Abstract

This paper investigates secure semi-global bipartite consensus (SSGBC) of linear multi-agent systems (MASs) with input saturation under denial-of-service (DoS) attacks via dynamic event-triggered control (DETC). A distributed DETC protocol is proposed for avoiding redundant information transmission. Subsequently, by utilizing Lyapunov stability theory and a low-gain feedback based bipartite consensus algorithm, it is proved that SSGBC of linear MASs can be achieved under the proposed DETC protocol under the assumption that the frequency and the duration are limited. Moreover, Zeno behavior of each follower can be excluded. Finally, a simulation example is given to verify effectiveness of the proposed DETC protocol.

Keywords Denial-of-service (DoS) attacks, dynamic event-triggered control (DETC), input saturation, multi-agent systems (MASs), secure semi-global bipartite consensus (SSGBC).
