摘要
为了提高小型光电编码器误差检测的精度和效率,拓展编码器误差检测的应用,设计了一种误差检测系统.通过对编码器误差来源分析,以步进电机为动力,DSP 芯片为数据采集与电机驱动核心,21 位高精度编码器为角度基准,搭建了可进行编码器动态误差与静态误差自动检测的系统.并通过对误差的分析与拟合,实现了对编码器的误差补偿,提高了被检编码器测量精度.经实际检测验证,所设计编码器误差检测系统达到设计要求.
Abstract
In order to improve the accuracy and efficiency of compact photoelectric encoder error detection and expand the application of encoder error detection,a error detection system was designed.By analyzing the source of the encoder error,a sys-tem that can automatically detect the encoder dynamic error and static error was built with a stepping motor as the power,a DSP chip as the core of data acquisition and motor drive,and a 21-bit high-precision encoder as the angle reference.And through the analysis and fitting of the error,it realized the error compensation of the encoder and improved the measurement accuracy of the inspected encoder.After actual testing and verification,the designed encoder error detection system meets the design require-ments.
