In view of the influence of partial failure of actuator and system modeling error on the operation of the wind power system, a global fast terminal adaptive active fault-tolerant control strategy (GFTAFTC) is proposed. A dynamic model of angular velocity tracking of wind power generation system based on generalized disturbance is constructed, and the amplitude of the generalized disturbance boundary is estimated online through the design of adaptive law, and the actuator failure of the system is dynamically compensated. The global fast terminal sliding mode control is introduced to speed up the transition process of fault compensation. The first-order integration operator is used to further reduce the chattering, so as to smooth the torque and improve the performance of the system. In addition, the Lyapunov method is used to prove the global stability of the maximum wind energy tracking control system for wind power generation based on GFTAFTC. Finally, the simulation results are compared with the other four methods, verify that the GFTAFTC strategy can maintain good MPPT tracking performance in the failure state of the system actuator, and exhibits a certain degree of robustness and adaptability.
