Application analysis of servo-control system based on PMAC with feed-forward control

On the basis of traditional PID algorithm, the paper analyzes the improvements of control algorithm of PMAC (Programmable Multiple-Axis Controller) with feedforward control, and presents the computational model of the control algorithm. The debugging results of motors are analyzed in combination with PMAC as the controller. The problems and the final graphics data that appear throughout debugging process are analyzed in detail, which proves that there are better steady characteristics and dynamic performance for the servo-control system based on PMAC with feedforward control. The control system is rebuilded by parameter-adaptive PID+feedforward control for higher machining accuracy.
