大功率半导体激光器温度控制系统的设计

摘要

The temperature control system needs to have high accuracy and stability for many optoelectronic applica-tions.In this paper,based on C8051 F021 microcontroller,the PID control algorithm is improved and the temperature control system of the high power semiconductor laser is designed to solve the problems of long time,low precision and poor stability of the traditional temperature control system.The experimental results show that the precision of the tem-perature control is up to ±0.1 ℃.%光电应用领域对温度控制的精确性和稳定性有很高的要求。本文基于 C8051 F021单片机，改进 PID 控制算法，设计了大功率半导体激光器温度控制系统，解决了传统大功率半导体激光器温控系统控温时间长、精度低、稳定性差等问题。实验结果表明：其控温精度可达±0.1℃。
