Event-triggered dynamic output feedback control for switched linear neutral systems under time-varying delays and frequent asynchronism

The study focuses on the event-triggered dynamic output feedback control for a type of switched linear neutral systems under time-varying delays and frequent asynchronism. Distinct from the existing literatures about asynchronous switching, which restricts the minimum dwell time, frequent switching is allowed to occur within each inter-event interval by reason of average dwell time method. Then, concentrated on switched neutral time-delay system, a novel sufficient condition is established under which proposed event-triggered control scheme guarantees its the global uniform exponential stability by using the controller-mode-dependent Lyapunov functional together with dynamic output feedback controller. Subsequently, the sufficient criteria are deduced for co-designing the dynamic output feedback controller and mode-dependent event-triggered mechanism. Additionally, it is proved that a positive minimum threshold on the inter-event intervals exists, which eliminates Zeno phenomenon. In the end, a numerical simulation indicates the efficacy of the acquired results.
