Abstract

In this paper, an active fault-tolerant scheme with performance degradation is proposed in the presence of actuator saturation and fault. Firstly, the loss of control effectiveness fault is transformed into an virtual additive fault and then the effectiveness factors are estimated by a two-stage Kalman filter algorithm with a set of forgetting factors. In order to satisfy the output tracking performance, the fault-tolerant controller is consisted with a feedback control law and a feedforward control term in this paper. The feedback control is designed to maintain the stability of the closed-loop system. Considering the physical actuator limits, an performance degradation matrix is introduced to the feedforward control design. Besides, the feedforward control term and degradation matrix is solved by a constrained optimization problem. Finally, numerical simulation results are given to illustrate the effectiveness of the proposed method.
