Anti-Windup Compensation for Asymmetric Saturated System Based on Event- Triggered Dynamic Output Feedback Controller

The anti-windup compensator design utilizing event-triggered dynamic output feedback control for asymmetric saturated system is first investigated in this paper. Asymmetric saturation frequently appears in practical control systems, which will seriously reduce the performance of the system. As not all the states of the system are easy to be detected directly, a modified dynamic output feedback controller is employed. A saturation-related event-triggered condition is proposed. Moreover, the simultaneous utilization of anti-windup compensator and event-triggered mechanism would not only reduce the undesired effect of asymmetric saturation, but also save the calculation and communication resources. In addition, the minimum triggering time interval is calculated to avoid the Zeno behavior. Enlargement of the estimated stable region for the closed-loop system is mentioned by an optimization algorithm. The proposed results are then illustrated by a numerical example.
