Dynamic event‐triggered consensus control of multiagent systems under DoS attacks with intermittent communication

This paper addresses the dynamic event‐triggered consensus problem of multiagent systems (MASs) under denial‐of‐service (DoS) attacks within an intermittent communication framework. First, a Lyapunov‐based intermittent scheduling rule is introduced, enabling the controller to dynamically adjust activation and idle times according to the current system state, thus facilitating flexible allocation of communication and control resources. Second, a dynamic event‐triggered communication (DETC) scheme is designed to reduce the communication frequency within the network, thereby preventing continuous communication among agents. Additionally, through the introduction of DoS attack intervals and by leveraging Lyapunov functions and attack frequency analysis, it is proven that MASs can achieve secure consensus under this framework. Furthermore, the proposed event‐triggered scheme eliminates Zeno behavior, ensuring its practical feasibility. Finally, simulation results validate the effectiveness and practicality of the proposed intermittent communication mechanism combined with the event‐triggered control strategy.
