This article addresses the cooperative output tracking problem of a class of linear minimum-phase multiagent systems with unknown and heterogeneous agent dynamics. A distributed event-triggered model reference adaptive control strategy is developed, which ensures synchronization of outputs among all agents to the leader's output while excluding Zeno behavior. The proposed adaptive control strategy is fully distributed and does not require any prior global information.
This article addresses the cooperative output tracking problem of a class of linear minimum-phase multiagent systems, where the agent dynamics are unknown and heterogeneous. A distributed event-triggered model reference adaptive control strategy is developed. It is shown that under the proposed event-triggered control strategy, the outputs of all the agents synchronize to the output of the leader asymptotically. It is also shown that Zeno behavior can be excluded with the proposed novel event triggering mechanism. In addition, the proposed adaptive control strategy is fully distributed in the sense that no prior knowledge of some global information, such as the eigenvalues of the associated Laplacian matrix and the number of the agents is required. Finally, an example is given to demonstrate the effectiveness of the proposed control strategy.
