摘要
本文分析了以旋转变压器为角度传感元件,跟踪型轴角数字转换器为角度测量元件的测角系统的静态和动态误差,指出了导致测量误差的各种因素以及误差的具体表达式。分析表明角度传感元件的某些误差可以通过适当调整轴角数字转换器的参数予以补偿,从而提高整个测角系统的测量精度。
The static and dynamic errors of tracking Resolver—to—Digital (R/D)converter based angular position measurement system are analyzed in the paper.The effects ofnonideal resolver and R/D converter signal characteristics commonly encountered in practice areinvestigated.Expressions for the position error that results from the presence of each nonidealcharacteristic are derived.It is found from these expressions that some position errors resultedfrom nonideal resolver signal characteristics can be compensated by adjusting the R/D converterparameters properly so as to increase the accuracy of the position measurement system.
