摘要
反馈信号的调制解调是数字闭环光纤陀螺中信号处理系统的核心部分,尤其是阶梯波的反馈特性对整个光纤陀螺系统的稳定性有很大的影响。从数字闭环光纤陀螺的原理出发,将光纤陀螺系统中的光信号、电信号结合起来,分析阶梯波反馈的原理及影响其反馈特性的各种因素。构建数字闭环系统的控制流程图,并推导出系统的传递函数,分析了高精度光纤陀螺的信号处理方案,对光纤陀螺干涉信号的测试说明了原理的可行性。
Feedback signals＇ modulation and demodulation is the core of digital-loop fiber optic gyroscope （FOG） ＇s signals processing system. Especially, the character of ladder-wave＇s feedback signals has great effect on the whole FOG system＇s stability. The contents in paper analyzed the principle of ladder-wave＇s feedback and the factors related to ladder-wavers stability by uniting electronic signals with optic signals. We constructed flow chart of control system, deduced transfer function, and introduced scheme of high-precision FOG. The test to FOG＇s interference signals proved the principle＇s feasibility.
