Fully distributed dynamic event-triggered consensus control for multi-agent systems under DoS attacks

Abstract

This article focuses on the event-triggered fully distributed consensus control for linear multi-agent systems (MASs) under DoS (denial of service) attacks. A dynamic event-triggered mechanism (DETM) relying on measurement error and dynamic parameter is proposed to alleviate the problem of limited network bandwidth. To defend against DoS attacks, a switching strategy is adopted to design the fully distributed consensus protocol. By analyzing with Lyapunov-Krasovskii functional, the asymptotic stability conditions (i.e., the consensus of MASs is solved under DoS attacks) of the consensus error model are obtained in terms of LMIs. The derived results indicate that our proposed control strategy successfully realize the fully distributed secure average consensus(SAC) of MASs without requiring global information. Moreover, Zeno behavior of the proposed DETM is proved to be excluded. Finally, a numerical simulation is provided to verify the validness of our method.
