Distributed Event-Triggered Observer-based Control for Linear Networked Multi-Agent Systems

This paper studies the distributed event-triggered observer-based control problem for linear multi-agent systems with heterogeneous dynamics and external disturbances. In particular, the multi-agent system and its observers communicate via multiple independent and asynchronous networks, the observers can communicate with each other, and each controller is designed via the corresponding observer. In such a framework, we first investigate the information transmission in the closed-loop system, then apply local information to develop distributed event-triggered mechanisms, and finally derive sufficient conditions for the co-design strategy to ensure the desired performance. Further discussions are presented to show the generality of the proposed framework. A numerical example from power systems is presented to illustrate the derived results.
