Impulsive Synchronization Control for Multiagent Systems Under Hybrid Attacks

This article investigates the secure impulsive consensus of multiagent systems (MASs) under different cyber-attacks. Owing to the coupling between false data injection (FDI) attacks and denial of service (DoS), investigating secure impulsive control for MASs presents significant challenges. The stability of MASs is analyzed separately under DoS and FDI attacks. It provides sufficient conditions for MASs to achieve almost sure consensus under DoS attacks and provides adequate conditions to ensure mean-square bounded synchronization under FDI attacks. Furthermore, by considering the coupling of two types of cyber-attacks, the article provides adequate conditions to achieve synchronization of the system under hybrid attacks. The article designs impulsive controllers for FDI, DoS, and hybrid attacks to achieve secure impulsive control. Finally, an MAS with five followers is considered, and the validity of the three devised impulsive controllers is confirmed via simulation experiment.
