摘 要:针对即热式电热水器的温度控制不佳的问题,本设计提出了用模糊控制来解决这一问题。本文在硬件部分主要应用单片机中的AT89S52作为硬件设计部分的核心器件,重要的是软件部分模糊控制器的设计,通过调试模糊控制器的设计,使设计的模糊控制器实现对即热式电热水器的温度控制,达到对温度控制的调节时间小,温度的控制精度高。利用模糊控制,设计的模糊PD控制系统,对系统进行仿真,从模糊PD控制系统的仿真结果表明,模糊控制器对即热式电热水器的控制系统工作比较稳定,控制的效果比较好,过渡的过程比较短。 37549 毕业论文关键词:模糊控制;即热式电热水器;模糊PD控制
The System Design of Fuzzy Temperature Control of the Electric Water Heater
Abstract: This article put forward fuzzy theory aiming at the poorly temperature controlling problems of instant water heater.In this paper, the AT89S52 microcontroller is the core device of hardware part, and the main part of software is the fuzzy controller. Through debugging the fuzzy controller, people can make it possible to control the temperature of instant water heater, even to achieve the purpose of less regulation time and higher precision of temperature controlling. Through the results of the simulation of the fuzzy PD control system, we can see that the system, of which controlling the temperature of instant water heater through fuzzy controller, is very steady, the result is pretty satisfactory and the process of transition has often proven short.
