摘要：

The problems of fault diagnosis observer design and output feedback fault-tolerant control for a class of descriptor stochastic systems is studied. Firstly, a new augmented fault diagnosis observer is provided. By using Lyapunov second method, a sufficient condition of asymptotically admissible at level of H disturbance attenuation for the error dynamic system is given. Secondly, a dynamic output feedback fault-tolerant controller is designed based on the fault estimation. Finally, an example is given to illustrate the effectiveness of the proposed design.
