Abstract:An individual-based distributed controller is designed for first-order multi-agent systems with input delay,unknown disturbances and switching topology.Under two different dynamic event-triggered control protocols,the sufficient conditions for the system to solve the practical fixed-time average consensus problem are given respectively,and it is proved that there is no Zeno behavior in the system.Among them,the dynamic event-triggered control protocol with continuous communication can make triggering condition change in real time by introducing internal dynamic variable,which significantly reduces the number of individual triggering,the frequency of controller updates and the overall energy consumption of the system,the dynamic event-triggered control protocol with intermittent communication only needs to use the neighbor information at the triggering instant and the estimated value of the internal dynamic variable,which avoids the continuous communication between individuals,effectively reduces the communication burden of the system and saves the communication resources.Numerical simulation results verify the effectiveness of the proposed control protocols.
