Event-triggered control for cooperative output regulation of linear multi-agent systems based on multi-order neighbours' information

This is the authors' abstract. We don't add key points for this paper.

In this paper, we consider the cooperative output regulation problem of heterogeneous linear multi-agent systems. In order to save communication resources, we establish a new event-triggered dynamic output feedback control protocol by utilising multi-order neighbours' information. For each agent, the proposed control law is composed of a local observer-based feedback term and a distributed feedforward term. The key novelty lies in the update law of the dynamic controller's state, which explicitly incorporates multi-order neighbours' information. Through quantitative analysis of convergence acceleration, we rigorously prove that the control law using higher-order neighbours' information will accelerate the convergence rate of the tracking error. Moreover, the number of event triggers is also reduced accordingly. Finally, an example is used to verify the effectiveness of the results.
