Laser Gyro Simulation Research Based on the Optimization of Jitter Rrequency

为了克服激光陀螺的闭锁效应,分析了闭锁效应产生的机理,提出了优化的抖动偏频,设计了激光陀螺抖动系统。然后利用MATLAB软件对优化抖动偏频条件下的激光陀螺开展仿真研究。结果表明:抖动偏频激光陀螺存在着动态锁区,采用优化后的抖动偏频可以很好地克服动态锁区,提高了激光陀螺输入-输出曲线的线性度和陀螺准确度。

In order to overcome the blocking effect of laser gyro,analysis of the mechanism of the blocking effect and put forward the optimization of frequency jitter,laser gyro dither system is designed. Then use MATLAB software to optimize the jitter frequency under the condition of the laser gyro simulation study. The results show that the dithering exists partial frequency laser gyro dynamic lock area,using the optimized frequency jitter partial dynamic lock area is a good way to overcome and improve the laser gyro input-output curve linearity and accuracy of gyro.
