摘要
In this paper, we mainly focused on designing a actuator fault detection filter for the discrete-time switched linear systems under output disturbance case. Firstly, an efficient condition is obtained to guarantee the residual system is admissible and satisfies a prescribed. H-infinity performance index. Then based on switched Lyapunov function and descriptor observer approach, the designed fault detection filter is successfully obtained. Finally, a numerical example is provided to illustrate the obtained results.
