Robust <i>Η_∞ </i>Controller Design for Networked Control Systems with Exponential Convergence

Abstract

The output feedback exponential robust control for networked control systems with stochastic network-induced delay and packet dropout is studied. Firstly, a state observer is designed for estimating the state values and compensating data dropouts. Then the closed system is modeled as asynchronous dynamical system constrained by configuration event rate. By using Lyapunov principle, sufficient and necessary conditions for robust stability and exponential stability of the closed loop system is obtained and the output feedback controller design method is presented. Simulation example for the design is done, comparing with the other relative methods, the results shows the validity of the method.
