摘要

针对棱镜式激光陀螺稳频精度较低的现象,系统地研究了棱镜式激光陀螺稳频控制系统特性。理论分析了光强调谐曲线及稳频执行机构的特征,建立了棱镜式激光陀螺稳频控制系统数学模型。进一步分析了系统稳态性能及动态性能,分析结果表明,系统在定温及慢变温作用下具有不同程度的稳态误差且调节时间过长,从而导致稳频精度下降。优化控制器参数使二阶系统具有最佳阻尼比及快速性,采用按温度补偿的前馈控制系统,实现了对温度所引起的稳频误差的全补偿,提高了系统的稳频精度。实验结果表明,优化后的稳频控制系统比原稳频控制系统的稳频精度提高一个数量级,陀螺精度提高30%以上。

Abstract

In view of the low frequency stabilization accuracy of prism laser gyros, the characteristics of frequency stabilization control system of prism laser gyros are systematically studied. The light intensity tuning curve and the frequency stabilizing actuator are analyzed theoretically. The mathematical model of the frequency stabilization control system of the prism laser gyros is established. The steady state performance and dynamic performance of the system are further analyzed. The analysis results show that the system has different steady-state errors and the adjustment time is too long under the influence of constant temperature and slow temperature change, which leads to the decline of the stability frequency accuracy. We optimize the controller parameters to provide optimal damping ratio and rapidity for second-order system. And the feedforward control system with temperature compensation is adopted to realize the full compensation of the frequency stability error caused by the temperature and improve the frequency stability accuracy of the system. The experimental results show that the optimized frequency stabilization control system can improve the frequency stability accuracy by one order of magnitude compared with the original frequency stabilization control system, and the gyro accuracy can be improved by more than 30%.
