Abstract :
An adaptive terminal sliding mode control method based on the fuzzy disturbance observer (FDO) is designed, in order to eliminate the influences of the total disturbances and be applied easily. The stabilities of this method are proved strictly based on Lyapunov´s direct method. Furthermore, by modifying the adaptive law of the FDO, a fast fuzzy disturbance observer is presented to improve the convergence speed of FDO. Then the FFDO is used in the design of the flight control system of near space vehicle (NSV).
