Abstract
Controller failures degrade a control system performance. In this paper, a novel maintenance approach for controller failures is proposed to restore the degraded performance of the controller. The method is to equivalently shift any fault occurring in a controller to the plant. Based on the assumed process model, a compensator with a serial link is designed to maintain the faulty controller in the SISO and MIMO control systems. Several simulation results are given to illustrate the procedure of using the method.
