As for the disadvantageous influence on the flight simulator servo system caused by external disturbance, system uncertainties and model parameters fluctuating, an adaptive nonsingular fast terminal sliding mode controller is designed, and the stability of the system is proved. The fuzzy disturbance observer is used to compensate the disturbance and uncertainties. Combining nonsingular fast terminal sliding mode control with fuzzy disturbance observer, the proposed controller also has the advantage of small tracking error and good dynamic performance. Experiment results on flight simulator are presented to demonstrate the effectiveness of the proposed algorithm. The results show that compared with fast terminal sliding mode control, the proposed control algorithm has better tracking accuracy with fast respond speed, and good low-speed and high frequency characteristics in a proper frequency range.
