The development of Fabry-Perot(F-P)etalon is one of the key technologies of spaceborne scattering lidar.Based on the analysis of the influence of temperature on F-P etalon,combined with the conventional proportional-integral-derivative(PID)temperature control algorithm and fuzzy algorithm principle,a fuzzy algorithm and incremental proportional-integral-derivative(PID)algorithm with added anti-saturation parameter are proposed to achieve the control of F-P etalon temperature.The final set temperature is controlled within ±0.06 K.The algorithm is not only simple to achieve,but also has high control precision and good stability,which provides a powerful guarantee for breakthrough of narrowband optical reception of spaceborne scattering lidar.
