Event-triggered and self-triggered control for networked control systems with short network-induced delays: A switched system approach

Abstract

This paper investigates the event-triggered and self-triggered state feedback control problem of networked control systems(NCSs) with short network-induced delays. The proposed switched system modeling method is able to describe the uncertainty and the time-varying characteristics of the network-induced delays well. In this paper, for NCSs with short network-induced delays, we co-design the event-triggered condition, the discrete-time state feedback controller and the corresponding switching rule to maintain the stabilization of such a NCS. The presented event-triggered condition only needs to compare the state information of the adjacent sampling instants instead of the inter-sampling states, which can avoid the Zeno behavior that may cause event to be triggered infinitely within finite time. In addition, we design a self-triggered control strategy for NCSs which is allowed to choose when the next sampling time occurs based on the current sampled states and a priori knowledge about the plant.
