Event-Triggered Consensus Control of Multi-Agent System under Periodic DoS Attacks

The consensus control problem for the multi-agent system (MAS) against periodic Denial-of-Service (DoS) attacks is focused on in this paper. The characteristic of periodic DoS attacks is that the attack duration is fixed, and the attack start time of each attack is periodic. Considering arbitrary periodic DoS attacks under a communication topology, a resilient controller with a switching mechanism is proposed by using the present and delayed neighbor information. Besides, an event-triggered mechanism (ETM) is designed to adjust the controller triggering frequency according to the periodic DoS attacks. The consensus and convergency of MAS against periodic DoS attacks are theoretically analyzed via Lyapunov stability criteria. Numerical simulations are provided to demonstrate the effectiveness of the proposed method.
