直线电机XY平台交叉耦合迭代学习控制
Cross-coupled iterative learning control for XY table of linear motor
摘要
Abstract
In order to avoid the periodic contour errors generated in the periodic contour machining process for the XY table of linear motor, a cross-coupled iterative learning controller combining iterative learning control with cross-coupled control was designed. The contour errors were estimated with real-time contour error estimation model, and the periodic contour errors were weakened by iterative learning controller. According to the cross-coupled gain relationship, the compensation amount of X and Y axes was assigned, respectively. In addition, the real-time compensation of periodic contour errors was realized. The theoretically derivated and simulated results show that the proposed scheme can not only effectively decrease the contour errors for the XY table of linear motor, but also enhance the robustness of the system.关键词
