The communication topologies are switching among a set of weight-balanced digraphs, and the dynamic of an Euler–Lagrange agent includes unknown parts. In this problem, agents have limited observation of others' states, but agents can estimate other states by exchanging information with their neighbors over switching topologies. The coupling states of agents, uncomplete states, and switching topologies are such that existing distributed control strategies cannot address this problem. In this regard, two distributed controllers are respectively proposed for this game-based distributed control problem with known and unknown dynamics based on the feedback linearization, consensus-based estimation, gradient play, and integral compensation. Based on the time-scale decomposition technique and orthogonal decomposition method, it proves that the proposed controllers can stabilize the Euler–Lagrange agent and are such that the local state is pushed to the Nash equilibrium, and the communication topology is allowed to be arbitrarily switched among different digraphs. Lastly, the simulation demonstrates the effectiveness of proposed controllers.</p>\u0000 </div>","PeriodicalId":50291,"journal":{"name":"International Journal of Robust and Nonlinear Control","volume":"35 5","pages":"1870-1879"},"PeriodicalIF":3.2,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143380152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 principal concept is to construct a high-level Markovian process governed controller under an asynchronous event-triggered scheme and to develop a time-varying dissipative index. As a salient feature that distinguishes it from the reported works with the common index, this paper firstly proposes a dissipative index with mode and membership functions-dependence. Secondly, governed by the high-level Markovian process, the asynchronous dynamic output feedback controller is constructed under the mode-dependent partitioned regions. Meanwhile, to mitigate the communication pressure, an asynchronous dynamic event-triggered mechanism is investigated with making allowances for the inaccessible system mode. What's more, as a first effort, this article presents a unified framework for co-designing the strategy of asynchronous event generators and controllers. This is done under the proposed performance index and the mode-dependent fuzzy state-space partitions, resulting in more design flexibility. Based on the mode and region-dependent Lyapunov functional, sufficient criteria are obtained to ensure the proposed dissipative performance and stochastic stability. Eventually, the practicabilities and advantages of the theoretic results are illustrated by a modified tunnel diode circuit model.</p>\u0000 </div>","PeriodicalId":50291,"journal":{"name":"International Journal of Robust and Nonlinear Control","volume":"35 5","pages":"1809-1821"},"PeriodicalIF":3.2,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143380449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 system is known to be stabilizable by the static output-feedback employing several distributed in space actuators and sensors, but is not stabilizable by only one of the actuator-sensor pairs. Does there exist a switching stabilizing static output-feedback such that at all times, only one actuator-sensor pair is active? In our recent paper we gave a positive answer and found the appropriate switching sampled-data time-triggered control law for the one-dimensional (1-D) case. In this paper, to enlarge the time between switching (which means to reduce the frequency of actuator moving to the active domain), we present an event-triggered control for stabilization by switching. Moreover, we extend the results for stabilization by switching to the N-D case.

Our criteria reveal the negative effect of AIDG on synchronization, which hinders the synchronization process. Additionally, we refine the concept of average impulsive gain to enhance its applicability.
