Abstract

The problems of robust H-infinity fault tolerant control with time-delays are studied for a class of nonlinear networked control systems. The T-S fuzzy model is employed to describe nonlinear plant. By established actuator fault model, the state feedback controller is designed. A sufficient condition for the asymptotic stability of closed-loop system is given based on Lyapunov stability theory and linear matrix inequality method, which can guarantee robust stability of network control system with actuator faults and disturbances.
