摘　　要：采用直流力矩电机分度,同步采集系统进行数据采集,对高精度两路关联角度传感器自动标定。为了实现秒级角度的自动标定,采用了闭环控制系统和角度误差补偿,在±3°范围内,控制精度可达到0.2″。利用虚拟仪器技术整合数据采集和控制系统,使得标定高效方便。An auto angle-differentiated controlling device and data synchronized acquisition system for demarcating of a high accuracy angular sensor system are developed. The controlling system is a DC servo system using a rotating grating measuring system monitor the angle position, which the precision of the controlling angle is 0.2″ within the measuring range of ± 3° after error correction. Two signals of the sensor system can be synchronized sampled through the data acquisition system. Using virtual instnm^ent technology, it can be done automatically that the measuring and data processing and the errors of manual operation will be avoided, so improved the efficiency.
