Event-triggered Leader-following Consensus Control of Multiagent Systems Against DoS Attacks

This paper addresses the issue of secure leader-following consensus for multiagent systems (MASs) under denial-of-service (DoS) attacks. In such attacks, the communication channels of agents may be disrupted until the attack terminates. To tackle this challenge, first, an event-triggered communication (ETC) scheme is proposed to alleviate unnecessary information transmission in energy-limited and easily attackable networks. Then, the concept of effective DoS attack intervals is introduced, and the duration attack length rate is analyzed. By employing a Lyapunov function and the average dwell-time (ADT) method, the secure consensus can be achieved. Moreover, Zeno behavior is eliminated to ensure the feasibility of the event-triggered scheme. Finally, simulation results are provided to validate the effectiveness of the proposed update strategy and control protocol.
