In the use of servo motor control system, some characteristics of motor, such as non-sinusoidal flux of motor mover caused by end effect, nonlinear friction, will make the effects of the servo system bad. So we must use some control strategies with high robustness to suppress these disturbance. In this paper, a design method of fuzzy sliding mode control system with adaptive integral sliding mode surface, and applied to the position control of servo motor system. Adaptive fuzzy sliding mode control system consists of fuzzy control and switching control, using fuzzy controller to simulate feedback linearization control rate, output error using the switching control to compensate the sliding mode controller. Control algorithm is derived from the Lyapunov stability theory, which can guarantee the stability of the system. Simulation results show that, the system performance is the satisfaction, and it’s robust with regard to the parameter variations and external load disturbance.
