Abstract: The T-S fuzzy system with disturbance and fault is considered in the paper, and an observer with disturbance attenuation and fault detection is designed. With the linear matrix inequalities method, a sufficient condition on the existence of the observer with disturbance attenuation is provided, and a sufficient condition on the existence of the observer with fault detection is given, the two performance indices are then combined, and an optimization problem is formulated to solve the two problems simultaneously. A numerical example is given to show the effectiveness of the proposed method.
