Stabilization of Nonlinear Systems Using Event Triggered Output Feedback Controllers
The objective is to design output feedback event triggered controllers to stabilize a class of nonlinear systems. One of the main difficulties of the problem is to ensure the existence of a minimum amount of time between two consecutive transmissions, which is essential in practice. We solve this issue by combining techniques from event triggered and time triggered control. The idea is to turn on the event triggering mechanism only after a fixed amount of time has elapsed since the last transmission. This time is computed based on results on the stabilization of time driven sampled data systems. The overall strategy ensures an asymptotic stability property for the closed loop system. The results are proved to be applicable to linear time invariant (LTI) systems as a particular case.
