Observer-Based Event-Triggered Control with Disturbance Compensation
This paper presents a new event-triggered control strategy for systems with unknown external disturbance.To reject the disturbance actively,the descriptor observer is implemented to estimate both the state and disturbance simultaneously,then the composite controllers are proposed.Furthermore,both the updating instants and the event-triggered controller are designed with the aid of state and disturbance estimates.It can be shown that the states of the closed-loop system with the proposed event-triggered controller is uniformly ultimately bounded and the Zeno behavior can be avoided owning to the minimum inter-event time is lower bounded.Finally,the simulation results demonstrate the effectiveness of the proposed method.
