Abstract : "In this paper, the problem of actuator fault detection for discrete-time switched systems with output
disturbance is investigated. By using the descriptor observer method, an H∞ fault detection filter is designed to
guarantee that the augmented system is admissible and satisfies a prescribed H∞ performance index. By utilizing
switched Lyapunov function approach, a sufficient condition for the admissible of the augmented system is obtained.
Based on the obtained results, a desired fault detection filter can be designed. All the results are formulated in the
form of linear matrix inequalities. Finally, an example is proposed to illustrate the effectiveness of the developed
Actuator fault, descriptor observer, fault detection filter, switched system.
