Conclusions
In this paper, the problem of distributed consensus control for MASs under DoS attacks has been investigated. While the adversaries compromise each channel independently, various attack modes have been considered. Based on the proposed distributed state-feedback and observer-based controllers, the decay rates under different attack modes are obtained by solving LMIs. Besides, a novel scaling method has been proposed to reduce the computational complexity at the cost of introducing some conservatism. Then, based on the obtained decay rates, sufficient conditions on the duration of DoS attacks, under which the stability isstill guaranteed, have been proposed. It is shown that under the proposed distributed statefeedback and observer-based controller, the consensus is achieved despite the DoS attacks satisfying the proposed conditions. For future work, we can extend the proposed results for event-triggered consensus [6], and such problem is challenging for that whether the event is triggered may be unknown for the existence of DoS attacks.
