基于模糊自整定PID算法的太阳能热水器控制系统研究

Control System of Solar Water Heater Based on Fuzzy Self-tuning PID Algorithm

为解决目前国内市场上的太阳能热水器控制系统功能单一、抗干扰能力差的问题,以微处理器为控制器核心,根据比例因子模糊自整定PID控制算法设计控制程序,采用模块化方式进行了软硬件结合,设计了一种太阳能热水器智能控制系统。对系统供热模型和模糊自整定PID算法进行了深入的分析,在此基础上设计了温度采集、显示和智能控制系统,并对硬件和软件设计做了一定的介绍,最后通过实验验证了该控制器的应用效果。

This paper chooses microprocessor as the core,and designs an intelligent control system for solar water heater.In the system,PID control algorithm based on the proportional factor fuzzy self-tuning is used to the control program,and the method of modular design is adopted in the combination of hardware and software.In this paper,the thermal model and fuzzy self-tuning PID algorithm are analyzed,the temperature collection,display and intelligent control system is designed,and the hardware and software design of the system are introduced.
