Event-Based Containment Control for Homogeneous/Heterogeneous Multi-Agent System Under Aperiodic Dos Attack

Abstract

The containment problem of multi-agent system (MAS) under a class of aperiodic denial-of-service (DoS) attack is discussed. Based on switching theory, the system subject to DoS attack is modeled as a new model containing closed-loop and open-loop subsystems. Aiming at the homogeneous MAS, a distributed event-triggered strategy and a state feedback controller are proposed to realize the state containment. Subsequently, it is demonstrated that the triggering condition proposed in this paper can avoid Zeno behavior. Furthermore, for heterogeneous MAS, containment control in the attack environment is investigated based on output regulation theory. The leaders are treated as reference system, and an output feedback controller is proposed that relies on the observed state and reference system state. Finally, simulation examples of homogeneous and heterogeneous MAS are provided to verify the effectiveness of the results.
