%X 工程实用的高精度感应同步器测角系统因安装及校准等条件的限制, 有时难以应用圆光栅进行误差密集测补来提高精度。针对该问题研究了一种稀疏误差采样及补偿方法。在分析感应同步器测角系统误差特性的基础上, 提出先测补零位误差引起的细分误差成分, 再处理剩余细分误差的方式, 给出了由棱体获取全面、有效零位误差的方法及应用稀疏误差数据补偿的具体过程。实验表明: 应用该方法后某测角系统精度由最大误差峰峰值11.7″提升至 2.9″。该方法零位误差剔除充分, 实现了稀疏采样条件下感应同步器测角系统误差的全范围有效补偿。<br>Abstract：Installation and calibration difficulties restrict the use of circular gratings to improve the precision of practical high-precise inductosyn-based angular measurement systems through angle-error sampling and compensation. The study analyzes appropriate solutions of sparse error sampling and compensation methods for this problem. The error characteristics of inductosyn-based angular measurement systems are analyzed to compensate for the subdivision error caused by the existing zero-point error and other subdivision errors to get the overall zero-point error with a prism. An error compensation method is then given using sparse sampling data. Tests show that the precision of an angular measurement system is improved by this method from a peak to peak error of 11.7″ to 2.9″. The method accurately identifies the zero-point error and provides full-range error compensation with sparse sampling data for an inductosyn-based angular measurement system.
