摘要：
To design an AC laser frequency stabilization system for the space three-axis mechanical dithering laser gyro, the principle of the AC frequency stabilization system is analyzed, the system simulation model based on Simulink tool is built, and the experimental research is made. In the principle analysis, the control procedure of the system is analyzed, the system function is deduced, and the influence of PID parameters on the system response in the AC laser frequency stabilization is explored through the system simulation model based on Simulink tool. Then, the optimal PID parameters (KP=0.048, KI =0.0021, KD =0.0037) are obtained, which can provide reference for the system debugging. Finally, the test experiment is made by applying the AC laser frequency stabilization system into some Chinese-made space three-axis mechanical dithering laser gyro. The experiment results show that the PZT code value and the gyro pulse output of the AC frequency stabilization gyro are stable by using PID parameters control, and the precision of the space three-axis mechanical dithering laser gyro is increased by 20% compared with that by the original DC laser frequency stabilization control method. © 2017, Editorial Department of Journal of Chinese Inertial Technology.
