Reliable tracking control system design against actuator failures

A method is presented to synthesize a reliable controller for dynamic systems possessing actuator redundancies. The designed controller will be able to guarantee the dynamic stability and to maintain the steady-state tracking performance of the closed-loop system in the event of actuator failures. The method is based on robust pole region assignment techniques with the help of a pre-compensator to modify the dynamic characteristics of the redundant actuator control channels. The tracking capability is obtained by an outer PI control loop. The effectiveness of this method has been verified on an aircraft bank angle control system design. The results indicate that the proposed scheme is indeed very effective in achieving the closed-loop system integrity in the presence of actuator failures.
