Distributed event-triggered consensus control for multi-agent systems under independent DoS attacks: A randomized transmission approach

Abstract

In this article, the consensus problem for disturbed multi-agent systems (MASs) under independent denial-of-service (DoS) attacks is investigated. The concerned attacks can jam different channels independently, resulting in a time-varying and unknown network topology. In this situation, a dynamic event-triggered control scheme with a hybrid communication strategy is presented to schedule information interaction over the network, and a distributed prediction-based control algorithm is proposed to ameliorate the resilience. The system stability is proved in present of DoS attacks by introducing the decay rates of Lyapunov functions associated with different connectivity modes. In comparison with the most existing MASs studies under DoS attacks, the triggering mechanism that possibly subject to the malicious attacks executed at the triggering times is protected by the proposed randomized transmission protocol, and the tolerable attack intensities are quantified. Finally, simulations are presented to substantiate that the proposed strategy is effective.
