Secure Consensus Control of Multi-Agent System Under DoS Attacks

Abstract

This paper studies the distributed secure consensus of multi-agent system under denial-of-service attacks, which are classified into four modes based on the different post-attack network topologies. Then, a new attack sequence is established, which permits multiple attacks with different modes to be launched after a sleep period. Subsequently, a distributed control scheme is constructed and the control gains are related to the attack modes to reduce conservatism. Furthermore, by utilizing the Lyapunov method and iterative techniques, sufficient conditions are derived to ensure the achievement of secure consensus in the multi-agent system. Finally, simulation results are presented with robotic manipulators to validate the feasibility of the proposed control scheme.
