摘要：

In this study, sensor fault estimation and accommodation for discrete-time switched linear systems are investigated. By using descriptor observer method and switched Lyapunov function technique, efficient conditions to design the fault observer are obtained via a linear matrix inequality formulation. Then, based on the estimation of the sensor fault, an efficient fault-tolerant operation can be realised via sensor fault compensation. Finally, an example is given to illustrate the developed technique.
