高精度步进电机角度位置跟踪系统设计

Designing of High Precision Angle Position Tracking System for Stepper Motor

文章介绍了一种基于高细分驱动模块 ,用于角度位置跟踪的步进电机闭环控制系统。脉冲控制部分采用了 40 0细分的微步运行方式使步距角仅为 0 .2 7′,提高了步进电机的控制精度 ;位置反馈部分测量元件选用多极双通道旋转变压器 ,采用粗精组合的 2

In this paper,close loop control system of stepper motor base on high micro step driver module is proposed for the angle position tracking. In the part of pulse controlling,the step size is 0.27′ through micro step running style of 400 dividing. In the part of position feedback,high precision angle tracking is carried out through the mutipole two speed resolver and the fusion of 21 bit coarse fine angle signal.
