智能控制在光纤陀螺光源稳定控制中的应用

The application of intelligent control on light source stability of FOG

根据光纤陀螺(FOG)对超辐射发光二极管(SLD)光源输出光功率的稳定性要求,针对目前SLD光源一致性差的特点,提出Fuzzy PID控制的光控实现方案。经验证,该智能光功率闭环控制能灵活调整SLD期望输出光功率值,不仅能实现SLD在宽温度范围内保持较高的光功率稳定性,且系统具有较强的鲁棒性。

According to the stability request of light power output of SLD light source for FOG,and considering the inconsistent characteristics of SLD,this thesis puts forward a light control plan with FuzzyPID control.As show in the experiments,the intelligent light power closed loop control can not only easily adjust the expectant light power output of SLD,but also keep high stability of light power in broad temperature range and strong robustness of system.
