Dynamic Output Feedback Control for Systems Subject to Actuator Saturation via Event-Triggered Scheme

In this paper, the event-triggered dynamic output feedback control problem for linear systems with actuator saturation is investigated. Event-triggered scheme only transmits the corresponding signal when the event-triggered condition is violated. Due to its advantage of saving communication resources, it is utilized to design the dynamic output feedback controller. A criterion is established to guarantee the stability of the closed-loop system by introducing an exponential term for the Lyapunov function, which corresponds to the exponential term in the event-triggered condition. The explicit design of the coefficient matrices of the controller is presented. Furthermore, a lower bound of the inter-event time is calculated to avoid Zeno behavior. An optimization algorithm is then formulated to maximize the estimation of the domain of attraction. Finally, a numerical example is given to illustrate the effectiveness of our methods and to show the trade-off between the size of the domain of attraction and communication resources saving.
