A Design of Fuzzy-PID Controller of Constant Temperature for Semiconductor Laser Diodes

Abstract

The paper introduces two types of precise temperature controllers for high power semiconductor laser diodes. We apply a category of self-tuning parameter fuzzy-PID controller and a kind of neuronal network optimized rules fuzzy-PID controller to realize stable temperature controlling. Also we simulate this two methods using Matlab. The result proves that the new method has more superiority than traditional means, such as PID controlling, etc. And further improvement on constant temperature control will inevitably promote the reliability of LD.
