摘要

针对在不同的温度下光纤陀螺漂移差异很大的问题,文中从理论和大量实验上研究了光纤陀螺的温漂特性,分别建立了逐次启动零位和一次启动零位补偿的数学模型,并给出了工程上的建模方法和步骤。试验结果表明:补偿后无论是不同温度下的陀螺漂移差值还是一次启动漂移的稳定性都有显著改善和提高。

Abstract

Aimed at the problem that the drift of fiber-optic gyro varies wildly at different environment temperature, the characteris-tics of drift of the fiber-optic gyro were studied through abundant experiments. The error model was established to compensate the drift and also the modeling approach was given in details. The results show that drift difference of gyros and the stability of drift are obviously enhanced and improved after compensation.

Key words： fiber optic gyro; gyro drift; temperature compensation
