A cooperative fault-tolerant control method for the coupled system based on interaction effect utilization
Résumé
An active fault-tolerant control scheme is proposed in this paper for the strongly coupled MIMO systems which subjected to total actuator failures. A control-oriented interaction indicator is defined in the Lyapunov stability sense and then is utilized to design the cooperative fault tolerant control law. The proposed scheme can achieve robust tracking performance with globally uniformly ultimate boundlessness and is capable of improving the transient performance (fault tolerant ability) by wisely using the interactions. Simulation results obtained on the flight attitude control system illustrates the benefit of the proposed techniques.
