Event-Triggered Guaranteed Cost Secure Consensus Control of Multi-Agent Systems Under DoS Attacks Over Multiple Communication Channels

This paper investigates the distributed event-triggered guaranteed cost secure consensus for linear multi-agent systems (MASs) subject to denial-of-service (DoS) attacks over multiple communication channels. First, a classification strategy is proposed, which categorized the multi-channels DoSs attacks as three attack modes according to the attack strength. Second, an event-triggered controller is constructed for reaching the secure consensus, which can simultaneously reduce computation/transmission resources and attenuate the impact of attack. The corresponding feedback gains are designed for each attack modes to reduce conservatism in control and analysis. Furthermore, to explore the trade-off between secure consensus regulation performance and control energy consumption, an event-triggered guaranteed cost consensus criterion is established by exploiting the joint effect of state errors among neighboring agents and control inputs. Particularly, the determined upper bound of the cost function depends merely on the initial conditions of the agents. Finally, simulation results are given to validate the proposed control scheme.
