nonlinear system with multiple bounded state delay using the Takagi-Sugeno (TS) fuzzy
model. First, a fuzzy-fault estimation observer (FFEO) design is proposed to achieve fault
estimation of TS models with actuator faults. Based on the information of online fault
estimation, a state feedback-fault tolerant controller (SFFTC) using the estimate of state is
designed to compensate the effect of faults by stabilizing the closed-loop system. The …
