Abstract:

This paper put forwards a new self-centering control algorithm by analyzing the principles of worktable adjustment based on that the section of angled cylinder is ellipse and put forwards two centering adjustment methods based on the differences of adjusting movements. Then the characteristic parameters of the elliptic by analyzing the spectrum were extracted. The algorithm software was finished by Labview. The simulation results show that the algorithm has features as short time, high precision and more efficiency. 

摘要：

依据倾斜圆柱横截面为椭圆,在分析圆柱度仪工作台偏心和倾角调整原理的基础上,提出了一种新的单截面椭圆测量自动对中控制算法;根据调整运动的不同,提出了两种对中调节方法;结合谱分析技术实现了椭圆特征参数的便捷提取;采用LabView编制了相应的算法软件。仿真结果表明,单截面自动对中调节方法耗时短、精度高,显著提高了圆柱度仪对中的效率。
