Abstract :
The fault-tolerant controller for a class of nonlinear networked control systems with time-varied delays is proposed. Aiming at the networked control systems composed by a class of nonlinear plant and the state feedback controller, the sufficient conditions for systems maintaining exponentially stability against actuator or sensor failures are given respectively based on Taylor linearization theory and Lyapunov stability analysis method. The fault-tolerant controller is designed using linear quadratic optimal control theory. Simulation results show the feasibility and effectiveness of the proposed method.
