基于磁旋转编码器的角度传感器动态误差补偿方法

摘要

An angle sensor based on magnetic rotary encoder was designed , and the reason for the sensor's dynamic error was analyzed , and then the method which can reduce dynamic error was presented .This method can compensate dynamic error effec-tively, also make the sensor's error less than 0.1°when used in dynamic measurement with high speed and high speed rate chan-ging.%设计了一种基于磁旋转编码器的角度传感器，分析了该角度传感器产生动态误差的原因，提出了可减小动态误差方法。该方法能有效地补偿动态误差，使角度传感器在转速高、转速变化快的动态测量中测量误差小于0.1°。
