| Abstract | 为解决旋转编码器在大口径高精度射电望远镜使用中，对安装工艺要求极高，需要专用设备校准，且安装后需要通过一段时间的运行，建立误差修正模型进一步提升编码器精度的问题，开展了编码器快速校准方法研究。提出了一种基于粒子群算法(PSO)的旋转编码器快速校准方法。根据伺服电机恒转速运行时，角位移变化率为常量的原理，通过编码器采样数据与伺服电机恒转速参考值对比后获得编码器安装误差。利用PSO算法快速拟合误差，从而校准编码器。通过构建编码器校准方法验证平台实测，此方法可将有较高安装误差的高分辨率旋转编码器实际测量准确度恢复3～4位，为大口径射电望远镜编码器定期精度监测与修正提供一种简易方法。 |
| Other Abstract | In order to solve the problem that rotary encoder has high installation technology requirement in the use of large aperture and high precision radio telescope,professional calibration equipment is required, and the encoder accuracy needs to be further improved by establishing error correction model after a period of work. The fast calibration method of encoder is studied in this paper. A fast calibration method of rotary encoder based on Particle Swarm Optimization( PSO) is proposed. According to the principle that the angular displacement change rate is constant when the servo motor is running at a constant speed,the encoder installation error is obtained after the encoder sampling data is compared with the servo motor's constant speed reference value. Use the PSO algorithm to quickly fit the error and calibrate the encoder. A test platform is established,which is used to verify the encoder calibration method. According to the test results it is found that the encoder calibration method could restore the actual measurement accuracy of a high-resolution encoder with a high installation error to 3 to 4 digits. It provides a simple method to monitor and correct the encoder of large aperture radio telescope periodically. |
