| 摘 要： | 研究了模拟选通积分电路的温度特性对陀螺性能的影响。在数字闭环光纤陀螺工作原理的基础上，推导出陀螺输出与模拟选通积分电路中积分电容值的线性关系，进行了电路的温度性能试验，试验结果证实了理论推导，据此建立了线性模型并进行了补偿，补偿后陀螺零偏稳定性提高了75%。

| Abstract: | The influence of analog selection integral circuit on the FOG over temperature range is researched in this paper.A linear relationship between the output of FOG and the integral capacitance is deduced theoretically,which is verified in the temperature experiments while separating photo-electricity.A linear model between the output of FOG and the circuit temperature is established to compensate the output of FOG,and the bias stability of the FOG is improved by 75%. |
