The problem of reliable guaranteed cost robust control for a class of uncertain switched linear systems containing actuator failures is addressed in this paper. In earlier papers, the reliable controller design methods are all based on a basic assumption that the never failed actuators must stabilize a given system. But when actuators suffer "serious failure" - the never failed actuators cannot stabilize the system, the previous design methods of reliable guaranteed cost control do not work. Based on the switching technique, the problem can be solved by means of switching among subsystems. A sufficient condition for the existence of the state feedback reliable guaranteed cost controller is obtained by using multiple-Lyapunov function method. Furthermore, a convex optimization approach with LMIs constraints is introduced to select the optimal guaranteed cost controller. Finally, a simulation example illustrates the effectiveness of the approach proposed.
