Based on switched method linear systems reliable control

For linear systems, the switch method to design reliable controller is presented against actuator faults. By using strictly redundant reliable controller, standard controller is switched to reliable controller in the event of actuator faults. A more practical model of actuator faults than outage is considered. The resulting closed-loop systems are reliable in the sense that they provide guaranteed stability not only when all actuators are operational, but also when some actuator faults occur. Based on LMI, a sufficient condition for the existence of reliable control is given. Simulation results show the effectiveness of the design method. Furthermore, the standard system and the reliable system are compared to show the necessity of reliable control.
