摘　　要：针对激光陀螺稳频装置易受温度变化的干扰的问题,为保证全温度范围内激光陀螺的稳频效果,提出了一种选模控制策略:根据陀螺扫模过程中得到的不同模态,通过比较各个模态下背向散射特征电压的大小,在常温下筛选出合适的陀螺及其控制模态,再经过温循实验进一步筛选出合适的模态,并固定用于全温度下的稳频控制以保证陀螺全温精度。最后通过实验验证,使用该筛选策略下获得的最佳模态,实现激光陀螺全温下稳定工作,满足实际工作要求。Aiming at the problem that the laser gyro frequency stabilization device is easily disturbed by temperature changing,in order to ensure the laser frequency stabilization effect of gyro over full temperature range,this paper designed a control mode selection strategy.According to different modal characteristics in the gyro sweeping mode process,by comparing the magnitude of the backscattering characteristic voltage in each mode,suitable gyro and its control modes were screened out at room temperature,and then through the temperature cycle experiment,the suitable modes were further selected and fixed for the frequency stabilization control at the full temperature to ensure the full temperature precision of the gyro.Finally,the experimental results show that the optimal mode obtained under the screening strategy is used to realize the stable operation of the laser gyro at full temperature,which meets the practical requirements.
