Distributed Resilient Fixed-Time Control for Cooperative Output Regulation of MASs over Directed Graphs under DoS Attacks
It addresses the problem of resilient fixed-time control for multi-agent systems under DoS attacks, relaxing assumptions of Laplacian symmetry and strong connectivity, which is an incremental improvement over existing methods.
This paper develops a distributed resilient fixed-time controller for cooperative output regulation of linear multi-agent systems under DoS attacks over directed graphs, achieving convergence to zero in a fixed time independent of initial states.
This paper addresses the problem of fixed-time cooperative output regulation for linear multi-agent systems over directed graphs under denial-of-service attacks. A novel distributed resilient fixed-time controller is developed that comprises a distributed resilient fixed-time observer taking general directed graphs into consideration, and a distributed resilient fixed-time control law for each agent. The proposed controller neither depends on Laplacian symmetry nor requires strong connectivity and detail-balanced condition, in contrast to existing distributed resilient fixed-time controllers. Under the proposed controller, the regulated outputs converge to zero in a fixed time with its upper bound independent of the initial states of the multi-agent system. Ultimately, the efficacy of the proposed controller is demonstrated via a simulation example.
