摘要
光纤陀螺在实际应用中必须要考虑的一个问题是温度变化速率对其热漂移误差的影响。从理论上分析了温度变化对光纤陀螺热漂移误差的影响。进而设计了一个循环变温实验,得到了光纤陀螺在7 种不同变温速率下的热漂移误差大小。根据实验数据,通过选择合适的函数参数,拟合得到了变温速率与光纤陀螺热漂移误差的关系式,并使拟合得到的误差最小。通过该拟合函数,可以得到光纤陀螺在任意变温速率下的热漂移误差大小,并依据拟合的函数参数对光纤陀螺的热性能进行评价。
Abstract
In practical applications, the effect of the temperature changing rate on the thermal drift error of a fiber optic gyroscope (FOG) can not be ignored fiber optic gyroscope (FOG) due to temperature variation. Effect of temperature variation on thermal drift error of FOG in theory is analyzed. Then a temperature cycling experiment is designed to obtain the thermal drift error in seven temperature rates. Based on experimental data, a function is utilized to describe the relationship between temperature changing rate and thermal drift error of the FOG. With this fitting function, the thermal drift error of a FOG under any temperature changing rate will be obtained, and parameters of the function can be used to evaluate the thermal performance of a FOG.
