Robust fault-tolerant control for a class of nonlinear time-delay systems

In this paper, the state-feedback robust stabilization of nonlinear time-lagged continuous systems is investigated by modeling the nonlinear time-lagged systems, applying Lyapunov stability theory and LMI toolbox, and designing the fault-tolerant controllers for nonlinear continuous systems by using the memoryless state-feedback controllers. Sufficient conditions for the system to be asymptotically stabilized in the case of actuator failure and the corresponding design method of the state feedback robust fault-tolerant controller are given. Finally, the reliability and effectiveness of the method are verified by numerical examples and simulation results.
