| Abstract: | In view of the servo system of BVXK20A NC machines,using fuzzy PID control theory,a fuzzy controller of NC machines is designed.Based on.fuzzy control rules,PID parameters are modified timely for better adaptive ability.The dynamic simulation of the servo system of NC machines based on MATLAB is carried out.The simulation results show this controller has fast response performance and strong robustness when external interference occurs and work conditions change. |
