旋转变压器_感应同步器双通道测角系统一次谐波误差补偿.pdf

1997 5 2 ( 哈尔滨工业大学) 由旋转变压器和感应同步器组成的精粗双通道测角系统可 到较高的精 度。但由于感应同步器安装、布线等原因会造成 一次谐波误差。要提高测角精度, 必 须对一次谐波误差进行补偿。本文对一次谐波误差进行了定量分析, 并提出了一种有 效的补偿方法。 One Secondary Harmonic Wave Error Compensation of Two Channels Test Angle System Consisting of Resolver and Inductosyn Zeng ingshuangZhang Xiuyun ( Harbin Instit ute of T echnology) ABSTRACTT wo channels test angle sy stem co nsisting of aresolv er and an inducto syn can g ain quit e high accur acy.
