Abstract

This paper focuses on the problem of reliable H_infinite control for a class of switched nonlinear systems with actuator failures among a prespecified subset of actuators. In previous works, the reliable H_infinite design methods are all based on a basic assumption that the never failed actuators must stabilize the given system. But when actuators suffer "serious failure"--- the never failed actuators can not stabilize the given system, the previous design methods of reliable H_infinite control do not work. Based on the switching technique, the problem can be solved by means of switching among subsystems or finite candidate controllers.
