| 摘 要： | 在不同调制深度下，光纤陀螺反馈通道的非线性误差对陀螺输出精度会有不同的影响。在此研究的基础上，通过实验与仿真分析相结合的方式，对光纤陀螺反馈通道非线性误差的温度特性也做了进一步的研究。研究表明，随着温度的降低，非线性误差对输出的影响也随之增加。仿真采用光纤陀螺单轴板在温箱中测得的数据，并利用Simulink建模分析。

| Abstract: | It is known that square wave modulation of different phase will affect output accuracy of fibre optic gyroscope. Above that, the research on temperature feature of fibre optic gyroscope has been done by analyzing experiment and simulation. Research shows that, the lower temperature is, the more severe affect output have. And the expression of nonlinear error was given. The simulation use data which from circuit board in incubator for simulation, and use simulink for further analyse. |
