摘　　要：随着现代电子控制技术高速发展,温度是一种最基本的环境参数。本文介绍了模糊控制的基本原理,以89S52单片机作为控制内核,采用温范围宽,精度高的铂热电阻及12位逐次比较式A/D转化器AD574A,运用模糊控制算法设计温控仪实现如下要求:通过键盘设定所需温度;显示当前温度和设定温度。经实验研究表明,该设计方案合理,功能满足设计要求。With the high speed of modern electronic control technology development, the temperature is a basic environmental parameters. This paper introduces the basic principles of fuzzy control, as control 89 S52 MCU cores, using temperature range and high precision platinum resistance and heat 12 successive comparison A / D converter AD574A using fuzzy control algorithm design temperature controller to achieve the following requirements:keyboard settings for temperature;showed that the current temperature and temperature conditions. The experimental study show that the design of rational, functional meet design requirements.
