Event-triggered control for neutrally stable linear systems subject to output saturation

In this paper, we design an observer-based event-triggered output feedback control law for neutrally stable linear systems with output saturation. The aim is to save the transmission resources of networked control systems. Under the proposed event-triggered strategy, the closed-loop system is globally asymptotically stable at the origin. Moreover, the minimum inter-event time has a strictly positive lower bound which indicates that Zeno behavior can be ruled out. Finally, the effectiveness of the adopted approach is illuminated by a numerical example.
