基于光纤陀螺温度漂移误差补偿方法研究

惯性导航系统中光纤陀螺的漂移受温度变化影响显著,导致其在导航系统中的应用受到各种制约。该文提出了一种软件上的温度补偿法,建立基于光纤陀螺多参量联合多项式温度补偿模型,并设计相应的试验方法对陀螺仪的漂移进行了温度补偿。试验证明,提出的温度模型准确有效,可补偿因温度变化引起的光纤陀螺仪的漂移影响,达到提高系统的导航精度及温度适应性的目的。

Study on Compensation Method of Temperature Drift Error Based on Fiber Optic Gyro

The drift of fiber optic gyroscope in inertial navigation system is significantly affected by temperature changes, which leads to various restrictions on its application in navigation systems. In this paper, a software temperature compensation method is proposed, and a multi parameter polynomial temperature compensation model based on the fiber optic gyro is established, and the corresponding test method for the temperature compensation of gyroscope drift is designed. The experiment show that the proposed temperature model is accurate and effective, which can compensate for the drift of optical fiber gyroscope caused by temperature changes, so as to improve the navigation accuracy and temperature adaptability of the system.
