Abstract :
The stepping motor servo system is a nonlinear strong coupling system. It is difficult to control the complicated system by using traditional control theory. In this paper, the authors use fuzzy control combined with PI control theory to make the stepping motor servo system a fuzzy control system. They also designed an outer fuzzy control strategy to automatically compensate the position feedback pulse disturbance. Experimental results show that the new servo system has good performance
