Secure Adaptive Sampling Event-Triggered Control of Multi-Agent Systems Under DoS Attacks

In this paper, we investigate the consensus problem of linear multi-agent systems (MASs) under denial-of-service (DoS) attacks using a novel adaptive sampling dynamic event-triggered control (ASDETC). Firstly, we introduce an estimator under DoS attack situation, and through this estimator, we design a dynamic event-triggered communication protocol, effectively avoiding the issue of continuous communication between agents. Then, a detection algorithm is proposed to enable each agent to adjust its sampling detection interval adaptively based on the frequency of event triggering. Using Lyapunov analysis, it is demonstrated that ASDETC can effectively drive the MASs toward exponential consensus, provided that the DoS attacks satisfy a condition on frequency and duration.
