Adaptive Event-Triggered $H_{\infty}$ Consensus of Leader-Following Multi-Agent Systems Under Hybrid Random Cyber Attacks

The
$H_{\infty}$
consistency control problem of leader-follower multi-agent systems (MASs) under hybrid random cyber attacks is investigated in this article based on the adaptive event triggering mechanism. For the first time, the exposure of each agent to hybrid random cyber attacks and external disturbances is considered simultaneously, an appropriate adaptive event triggering control protocol is designed. Meanwhile, considering the impact of time lag on system consistency, by converting the leader-following error system into a time-delay error system and using the Lyapunov-Krosovskii functional technique, the sufficient conditions for the system's
$H_{\infty}$
exponential stability are deduced. Lastly, numerical simulation is used to confirm the control protocol's superiority and effectiveness.
