Fully distributed event-triggered consensus control for linear multiagent systems under DoS attacks

This article investigates the event-triggered consensus problem of general linear multiagent systems with denial-of-service (DoS) attacks. A distributed event-triggered mechanism is presented to alleviate the limited communication resources, the designed mechanism is fully distributed owing to the introduction of some adaptive parameters. Moreover, since the DoS attacks have been considered in the event-triggered rule design, a switching strategy for the adaptive parameters is adopted. A switching Lyapunov function is used to strictly demonstrate that secure consensus can be reached effectively under the proposed control mechanism. The quantitative relationship between the frequency of the DoS attacks and the consensus is also presented. Moreover, the Zeno behaviour can be excluded for the studied close-looped systems. Finally, a numerical simulation example is given to demonstrate the validity of the designed control law.
