Abstract

Reliable control of pole placement was presented for linear systems with continuous gain actuator faults. When faults occur, the closed-loop poles of standard system are out of a specified sector region. However, the closed-loop poles of reliable system are still in a specified sector region not only when all actuators are operational, but also when some actuator faults occur. Based on LMIs, a sufficient condition for the existence of reliable control is given. The helicopter CH-47 simulation results show the effectiveness of the design method. Furthermore, the standard system and the reliable system were compared to show the necessity of reliable control.
