Summary:The present paper focuses on the bounded consensus problem of multi-agent systems (MASs) with external disturbances. A novel hybrid dynamic event-triggered mechanism (DETM) is proposed to simultaneously reduce the triggering frequency of the sensors and controllers. Under this mechanism, a fully distributed event-triggered protocol is designed to reach the bounded consensus. Not only the triggering functions but also the control protocols utilize the relative information between agents and are independent of the global information of the system network. Furthermore, the Zeno phenomenon is excluded for any time. In comparison with existing results, the most significant advantage of this paper is that the designed hybrid DETM reduces both the communication frequency between agents and the controller update frequency. Finally, several examples are introduced to validate the effectiveness and advantages of the proposed methods.
