Jing He, Dongsheng Yang, Jiayue Sun, Juan Zhang, Chengyun Li · IEEE Transactions on Cybernetics · 2025
This article addresses a new type of adaptive time-varying group formation tracking (TVGFT) problem for linear multiagent systems (MASs) with nonautonomous leaders. To fulfill complicated formation tasks, a TVGFT protocol is proposed, where the agents are decomposed into multiple subgroups and each subgroup can successfully track the corresponding leader. Additionally, novel multiple asynchronous dynamic edge-event-triggered mechanisms (DEETMs) are designed to further conserve communication resources and optimize network utilization by enabling the leader to send information intermittently and allowing each follower to transmit information asynchronously when the trigger mechanisms are satisfied. The DEETMs consider both interlayer and intergroup information interactions to improve communication efficiency. Different from the existing results, the proposed DEETMs are used for intergroup information exchange to enhance both the coordination of formation and information transparency. At last, the simulation experiment is offered to validate the designed protocol.
