摘要: 高准确度的角度/直线编码器广泛应用于角度或位移测试计量。在惯导测试设备的伺服控制中,为提高角位置准确度和重复性、改善角速率准确度和稳定性,高准确度的编码器和具有高倍频细分功能的数据采集卡普遍用于角度定位和速率伺服控制。以一款多功能倍频细分计数卡(IK220)为例,研究实时操作系统下的数据采集方法,该方法在精密伺服控制中使用良好、作用显著。
关键词: 光栅, 编码器, 配置寄存器
Abstract: The high accuracy angle and liner encoder are used widely in metolgy and measurement.In the field of servo control for INS Mesuremend Device ,to improve the positioning accuracy and repeatability , rate accuracy and stability , The data acquisition circuit with the high multiple interpolation are applied for positioning and rate control.The data acquisition method in the Real Time System is Reaserched with a multifunctional interpolation counter circuit (IK220).The method acts markedly and effectively on the precision servo control in practice.
Key words: Optical grating, Encoder, Configure register
