N2 - In this paper, the problems of fault estimation and fault tolerant control for motor servo systems are investigated. The motor servo systems are modeled as continuous-time linear systems with unknown inputs and actuator faults. Based on the faulty system model, a robust fault estimation and active fault tolerant control scheme is proposed. In this scheme, an observer-based robust fault estimator is designed to obtain the magnitude and characteristics of the faults; then, on the basis of the estimated fault information, an output feedback active fault tolerant controller is constructed to keep the post-fault dynamic system robust asymptotically stable. Simulation results illustrate the applicability and effectiveness of the proposed approach.
