高精度角度传感器自动标定系统

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。Auto　Demarcating　System　for　High　Accuracy　Angular　Sensor

Abstract：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　instrument　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．
