Abstract

The paper discusses the problem of temperature drift compensation in a fiber-optic gyroscope, using a number of temperature sensors distributed along the gyroscope coil. An algorithm is proposed for processing the sensors’ data in the form of weighted sum of temperature values and its derivative. The results of the proposed algorithm comparison with an algorithm that uses averaged readings of sensors are presented. It is shown that the proposed algorithm increases the compensation accuracy up to 50%.

一种利用陀螺仪读数与多个温度传感器之间的相关性进行光纤陀螺仪温度漂移补偿的方法

摘要

本文讨论了光纤陀螺仪中的温度漂移补偿问题，使用了沿陀螺仪线圈分布的多个温度传感器。提出了一种以温度值及其导数加权和的形式处理传感器数据的算法。给出了所提出的算法与使用传感器平均读数的算法进行比较的结果。结果表明，该算法将补偿精度提高了 50%。
