Synchronization of linear high-order heterogeneous multi-agent systems via event-triggered control with limited output communication

Abstract

In this paper we consider the output synchronization problem for linear high-order heterogeneous multi-agent systems with a directed communication graph. A distributed event-triggered control protocol is provided to solve the problem. The protocol is applicable to different agents, even with different dimensions. It is worth mentioning that the protocol only requires each agent to send the output information which are to be synchronized when an event-triggered condition is satisfied. Such a control protocol substantially reduces the cost of communication. The proposed protocol also ensures that the synchronization of the multi-agent system can be achieved asymptotically without Zeno-behavior. A numerical simulation is presented to illustrate the effectiveness of our protocol.
