Asynchronous Switching Control for Switched Delay Systems Induced by Sampling Mechanism

Event-triggered control is a control strategy, which possesses advantages in applications where communication resources are scarce. In this paper, we study event-triggered control for switched delay systems. The proposed triggering condition is satisfied only if an error signal exceeds a dynamic threshold. Sampler updates and transfers the information of states and switching signal to controller when the event is triggered, under which asynchronous switching cannot be avoided. We therefore consider asynchronous switching control for switched delay systems also. The switching signal is assumed satisfying an average dwell time condition, under which globally exponential stability of the closed-loop system can be guaranteed. Finally, a simulation example is given to show the developed result.
