A Control Proposal for Circle Contour Manufacturing in Rotary Coordinate System

Trajectory error always exist in circle contour manufacturing due to the servo system lag of industrial manufacture devices such as x-y ball screw which is used for two-dimensional manufacture, especially in high speed production. Sometimes, high frequency input commands also make the precision of circle contour manufacture even worse because of the weakness of usual controllers that position trailing deterioration of high frequency input. In other words, a common problem in most of control methods for circle contour manufacturing is higher frequency with longer servo lag and bigger trajectory error. In this paper, a control proposal for contour manufacturing which could cope with the high frequency input problem has been presented. At the end of this paper, the comparison of traditional method and proposal will show the effectiveness of the proposal.
