Event-triggered control for saturated switched system based on composite nonlinear feedback
For a class of switched systems with actuator saturation,the event-triggered control method with composite nonlinear feedback(CNF)controllers is proposed to ensure system performance while reducing network bandwidth consumption.Firstly,in order to reduce the cost of system resources,event-triggered conditions are constructed to determine whether to sample the current state of the system,and a composite nonlinear feedback control is designed to improve the transient performance of the system.Then,using the multi-Lyapunov function method sufficient conditions for the practical stability of switched saturated systems under switching signals satisfying dwell time are derived,and it is proved that the minimum time interval for event triggering is greater than zero,avoiding the Zeno behaviour.Finally,a simulation example is given to illustrate the effectiveness of the proposed method.
