光纤陀螺(FOG)作为一种新型角速度传感器正在飞速发展。SLD(超辐射二极管)光 源的稳定性对光纤陀螺的性能有极其重要的影响。从分析SLD 的特性及FOG 对其驱动控制的要求出发,提出了几种驱动控制实现方案,并对其可行性进行验证。 关 键 词:光纤陀螺;SLD;光控;模糊控制 Abstract: As a new type of rotation sensor, the fiber-optic gyro (FOG) is rapidly developed. The stability of SLD light source has very important effect on the performances of FOG. From the analysis of characteristics of SLD and the FOG’s request for driving control, the paper provides several schemes for the realization of driving control, and validates their feasibilities. Key words: fiber-optic gyro; SLD; light power control; fuzzy control
