High Precision Inductosyn Angle Measuring System Based on Resolver-to-angle Converter

设计了一种基于轴角转换器AD2S80的高精度感应同步器动态测角系统,分析了测角误差产生原因,提出了误差调整和补偿措施。通过实测数据表明:用谐波分析的方法对测角误差进行了调整与补偿,从而可大幅度提高测角精度。

This paper designs a high precision inductosyn angle dynamic measuring system based on resolver-to-angle converter. The reason of causing angle-measuring error is analyzed and the method of error adjusting and compensating is put forward. With the way of harmonic analysis, the angle measuring error is adjusted and compensated through true measuring data. Angle measuring accuracy is improved greatly with this method.
