摘要

针对测角系统在线校准问题,提出了一种基于多读数头布局的自校准方法。通过多组传感器的测量数据,利用圆封闭原则和傅里叶级数的性质,建立测量值与误差之间的函数关系,并基于多读数头布局原理,对自校准读数头布局进行优化,以提高校准方法对误差的抑制能力,实现单读数头测角传感器的自校准。设计了单轴转台,搭建了自校准测角系统,并进行了实验验证。实验结果表明:测角系统采用自校准方法后,单读数头测角传感器的测角误差为6.10″,在相同的测量环境下,其校准精度接近借助外部参考标准的传统谐波标定方法。自校准方法可有效抑制测角误差,显著提高测量精度。

Abstract

In order to solve the problem of online calibration of angle measuring system, we propose a self-calibration method based on multi-head layout. Through the measurement data of multiple sets of sensors, the relationship between the measured value and the error is established with the properties of circle closure and Fourier series. Based on the principle of multi-reading head, the self-calibration reading head layout is optimized to suppress the error and achieve a single reading head self-calibration sensor. To carry out a test verification, we design a one axis turntable. The experimental results show that the angular error of the sensor is 6.10″ with the proposed self-calibration method. In the same measurement environment, the calibration accuracy is close to the traditional harmonic calibration method with external reference. It is proved that self-calibration method can effectively suppress the angle error and improve the measurement accuracy.
