摘要：This paper addresses a fault-tolerant control scheme for a class of nonlinear systems based on the adaptive fault diagnosis method. Considering the nonlinearity of systems satisfies the Lipschitz condition, the adaptive law is designed according to the Lyapunov theory, and the proposed augmented adaptive observer can not only endure the nonlinearity but also broaden the application scopes of general adaptive observer. Then, a fault- tolerant controller is designed to compensate for the effect of the faults and guarantees the closed-loop system stable. Finally, a numeral example is presented to illustrate the effectiveness and feasibility of the addressed approach.
