Model-Based Dynamic Event-Triggered Distributed Control of Linear Physically Interconnected Systems and Application to Power Buffers

We study the model-based dynamic event-triggered distributed control for linear physically interconnected systems. For each subsystem, a distributed event-triggered control law, along with a model-based dynamic event-triggering mechanism, is proposed. The resulting closed-loop system is shown to be exponentially stable. A positive minimum interevent time excludes the Zeno behavior for each subsystem and is shown to be larger than the one guaranteed by the conventional zero-order-hold approach. Numerical studies on coupled inverted pendulums and experimental results on networked power buffers validate the proposed methodology.
