摘　　要：激光陀螺设计时均采用光强控制系统和程长控制系统。依据控制系统理论,建立了棱镜式激光陀螺光强控制系统传递函数。用实验测试的方法建立了环形激光器在光强控制系统中的等效数学模型,通过理论分析和Matlab仿真,能够准确评估激光陀螺光强控制系统的性能,为系统设计提供了理论依据,提高了陀螺性能和调试效率。The light intensity control system and the cavity length control system are used in the design of the laser gyro. Transfer functions of the light intensity control system of prism laser gyros are established based on the theory of the control system. The equivalent mathematical model of the ring laser in the light intensity control system is established by experiments and tests. Based on theoretical analysis and Matlab simulation, performance of the laser gyro light intensity control system can be evaluated accurately. It offers theoretic base for system design and improves performance of the laser gyro and debugging efficiency.
