【Abstract】 The reliable tracking controller design problem against actuator faults is studied. For linear uncertain systems, a more practical and general model of actuator failures is presented. Based on that, a sufficient condition about reliable tracking control is given. By means of LMI method, state feedback reliable controller is designed. A simulation example is given to illustrate the efficiency of reliable tracking control. Furthermore, the comparisons of the reliable tracking control with the normal tracking control show the necessity of reliable tracking control.更多还原
