Abstract：This paper investigates the event-triggered control problem for direct-current(DC)microgrids with denial-of-service(DoS)attacks.Considering the fact that the states of DC microgrids cannot be always measurable,an observer is designed to estimate the states of DC microgrids.Based on observer states,a novel attack-resilient event-triggered controller is designed for DC microgrids under DoS attacks.The proposed controller design method can be converted into a convex problem by proposing an improved separation method.Besides,the Zeno behavior is also discussed and eliminated in the designed event-triggered mechanism by using the contradiction method.Finally,a practical microgrid example is shown to illustrate the effectiveness of the proposed control scheme.
