Initially, the considered nonlinear system is reconstructed via the Takagi–Sugeno fuzzy rule. Then, to simultaneously realize the observation and control of the spacecraft surface temperature, an observer-based point controller is proposed in terms of averaged measurements. In addition, taking the network congestion issue into consideration, a spatiotemporal event-triggered mechanism and a quantization method are adopted to reduce data transmission and enhance bandwidth utilization. Furthermore, to resist cyberattacks and actuator faults, a fuzzy resilient control strategy is designed to ensure the stability of the closed-loop system with <span data-altimg=\"/cms/asset/207739ec-af4a-4568-8a88-d1846404b051/asjc3472-math-0001.png\"></span><mjx-container ctxtmenu_counter=\"0\" ctxtmenu_oldtabindex=\"1\" role=\"application\" sre-explorer- style=\"position: relative;\" tabindex=\"0\"><mjx-lazy aria-hidden=\"true\" data-mjx-lazy=\"0\"></mjx-lazy><mjx-assistive-mml display=\"inline\" unselectable=\"on\"><math data-semantic-=\"\" data-semantic-role=\"unknown\" data-semantic-speech=\"\" data-semantic-type=\"empty\" xmlns=\"http://www.w3.org/1998/Math/MathML\"></math></mjx-assistive-mml></mjx-container> disturbance attenuation performance.

Firstly, a framework is introduced involving N players, where player 1 and player N form a zero-sum (ZS) game, and player 1 and players 2 to N-1 form nonzero-sum (NZS) games, with some players experiencing time delays. Subsequently, the system's value function is augmented with a control barrier function (CBF) to ensure that the system's state remains within a safe region. Secondly, to approximate Nash equilibrium solutions, the study employs adaptive dynamic programming (ADP) and utilizes a critic-only neural network (NN) to approximate optimal solutions. Diverging from traditional time-trigger methods, computational and communication load reduction is achieved by introducing a state-related event trigger condition. The stability of the system is then meticulously analyzed using the Lyapunov theorem. Finally, to validate the effectiveness of the proposed method, the study provides a simulation example demonstrating its performance. In summary, this research introduces an efficient adaptive safety control method for addressing multiplayer MZS games with partial inputs delay, incorporating CBFs, ADP, and state-related event triggering.</p>","PeriodicalId":55453,"journal":{"name":"Asian Journal of Control","volume":"27 1","pages":"488-504"},"PeriodicalIF":2.7,"publicationDate":"2024-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141737606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiple load conditions are simultaneously considered. To complete the tracking control task and enhance the power quality under different loads, a composite control scheme, which contains two parts, is proposed. In the first part, two finite‐time disturbance observers are established to estimate the mismatched multiple disturbances originating from load variations. In the second part, new integral‐type sliding‐mode surfaces embedding disturbance estimates and ‐axis couplings are designed, which not only feedforward compensate for the disturbances but also achieve decoupling. Based on the sliding‐mode surfaces, a composite controller is constructed. Compared with the existing results, the proposed controller is continuous and significantly reduces chattering. Moreover, with the novel decoupling strategy, the ‐axis coupling problem is solved precisely without generalizing the couplings as disturbances, which simplifies the observation task and further accelerates system convergence. Rigorous stability analysis is conducted to demonstrate the accomplishment of the finite‐time tracking task. Simulations and experiments are presented to validate the effects of the proposed control scheme.","PeriodicalId":55453,"journal":{"name":"Asian Journal of Control","volume":"35 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141737607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The DL theory is utilized to satisfy the partial persistent excitation condition, while the AHGO is employed to estimate the system states and fault functions simultaneously. Two DETMs are adopted to reduce data transmission and computational burden. The inter‐event intervals of the considered event‐triggered mechanisms are proven to be positive, thus excluding the Zeno phenomenon. The novelty of this paper lies in that, through the special design of AHGO and event‐triggered conditions, the estimation errors can converge to zero with arbitrary precision. Meanwhile, by incorporating the estimated output error into the DETM design, it is demonstrated that the number of events can be adaptively adjusted based on the fault signal. Furthermore, the relationship between the observer gain and system performance, as well as the inter‐event interval, is revealed (The event‐triggered mechanisms design method that ensures exponential convergence of the observer). Finally, the effectiveness of the developed strategy is verified through a simulation example.","PeriodicalId":55453,"journal":{"name":"Asian Journal of Control","volume":"39 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141613814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A bank of H−/L∞ unknown input observers (UIOs) is established using the generalized observer scheme to generate residuals that are insensitive to a specific actuator fault but sensitive to the other actuator faults. Furthermore, in the finite‐frequency domain, the H− and L∞ performance indices are simultaneously used to improve the fault detection sensitivity and attenuate the influence of disturbances on the residuals, respectively. The design conditions for the bank of H−/L∞ UIOs are derived from the generalized Kalman–Yakubovich–Popov lemma and converted into an optimization problem constrained by linear matrix inequalities to solve the design matrices more easily. To diagnose actuator faults, a fault detection and isolation scheme is established using the time‐varying threshold from the L∞ performance analysis. Finally, the effectiveness of the fault detection and isolation scheme using the bank of H−/L∞ UIOs is validated by the simulation of two examples.","PeriodicalId":55453,"journal":{"name":"Asian Journal of Control","volume":"29 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141613813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
