中文摘要: |
旋变编码器受误差因素影响,会在转速位置测量时引入周期性波动,不利于运动控制。对此提出了基于电压矢
量和转速的误差校正方法,采用电压矢量计算直流偏置和幅值偏差并对其进行校正;采用转速谐波幅值计算相位偏差并
对其进行校正。实验结果表明转速位置波动得到了很好的抑制。该方法能有效校正旋变编码器误差。 |
英文摘要: |
Because of the error sources, a resolver may introduce periodic errors in speed and position measurement, and
it is harmful to adjust speed drive systems. The correction method to different errors was proposed based on the voltage
vector and speed. Computing DC offset and amplitude error was corrected by voltage vector. Computing phase imperfect
quadrature was corrected by speed harmonic. Experimental results indicate that the speed and position fluctuations are
well suppressed. The method can correct resolver error effectively. |
