摘　　要：为实现伺服电机驱动回旋机构应用中的角秒级的角度测量精度。选用电气误差小于±10″的无刷双通道旋转变压器作为角度位置传感器,设计了双通道旋转变压器的激励及解算电路,通过数字信号处理器(Digital Signal Processor,DSP)TMS320F28335读取解算电路输出的角度位置。与传统的无刷双通道旋转变压器角度解算电路相比较,可以有效减少软件算法中数据整合和纠错部分的工作量。实验结果表明该系统能稳定输出高质量的角度位置指示信号。适用于伺服电机定位控制等需要高精度角度位置反馈的场合,具有可靠性高、精度高、软件开销少的优点。The aim of this study was to implement high precision angel measurement of rotary device. Two speed resolver which electrical error is less than ± 10″ was utilized to as angle position angle. Powering and decoding circuits were designed for the two speed resolver. The angle information was then read by Digital Signal Processor（DSP）TMS320F28335. Compared with other decoding methods of two speed resolver,this study can reduce software consumption on data integration and error correction. The results we obtained demonstrate this system could output high quality angle position indication signal with features of high precision,high reliability and simply coding.
