Cross-coupled iterative learning contour compensation for high speed motion based on modified reference input

摘要

This paper focuses on the control of the contour error of the two axes servo motion control system. In order to improve the accuracy of the system under high speed motion, a series of cross coupled iterative learning Contour error compensation algorithm is proposed, and the estimation model of contour error and the precondition of the application of the verification algorithm-platform repeatability are presented. Verification compensation algorithm is better than iterative learning or contour control. Experiments show that the algorithm can effectively reduce the contour error of the system and improve the control accuracy of the system.
