74 New H∞ Controllers Design for Networked Control System with Disturbance Based on Asynchronous Dynamical System

In this paper, a class of networked control system (NCS) with disturbance, time delay and packet dropout is converted into a discrete-time system which could be viewed as an asynchronous dynamical system with rate constraints. For the system, based on Lyapunov stability theory and LMI approach we present two new state feedback controllers which can make the closed-loop system exponentially stable and meet prescribed or optimal H∞ performance index. A numerical example is worked out in detail to illustrate our results.
