Within the scope of application and of practical relevance is the enhancement of the region of attraction for which equilibrium states are found for an electric vehicle (EV) charging station while considering constraints. As a main contribution, a methodology for the design of the cubic controller to expand the constrained region of attraction (CROA) through sum-of-squares (SOS) programming is formulated, implemented, and validated. The developed SOS program incorporates the construction of Lyapunov functions, which are employed to estimate the CROA. The optimal coefficient of the cubic controller is obtained by estimating the largest CROA. The integration of the cubic controller enhances the robustness of the EV charging station against large disturbances, while the performance under minor disturbances is dealt with by the accompanying PI controller. As a result, the proposed PI-cubic voltage controller enhances the stability across wide operating ranges including fast charging and in the presence of constant power loads. In general, application also includes DC microgrid stability. Time-domain simulations conducted in Matlab validate the made claims. During the considered outage of local power generation on the DC side of the charging station and microgrid, transient stability was only maintained with the proposed controller, and an overcurrent situation was avoided. The PI-cubic controller is shown to be effective in enhancing robustness.","PeriodicalId":13039,"journal":{"name":"IEEE Transactions on Circuits and Systems I: Regular Papers","volume":"72 7","pages":"3669-3682"},"PeriodicalIF":5.2,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11061814","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144557584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work presents an integrated interface circuitry for triboelectric generators (TEGs) where rectification and regulation are combined in a single stage which minimizes the number of charge transfer stages and power losses in the front-end diode bridge rectifiers and thus results in improved efficiency. The proposed circuit also addresses the issue of the asymmetric TEG output during the positive and negative half-cycles. It performs active rectification of the low amplitude alternating current output generated during the negative half-cycle, corresponding to the release cycle of the device. The proposed circuit is designed and fabricated using 180nm CMOS BCD process. The experimental characterization of the fabricated integrated circuit (IC) is conducted by interfacing it with in-house fabricated TEG device. The developed harvesting system demonstrates an energy conversion efficiency of 75.6%. Overall, the proposed single-stage interface circuit presents a compelling alternative to the conventional two-stage interfacing approach in terms of simplicity, reliability, robustness and potentially lowered costs and power consumption. Additionally, the system supports cold start-up without an external power supply.","PeriodicalId":13039,"journal":{"name":"IEEE Transactions on Circuits and Systems I: Regular Papers","volume":"72 12","pages":"8482-8491"},"PeriodicalIF":5.2,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145600695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An FTDO with time-varying observer gains is initially developed to reconstruct the lumped perturbations caused by external disturbances, parameter uncertainties, and actuator faults. A fixed-time auxiliary system is employed to counter the adverse effects of actuator saturation. Additionally, asymmetric prescribed performance and shift functions are skillfully incorporated to handle arbitrary bounded initial conditions. Subsequently, a novel FTDO-based event-triggered STPC strategy is formulated, ensuring that attitude-tracking errors converge to predefined performance bounds within a predetermined time while minimizing unnecessary control signal updates. The practical fixed-time stability of all closed-loop signals is validated, with the strict avoidance of Zeno behavior. Finally, simulation studies are conducted to verify the accuracy and effectiveness of the proposed approach.","PeriodicalId":13039,"journal":{"name":"IEEE Transactions on Circuits and Systems I: Regular Papers","volume":"72 12","pages":"8408-8420"},"PeriodicalIF":5.2,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145600711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By designing state observers, the problem of unmeasurable states is addressed. The key to non-overshooting control (OC) is how to design appropriate controller to ensure the system is not only stable but also effectively solves the non-OC problem. Based on backstepping, a square root gain control algorithm is proposed in this paper, which ensures global asymptotic stability of the closed-loop system. Meanwhile, two main conclusions are drawn in non-OC: 1) If the initial values of the system states are equal to the initial values of the observer states, the conditions obtained by the proposed algorithm can achieve non-OC, i.e., the system overshoot is zero. Non-OC conditions for <inline-formula> <tex-math>$n=1$ </tex-math></inline-formula>, <inline-formula> <tex-math>$n=2$ </tex-math></inline-formula>, <inline-formula> <tex-math>$n=3$ </tex-math></inline-formula>, and <inline-formula> <tex-math>$ngeq 4$ </tex-math></inline-formula> order systems are obtained, respectively. And the conditions are relatively rich. Therefore, compared with existing algorithms, this algorithm not only ensures zero system overshoot, but also reduces conservatism; 2) If the initial values of the system states are not equal to the initial values of the observer states, the conditions obtained by this algorithm can achieve mean-non-OC, i.e., the system overshoot can be adjusted to any small value. In terms of simulation, the stability performance algorithm, non-OC algorithm, and mean-non-OC algorithm were verified using the mathematical models of the DC servo motor systems and Chua’s circuit system. Simulation results show that these control algorithms are effective. It also compares existing related results, highlighting the superiority of the algorithm presented in this paper.","PeriodicalId":13039,"journal":{"name":"IEEE Transactions on Circuits and Systems I: Regular Papers","volume":"72 12","pages":"8383-8395"},"PeriodicalIF":5.2,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145600706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a reinforcement learning-based dual-channel dynamic event-triggered fixed-time load frequency control approach for uncertain multi-area power systems with input delays. A non-singular fast terminal sliding mode technique is employed to guarantee that the tracking error converges within a fixed time. To address system uncertainties and input delays, actor neural networks are designed to estimate the modeling uncertainties and provide compensation, and critic neural networks evaluate execution costs. To further enhance efficiency, a dual-channel event-triggered mechanism is designed, reducing communication overhead through independent dynamic event-triggering strategies for control input and output channels. The stability of the proposed method is rigorously analyzed using the Lyapunov method. Simulation results demonstrate faster convergence, reduced communication costs, and improved frequency stability compared to existing methods.","PeriodicalId":13039,"journal":{"name":"IEEE Transactions on Circuits and Systems I: Regular Papers","volume":"72 12","pages":"8492-8504"},"PeriodicalIF":5.2,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145600668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these issues, this paper proposes a synergetic learning-based decentralized secure tracking control scheme for nonlinear interconnected systems with multiple actuator faults. Replacing actual states with desired ones in the coupled system relaxes the assumption of requiring a known upper bound for interconnections, and a neural network observer is designed to estimate the replaced interconnections. To reduce fault-tolerant delays, the secure tracking control problem is reformulated as an adversarial evolution problem between fault signals and control inputs, eliminating the need for fault compensation. To achieve optimal tracking control, an augmented subsystem is constructed by integrating the dynamics of tracking error and the reference trajectory. A modified cost function is designed for the augmented subsystem, and a critic network with two cooperative updating laws is developed to solve the Hamilton–Jacobi–Isaacs equation, providing a synergetic approximate solution for the control input and fault assistance signal. It is proven that the tracking error converges to a small neighborhood of the equilibrium. Simulation results demonstrate the effectiveness of the proposed approach.","PeriodicalId":13039,"journal":{"name":"IEEE Transactions on Circuits and Systems I: Regular Papers","volume":"72 12","pages":"8370-8382"},"PeriodicalIF":5.2,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145600698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
