热电制冷器的模糊PID恒温控制器的研制

The Design of The Thermoelectric Refrigeration,s Fuzzy PID Constant Temperature Controller

本文介绍了一种利用ARM、改进的buck变换器和数字温度传感器DS18B20,采用模糊PID控制算法构成的恒温控制器。该控制器所控温度与环境温差最大可达30°C,所控温度精度达±0.5°C。

This paper discusses a constant temperature controller which uses ARM、modified buck converter、numeric temperatrure sen- sor DS18B20 and fuzzy PID control arithmetic.The maximum difference temperature of the controller and the environment temperature is 30 degree centigrade,the temperature precision which it controlls is ±0.5 degree centigrade.
