Abstract
The servo-driven system built a bridge between the numerical control device and machine tools and the robustness, rapidity and accuracy of CNC system are highly determinate by it. In this paper, a representative servo control module of CNC system will be addressed. Based on that, the mathematical models of close-loop controls with current-loop (integral element), position-loop (proportional element), speed-loop (derivative element) and feedforward control are established. The effect of static and dynamic performances are analyzed with the tuning parameters of each close-loop controller and the experimental verification are performed using the tool of SERVO GUIDE software.
