摘　　要：环境温度是影响半导体温控的关键参数,实验表明常规模糊PID在应对大的环境温度斜率时鲁棒性能无法满足正常工作需求。针对这一问题,设计了一种新的环境适应型模糊PID控制方法,在原有的控制基础上加入基于环境温度信号反馈的模糊PID初值校正模块,并利用MATLAB对系统进行了仿真,最后在半导体激光温控平台上进行了实验验证。结果显示:相比普通的模糊控制算法,在大的环境温度斜率下,可以实现误差在±0.1℃内的稳定控制,鲁棒性明显提升。Ambient temperature is a key parameter affecting semiconductor temperature control.Experiments show that the robust performance of conventional fuzzy PID can’t meet the normal working requirements when dealing with large ambient temperature slope. Aiming at this problem,this paper designs a new environment-adapted fuzzy PID control method. Based on the original control,a fuzzy PID initial value correction module based on ambient temperature signal feedback is added,and the system is simulated and analyzed by MATLAB. Finally, the experimental verification was carried out on the semiconductor laser temperature control platform. The results show that compared with the common fuzzy control algorithm,under the large ambient temperature slope,the system can achieve stable control with error within ±0.1 ℃, and the robustness is obviously improved.
