Reliable Control for a Class of Switched Nonlinear Cascade Systems

This paper focuses on a class of switched nonlinear cascade systems with controller parameter perturbations, while considering the case of partial actuator failures. First, assuming that the nonlinear term satisfies the norm-bounded condition, a reliable fault-tolerant controller is proposed using the average dwell time method. Then, the sufficient conditions for the global exponential stability of switched systems are given against allowable uncertainties and actuator faults under any switched signals. Finally, the effectiveness of the proposed method is verified through numerical simulation.
