光纤陀螺温度漂移多变量模型研究

Research of Temperature Drift Multi Variables Model of IFOG

—温度漂移大是光纤陀螺进入工程应用所面临的最大难题之一。本文采用软件手段，通过对光纤陀螺温度漂移测试数据的分析，建立了光纤陀螺温度漂移的多变量自回归数学模型。此数学模型于实际情况具有很好的吻合性，不仅具有理论意义且具有实用价值，为解决光纤陀螺的温度漂移奠定了基础。

Large temperature drift is one of the most difficult problems in theengineering application of the interferometic fiber optic gyro(IFOG).In this papei,testing data of temperature drift of IFOG are analysed and a multi variables auto regression mathematical mod el is established,This mathematical model is very close to the actual status,so it is not only meaningful in theory but also valuable in application.With the help of this model,it is possible to compensate temperature drift of IFOG.
