The FDI system relies on two nonlinear adaptive observers (NAOs) to execute analytical redundancy between the actual measurements and estimations. Two mathematical structures are proposed for developing the NAOs, which are used to construct a bank of observers. Such a bank produces estimations of the ratio between experimental and theoretical air-fuel ratios (lambda λ), temperature, and pressure, which are continuously compared with the sensors' measurements, ensuring an uninterrupted diagnosis of the ICE sensors, even in case of total or partial fault. A threshold mechanism is incorporated into the FDI system, which is based on the variance analysis of residuals and the Euclidean norm of a sliding window vector to reduce false alarms during the partial faults diagnosis. The results of numerical tests with experimental data demonstrate the system's ability to accurately detect multiple and simultaneous sensor faults while preventing false alarms.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144121669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Load frequency control (LFC) has thus emerged as a primary challenge for maintaining power system stability and security due to the synchronization requirements of the entire power grid. This paper proposes a novel approach for LFC in multi-area power systems using a self-triggered control-based adaptive dynamic programming (ADP) framework integrated with fuzzy logic systems (FLSs). First, an H∞ distributed controller is developed based on the multi-agent system (MAS) model to mitigate the effects of parameter uncertainties and load disturbances. Additionally, with the increased deployment of phase measurement units and smart meters, real-time system measurements are expected to rise significantly. This trend underscores the importance of event-triggered control (ETC) in optimizing the use of communication resources. However, general-purpose devices often lack the dedicated hardware necessary to verify triggering rules. To address this limitation, we propose a novel self-triggered control (STC) mechanism. This STC calculates the control law based on the current state to determine the next state measurement, thereby eliminating the need for continuous plant monitoring. Simulation results on a multi-area system demonstrate that the proposed adaptive approach performs effectively in frequency regulation under conditions of load disturbance and parameter uncertainty.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144164358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The deep CNN-based system identification effectively captures the complex dynamics of the nano helicopter, enabling accurate modeling and compensation for uncertainties. The geometric integral control strategy enhances the system's robustness against unknown external disturbances, and ensures stable and precise flight performance. The feasibility of the proposed method is demonstrated through real-time flight experiments, which show strong robustness and accurate trajectory tracking performance. Additionally, the tuning process is simplified due to the adaption nature of the deep learning-based approach, reducing the need for extensive parameter adjustments. The data requirements are also minimized, as the deep CNN can be trained with a relatively small dataset, making the method more practical for real-world applications. The results indicate that the proposed method outperforms traditional control strategies, particularly in terms of handling modeling uncertainties and external disturbances.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144113139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article addresses the distributed state/uncertainty estimation problem for a strict-feedback nonlinear leader system under directed communication topologies. The leader is characterized by Hölder-growing nonlinearities and matched uncertainty. A prescribed-time distributed estimation scheme composed of two distributed extended state observers (DESOs) is proposed. Each follower (observer node) receives only one-dimensional output estimates from its neighbors and at most one-dimensional output from the leader system, effectively reducing the communication load. First, a prescribed-time DESO (PTDESO) is proposed so that each follower can reconstruct the leader's state and uncertainty at a time tightly prescribed by a single parameter, uniform to the initial conditions. Then, a high-gain DESO (HGDESO) is constructed, which achieves asymptotic convergence and maintains the observation errors in a small neighborhood of the origin after the prescribed time. Sufficient conditions for guaranteeing the convergence of the two DESOs are established. Ultimately, practical examples involving multiple manipulators and marine surface vehicles are provided to demonstrate the effectiveness of the proposed observers.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144121668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to conserve the network resources, an adaptive event-triggered approach with network transmission delay is established between the sensor and filter for the decision to release sampled-data. By employing an affine parameter-based membership function, the conservativeness of the filtering model has been relaxed. In contrast to recent results, this approach effectively reduces the communication burden and enhances flexibility in managing sensor failures and disturbances. With the help of the Lyapunov stability theory, a new type of dissipative filtering approach is developed by constructing an asymmetric Lyapunov-Krasovskii functional and using recent integral inequalities in the main results. In particular, the stochastic stabilization criteria are obtained to achieve the weighting matrix and filtering parameters simultaneously by using the linear matrix inequality approach. Two numerical examples, including a tunnel diode circuit, are given to illustrate the merits of the developed approach.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144082913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such an ODE-PDE system arises in many applications such as crane systems with heavy rope and payload. Essentially different from the systems in most of the related literatures, we mainly consider that: (1) the event-triggered tracking control for the cascaded system rather than time-triggered stabilization control, (2) the control input only appears at one end of the ODE rather than directly at the boundary point of the PDE system, (3) the ODE possesses high-order nonlinear and uncertain dynamics rather than linear and deterministic ones. Due to the cascaded system structure and the presence of uncertainty and nonlinearity in the ODE, the input-to-state stable property which is important for the event-triggered control (ETC) is difficult to check. Additionally, how to solve the boundary event-triggered tracking problem for the system remains an open question so far. To this end, by combining the geometric design method, infinite- and finite-dimensional backstepping techniques, an adaptive tracking controller is first constructed. Further, a dynamic event-triggered mechanism is proposed to reduce the actuation frequency. Theoretical proof is rigorously given to show the asymptotic convergence of the tracking error of the PDE controlled output, and the existence of a minimal dwell-time. Finally, a numerical simulation consisting of a crane system in an experimental setting is presented to show the effectiveness of the proposed control scheme.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144121923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

DoS attacks can destroy system access, thereby altering control signals and system dynamics. Although strategies such as zero-input or hold-input have been proposed to mitigate the effects of DoS attacks, these methods are not effective in ensuring immediate update of system control inputs, which has an impact on the overall system performance. To address this challenge, this study proposes a secure predictive control approach for DC microgrid voltage control under two-channel asynchronous DoS attacks. For the two-channel asynchronous DoS attacks, a security transmission scheme that fully utilizes the non-attack time period is designed to achieve timely update of control inputs. Furthermore, by constructing an improved secure controller based on prediction theory and active compensation mechanism, this study effectively compensates the packet loss caused by asynchronous attacks. By combining the secure transmission scheme and the improved secure predictive controller, this study ensures the asymptotic stability of DC microgrids under asynchronous DoS attacks. To verify the effectiveness and performance of the proposed method, this study conducts a series of simulations.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144087118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This limitation reduces their flexibility for application in complex operational scenarios, such as simultaneous attacks on maneuvering targets with specific constraints. To address this limitation, a robust Prescribed-Time Consensus Control (PTCC) is first designed for nominal nonlinear Multi-Agent Systems. Subsequently, a Prescribed-Time State Observer (PTSO) is introduced to derive leader states. Finally, after modeling the relative motion equations within the Line-Of-Sight (LOS) framework, using the proposed PTSO and PTCC approaches, and advanced Sliding Mode Control (SMC), robust guidance laws are presented in the LOS direction and perpendicular to it. These laws ensure that leader and followers simultaneously attack the maneuvering target at the prescribed-time with desired impact angles.

Subsequently, the disturbance compensation term is incorporated into the controller, and a data-driven adaptive proportional-derivative (APD) controller is designed to track the desired signals of yaw angle and position. The introduction of the adaptive mechanism enables real-time parameter adjustment based on system data, effectively eliminating parameter deviations, improving control accuracy, and enhancing the adaptability of controller in complex environments. In addition, the disturbance estimation error is embedded into the closed-loop stability analysis, and the system stability is rigorously demonstrated using Lyapunov theory. Finally, simulation experiments compare the proposed method with improved active disturbance rejection control (ADRC) and FTDO-based continuous terminal sliding mode control (CTSMC).
