Abstract : This work addresses the memory event-triggered consensus control design problems of multi-agent systems (MASs) under actuator failures and aperiodic denial-of-service (DoS) attacks. In order to overcome an unpredictable traffic in the network communication channel, an appropriate memory event-triggered scheme (METS) is proposed. The purpose of this scheme is to utilize certain release packets to create new event compared with the existing event-triggered scheme (ETS). In this fashion, the event generator can achieve accurate decision as well as better performance of the control can be expected. Further, a new switched approach is established to describe the consensus performance of system model with aperiodic DoS attacks. By incorporating the Lyapunov-Krasovskii functional (LKF), adequate constraints of the consensus for MASs are derived. Based on the obtained conditions, the consensus control gain matrices are presented by utilizing the technique of linear matrix inequalities (LMIs). Eventually, simulation results are given to validate the applicability of the proposed theoretical results which is based on the F-18 aircraft model systems.
