英文摘要：

Considering the networked packet dropout of a singularly perturbed system under actuator failure, the original system was transformed to a singularly perturbed uncertain switched system. Then, the difficulty arising in the boundary dynamic behavior caused by a small parameter was overcome by using the matrix inequality technique. Meanwhile, the feedback stabilization of the singularly perturbed uncertain switched system was studied under some certain data dropout rate. Further, the design method of a controller and the sufficient condition of stabilization of the system were presented. Finally, a numerical example was given to illustrate the effectiveness of the proposed method.
