Operator-based fault tolerant control for uncertain nonlinear systems using robust right coprime factorization

In this paper, operator-based fault tolerant control of the nonlinear feedback system with perturbations is studied by using robust right coprime factorization. In details, a new robust fault tolerant control strategy is proposed, wherein the fault tolerant controller combined with a tracking compensator is designed, such that the stability of the system is guaranteed, the influence of external disturbance on output is eliminated and the perfect output tracking of nonlinear feedback system is achieved simultaneously.
