Research on the Positioning Servo Control Strategy for CNC System

Abstract:

In order to overcome thelimitation of the position servo control method of computerized numerical control(CNC) system, a control approach of generalized predictive control (GPC) ispresented in this paper. In the method, the GPC model calculates the optimalcontrol rate through the predictive model and rolling optimization as thecontroller of the position servo system. Compared with GPC and proportional-integral-derivative(PID) control, the simulative and experimental results show that the proposedcontrol approach has better the dynamic performance, steady-state performance,and robustness.
