This paper presents a novel integrated framework for hybrid attacks that consists of aperiodic DoS attacks, deception attacks, and replay attacks. To minimize continuous data transmissions in the network and maximize the utilization of limited resources, an adaptive periodic event-triggered mechanism (APETM) is developed by employing the DoS-dependent adaptive varying threshold. Compared to common event-triggered mechanisms, this method allows for periodic monitoring and effectively increases the lower bound of event intervals, making it well-suited for real-world applications. Initially, a new theoretical framework for cyber-physical systems is proposed, incorporating an adaptive periodic event-triggered mechanism under hybrid cyber-attacks, external disturbances, and actuator faults. Based on the established model, the Lyapunov-Krasovskii stability theory is employed to establish sufficient conditions for ensuring the finite-time stability with an H∞ performance level. Additionally, a linear matrix inequality technique is utilized to determine the controller gains and triggering parameters. The effectiveness of the proposed method is demonstrated through a simulation of the one-link flexible joint robot systems.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144082895","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 paper presents a new control method to handle the stability problem of a cart-type inverted pendulum. The system is divided into two second-order subsystems: an inner-layer dynamic system of the rod and an outer-layer dynamic system of the cart. Then a simultaneous planning and executing (SPAE) control method based on double-layer polynomial planning is proposed to make the inner-layer and outer-layer systems asynchronously converge in different time intervals. To achieve this asynchronous convergence, the outer-layer system adjusts the cart displacement. Its goal is to provide a smooth reference angle. The inner-layer system should track this angle quickly and precisely. In contrast to existing control approaches, the proposed method does not require parameter optimization or an accurate nonlinear model. Simulated and experimental results have verified that the proposed control method can achieve the double-layer asynchronous convergence in different time intervals, indicating its superiority over other feedback control approaches.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144082951","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}

Improving the disturbance rejection capability of EML systems is crucial for ensuring safe and stable train operation. To address this challenge, this paper proposes an active resisting disturbance control method with weak model dependence, combining model reference adaptive control (MRAC) and active disturbance rejection control (ADRC). First, MRAC is used to approximate the plant to the reference model to avoid problems caused by model uncertainty. Then, a linear extended state observer (LESO) is constructed based on nominal model parameters to estimate and compensate for disturbances. Additionally, a tracking differentiator (TD) is incorporated to extract system states for constructing the MRAC law. The Lyapunov stability theory is used to prove that the EML system can achieve stability under the proposed control law. Finally, the simulation experiment and physical verification experiment are designed. The experimental results show that the proposed control method outperforms PID, SMC, and ADRC in disturbance rejection and its control performance is insensitive to the changes in model parameters and equilibrium point.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144087111","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}

We first focus on asymptotic stabilization using a Lyapunov-based control law, referred to as the \"unsafe control\", and introduce an additional state variable alongside a \"safeguarding control\" to guarantee safe operation of the closed-loop system. The proposed closed-form scheme limits the impact of the safeguarding control on the functionality of the closed-loop system, ensuring the derivative of a control Lyapunov function remains at least negative semi-definite. User-defined parameters provide flexibility in managing safety constraints, while the method's adaptability allows for integration with existing control techniques. Furthermore, we extend our results to robust safety control for nonlinear systems subject to external disturbances, ensuring both safety and input-to-state stability. In addition to theoretical developments, the effectiveness of the proposed controllers is validated through three comprehensive case studies, demonstrating their potential in real-world applications. The results highlight the controllers' ability to maintain safety and stability without the computational burden of real-time quadratic programming, thereby enhancing their suitability for systems with fast dynamics.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144082948","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}

FIT-GSTM combines an inverted Transformer with a Spatiotemporal Graph Convolutional Network (STGCN) to effectively capture global spatiotemporal dependencies across multi-sensor data. To further enrich feature representation, the model incorporates Fast Fourier Transform (FFT) to extract frequency-domain information and fuses it with time-domain features, enhancing robustness to noise. Additionally, the integration of Memory Tokens and Reversible Instance Normalization (RevIN) strengthens the model's ability to retain long-term dependencies and adapt to heterogeneous data distributions. Experimental evaluations on the C-MAPSS dataset demonstrate that FIT-GSTM achieves superior RUL prediction accuracy and generalization compared to existing methods, highlighting its potential for real-world deployment in aeroengine health management.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144046301","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}
