摘要
Shupe效应导致光纤环圈对温度变化特别敏感,进而引起光纤陀螺产生较大的零偏漂移。对光纤陀螺输出信号进行温度补偿是一种抑制Shupe误差的有效手段,其中的关键技术是建立一个适合各种温度环境的精确补偿模型。本文基于Shupe误差机理,提出了一种精确补偿光纤陀螺温度误差的方法。通过设计两种温度环境测试实验,可以分别提取光纤陀螺在每个温度点上的温度及温度梯度系数,并对两组系数曲线分别进行多项式分段建模。通过调节温箱温度范围和变温速率,可以适合不同精度光纤陀螺零偏漂移的补偿。试验测试表明,该方法可以有效提升光纤陀螺的零偏稳定性,补偿后精度优于0.002?/h。
The fiber coil is very sensitive of the temperature change since the Shupe effect, and then it brings the zero drift of fiber-optic gyro. It is an effective method to suppress the Shupe effect using the temperature compensation technique. The key is how to establish an accurate compensation model suitable with all kinds of temperatures. According to the theory of Shupe error, an accurate temperature compensation method is proposed. The coefficient curves of temperature and temperature rate are obtained by two experiments of temperature. The two coefficient curves can be used to establish the model using fitting of a polynomial. This compensation model method is suitable for different precision of the fiber-optic gyro. The experimental result shows that the bias stability of a high fiber-optic gyro is better than 0.002?/h after compensation.
