Event-based H∞ finite-time reliable control for networked control systems

This paper investigates the event-triggered H

finite-time boundedness issue for networked control systems (NCSs) with actuator failure and network delay. First, a delay system model for NCSs is constructed under event-triggered scheme. Then, by using Lyapunov-Krasovskii functional method, some sufficient conditions are obtained such that the resulting closed-loop system is finite-time boundedness with a prescribed H

performance. Moreover, the co-design conditions for the event-triggered parameter and the reliable state feedback controller are given in the form of linear matrix inequality. Finally, a numerical example is provided to illustrate the efficiency of the proposed method.
