Event-Triggered Dynamic Output Feedback Control for LTI Systems

Abstract

This paper is concerned with the event-triggered dynamic output feedback control for linear time invariant (LTI) systems subject to actuator saturation. Firstly, a novel event-triggered scheme and dynamic output feedback controller are presented. Under the proposed framework: (a) the samplings of the sensor are designed as specific time-varying signals utilizing exponentially decaying function; (b) the dynamic feedback controller is equipped with an anti-windup compensator; (c) a lower bound of the inter-event interval is derived to exclude the Zeno behavior. Secondly, by constructing Lyapunov function and generally sector condition, some sufficient stability criteria are derived via linear matrix inequalities. Thirdly, depend on the stability criteria and MATLAB LMI toolbox, the parameters of event-triggered scheme and the controller are calculated. Finally, the effectiveness of the proposed method is illustrated by a numerical example.
