Analysis on Temperature Modeling and Compensation Mothed of FOG

摘要:

通过光纤陀螺温度试验,分析了光纤陀螺的温度特性；理论上阐述了各项温度因素对光纤陀螺零偏的影响,并采用逐步回归分析的方法建立光纤陀螺零偏的温度数学模型。通过试验验证,采用该模型对光纤陀螺进行温度漂移的补偿,可以有效提高光纤陀螺的测量精度。

Abstract:

Based on temperature experiment, the temperature characteristic of FOG’s modeling was studied, the factors ef. fected on gyro’s modeling was analyzed. From the aspect of theory the effect on the FOG’s modeling was studied, andsome useful methods was proposed in this paper to found the temperature compensating model. The model was used tocompensate the FOG’s modeling for reduce gyro’s error. The results of compensation showed that the stability was en. hanced and the compensation model was effective.
