| 摘 要： | 谐振式光纤陀螺(Resonator Fiber Optic Gyro,R-FOG)是基于Sagnac效应产生的谐振频率差来测量旋转角速率的一种新型光学传感器.对基于调相谱检测技术R-FOG系统中的环路频率锁定技术进行了研究.通过对系统光学回路和处理电路部分分别进行建模,利用反馈控制系统理论,分析了整个环路的传递函数,得到了整个环路起主导作用的简化模型.利用该简化模型,在一定的光学回路参数条件下,得到了处理电路的最佳锁定参数,并进一步在实验中得到验证.

| Abstract: | Resonator fiber optic gyro(R-FOG)is a novel optical rotation sensor whose resonant frequency is changed due to the Sagnac effect.Loop frequency locking technique in phase modulation spectroscope technique R-FOG system has been researched.The simulation model for the optical loop and the electric circuits are setup separately.The transfer function of the whole closed loop system is analyzed using the feedback control theory.Then,the simplified model,which is playing the key role of the whole closed loop system,is obtained.Based on this simplified model,the optimized circuit parameters are achieved to lock the system quickly and stably.Furthermore,the analysis is verified by experiments. |
