Event-Triggered Decentralized Dynamic Output Feedback Control for LTI Systems*

In this paper we investigate event-triggered controllers for dynamic output feedback control of Linear Time Invariant (LTI) systems. We propose a systematic methodology for designing implicitly verified event-triggered dynamic output feedback controllers for LTI systems that are observable and controllable. Event-triggering conditions for sampled-data implementation of the observer and the controller are proposed for a decentralized architecture. The output of each sensor and actuator are asynchronously sampled by event-triggers that depend only on local information. The proposed controllers are shown to guarantee global asymptotic stability of the closed loop system, and provide global lower-bounds on inter-communication times. The proposed design methodology is illustrated through simulation results.
