This study addresses the affine formation maneuver control of cooperative multi-agent systems (MAS) having periodic inter-agent communication for both static and dynamic leader cases. Here, we focus on the leader-follower MASs. The primary aim of the control system is to steer the entire collection of agents to produce required patterns (geometric) along with any required maneuver through the direct control of only few a selected agents referred to as leaders. Most of the existing works are constrained to either the individual agents communicate with each other in continuous-time or the sample-data scenario where the leaders are stationary or have constant acceleration or velocities. Here, we consider the scenarios where the velocities of the leaders can be time-varying or constant. Here, different cases are addressed and some control laws are proposed. Conditions are established to help guarantee the overall stability of the systems. A simulation study is employed for the illustration of our proposed laws. © 2024 IEEE.

This study explores the impact of natural measurement noise and cyber threats on renewable energy metering in smart energy systems, with a focus on wind turbines. The research examines the simultaneous distribution of diverse loads supported by energy storage devices, which enhances energy resource management and system efficiency. Additionally, the influence of cyber-attacks on wind turbine power measurement devices and the effects of natural noise and measurement failures on system operating costs and performance are analyzed. The findings highlight that cyberattacks induce a mean data deviation of 17.18%, significantly disrupting system reliability, while natural noise results in a deviation of 7.4%, indicating its notable yet lesser impact. These results emphasize the importance of advanced monitoring and mitigation strategies to safeguard renewable energy systems from disruptions caused by both noise and malicious interference. The proposed framework provides actionable insights for improving the resilience and efficiency of smart energy systems in practical scenarios. © 2025 IEEE.

The development of a dynamic model for a popular implemented solar power plant is a critical task for power engineers aiming to enhance the plant’s performance and reliability. In this study, we utilized the prediction error method (PEM), a robust algorithm for system identification, to capture the plant’s operational characteristics with precision. Additionally, we employed both recursive and hierarchical algorithms to identify the system parameters effectively. The results from each identification method are rigorously quantified and analyzed, allowing for a detailed comparison of their performance. This comprehensive evaluation not only highlights the strengths and weaknesses of each approach, but also provides valuable insights into their practical applications in the context of solar power systems. © The Author(s) 2024.

In this tutorial some basic linear algebra problems: basis change and projection, are discussed together with examples of their applications in signal and image processing. In typical linear algebra university courses perpendicular projections are only discussed. However, in image processing, for defining various color spaces, we need non-perpendicular projections. That is why this is the key problem in this tutorial. © 2024 Division of Signal Processing and Electronic systems, Poznan University of Technology (DSPES PUT).

This elaboration presents the synthesis of the Takagi-Sugeno type Fuzzy Logic controller realizing the programmable parameters of the state feedback controller together with the steady state current for the active magnetic levitation system. Closed-loop dynamics was calculated precisely with respect to the requested dynamics. Two cases were considered: fixed-and variable-closed-loop dynamics. The Fuzzy Logic controller was considered under four scenarios with linear, nonlinear, and constant in-range output. The study was supported by simulations and experimental investigations. The position of the levitating sphere stands as an illustration of the system in operation. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.

In this paper, we consider the problem of generalized Nash equilibrium (GNE) seeking in a class of contractive population games under a partial-decision information setup and subject to affine equality constraints. Namely, we consider multiple populations, each comprised of a large number of payoff-driven decision makers, and we embed a network topology ruling the exchange of information between the multiple populations. Conceptually, we consider that each population has an associated payoff provider entity, which yields the payoff signals to the agents of its corresponding population. The multiple payoff providers communicate through a (possibly non-complete) network to estimate the non-local information relevant to compute the payoff signals. As the main contribution, we formulate the dynamics of the payoff providers and we provide sufficient conditions to guarantee the asymptotic stability of the set of generalized Nash equilibria of the underlying game. To the best of our knowledge, this is the first paper to address the problem of GNE seeking in population games under partial-decision information. © 2024 IEEE.

This paper examines the Boost converter's chaotic behavior. A voltage mode controlled technique is being utilized to analyze the discrete-time mapping to determine the properties of the bifurcation that operate in a closed loop. By varying some parameters while holding others constant, the reference voltage and input voltage are used to examine the bifurcation diagram. It has been noted that the system becomes unstable and splits into two time-periodic systems, four time - periodic systems and then chaos takes over the system. These occurrences have been shown in the bifurcation diagram, therefore the converter's safe operating range can be determined and verified by using the time-domain waveforms and phase plots. © 2023 IEEE.

Efficient Safety Verification of Discrete Event systems 19

Efficient Safety Verification of Discrete Event Systems

Formal verification of safety properties is critical in many application areas. In this paper a survey of the most common and efficient methods is given. The different methods are compared for some typical scalable examples, both modeled by transition systems and Petri nets. The methods are based on symbolic computations and logic representations of both sets and transition relations. Reachability analysis is performed not only from the initial states to any forbidden states, but also in the opposite backward direction. The reason is that a system is also safe when no initial state is backward reachable from the set of forbidden states. For safe systems the number of backward reachable states from forbidden states is often much less than the forward reachable states from the initial states. The backward strategy is shown to be very efficient and often even better than the most efficient methods that are specialized on safety analysis. © 2023 IEEE.

In health care, it is crucial to organize patient care and resources based on the urgency level so that patients whose lives are in danger are treated as a priority. This study introduces a new algorithm, created in C# using new technologies such as ChatGPT, to improve the sorting and prioritizing of patients based on the National Urgency Level. The algorithm aims to demonstrate the possibility of real-time reporting of the occupancy level of all hospitals. This way, patients can head to the nearest and most available hospital based on both proximity and urgency level. To identify the urgency level, the algorithm utilizes a widely used external service, ChatGPT. Additionally, the algorithm calculates the average waiting time based on the number of patients, their urgency level, and the number of on-duty doctors. To achieve these goals, the algorithm's implementation has been carried out using modern technologies, such as C# programming language, ranging from the artificial intelligence service ChatGPT to entity framework for managing data in the Microsoft database. The article addresses two major issues, namely text-based classification into a specific category based on common characteristics, such as a patient's symptoms concerning a specific urgency level. The second issue is represented by the proposed calculation formula for real-time estimation of waiting time, based on the identified urgency level. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.
