环形激光陀螺仪（ＲＬＧ）的控制电路和信号处理方法直接影响着ＲＬＧ的使用精度及净信号输出频率等性能。为研究通过改进控制电路和采用信号处理来提高ＲＬＧ精度和改善其动态性能，满足惯性测量组合（ＩＭＵ）使用要求，本文研究了一种新的Ｌ－１型ＲＬＧ控制电路，并在此基础上，实现了高频采样；本文还介绍了一种高频采样中去除抖动的方法，以及相关信号处理技术。实验结果表明，本文电路和信号处理技术，改善了ＲＬＧ的信号使用精度，提高了其角速度信号输出频率，改善了Ｌ－１型ＲＬＧ的动特性。
Ring laser gyro (RLG) control circuit and signal processing methods directly affect the accuracy of RLG and net signal output frequency performance. In order to improve the RLG accuracy and improve the dynamic performance of the RLG by improving the control circuit and using signal processing and meeting the IMU requirements, a new type of L-1 RLG control circuit is studied. Based on this, , To achieve high-frequency sampling; This paper also introduced a method of removing jitter in high-frequency sampling, and related signal processing techniques. The experimental results show that the circuit and signal processing techniques in this paper improve the RLG signal usability, improve the angular velocity signal output frequency and improve the dynamic characteristics of L-1 RLG.
