. |

Fault-Tolerant Fast Power Tracking Control for Wind Turbines Above Rated Wind Speed. In: Pawelczyk, M., Bismor, D., Ogonowski, S., Kacprzyk, J. (eds) Advanced, Contemporary Control. PCC 2023. Lecture Notes in Networks and Systems, vol 708. Springer, Cham. DOI: https://doi.org/10.1007/978-3-031-35170-9_22 | Pages 237-249 |
| Abstract: This paper proposes a model-based fault-tolerant control system for wind turbines with power tracking above the rated wind speed. Due to the increasing share of renewable energy sources such as wind turbines in power systems, the latter must provide fast power tracking for frequency control. So far, these power-tracking control systems are not yet equipped with fault-tolerance characteristics. Therefore, an fault-tolerant control design using a reconfiguration block is proposed. In the reconfiguration block, a proportional-multi-integral observer calculates actuator faults if such faults should occur and eliminates their influence on the rated power tracking controller. An analytical model-based design method for the reconfiguration block is presented in detail. System simulations are used to show how this will improve the reliability of future power-tracking wind turbines. |

In: Pawelczyk, M., Bismor, D., Ogonowski, S., Kacprzyk, J. (eds) Advanced, Contemporary Control. PCC 2023. Lecture Notes in Networks and Systems, vol 708. Springer, Cham. DOI: https://doi.org/10.1007/978-3-031-35170-9_19 | Pages 205-215 |
| Abstract: This paper addresses the problem of assessing fault distinguishability of faults. Fault distinguishability is understood as the ability of a diagnostic system to isolate faults. The objective of diagnosis is the early detection and accurate isolation of the faults that have occurred. The accuracy of diagnosis depends on the fault distinguishability achieved. The problem of assessing the fault distinguishability is therefore extremely important. This provides an opportunity to compare the effectiveness and assess the quality of different solutions of a diagnostic system. This paper proposes two new metrics for fault distinguishability assessment, providing the possibility to evaluate and compare the performance of fault isolation carried out based on both signatures or symptoms with both binary or trinary diagnostic signal values. The proposed metrics allow analysis of fault distinguishability for all diagnostic inference approaches based on Fault Signature Matrix as well on Fault Isolation System. |

| Abstract: The research objective is to develop and test mathematical model of gas storage in the layered aquifer with poorly permeable interlayer if plane-parallel and axisymmetric filtration takes place. The paper evaluates the gas-hydrodynamic operational indices of the underground gas storages within aquifers in the South East Ukraine. Comprehensive approach has been applied involving collection, systematization, and analysis of actual data on filtration and physicomechanical properties of enclosing rocks impacting formation of natural and technogenic deposits as well as analytical and numerical methods to solve equations of the gas-water contact shift under different conditions. A gas-hydrodynamic model of underground gas storage within the nonuniform aquifer has been substantiated to calculate its cyclic operation in the three-layered seam taking into consideration crossflows through a poorly permeable stopping. The calculation results show significant impact of characteristics of the layered porous environment on the gas water contact transfer through certain seams. The derived new technique linearizing a system of differential equations to identify pressure within a reservoir is generalization of the earlier applied procedures with introduction of ‘boundary schemes’. The calculation results demonstrate significant impact of the layered porous environment on the gas water contact transfer through certain seams. The findings may be applied while making evaluations at the stage of gas storage design within aquifers. |

| Abstract: In practice, data from the process typically can be collected only for limited ranges of the entire area of process operation, which limits the quality of data-driven models. On the other hand, a fundamental process model may be available but flawed due to measurement noise or immeasurable model parameters. We recommend the described Physics-Informed Hybrid Neural Network (PIHNN) model to model the process precisely. It is comprised of a series of black-box sub-models; we use Gated Recurrent Unit networks (GRU) in this role. Neural and fundamental sub-models are combined using a fuzzy data fusion block. We report the model development procedure for a benchmark pH reactor and show that the model gives very good accuracy. Finally, the PIHNN model is implemented in a Model Predictive Control algorithm. |

| Abstract: Based on thermodynamic constants, the concentration limits of the initial substances and the range of pH values, at which deposition of heavy metals chalcogenides films without impurities of by-products is possible, were calculated. The boundary conditions of the formation of low soluble forms of the zinc subgroup metals chalcogenides have been calculated. The choice of the working solutions components for the sulfides and selenides thin films of metals (Zn, Cd, Hg) synthesis by the deposition method from aqueous solutions is substantiated. The problem of complex intermolecular interactions in the volume of the working solution between complexed metal ions and the chalcogenizer was solved based on mathematical calculations. Based on the calculations, a reasoned selection of the optimal conditions for the synthesis of thin films, especially the working solution’s qualitative and quantitative composition, was made for their further use in semiconductor electronics. |
