摘　　要：本文介绍了一种基于AT89S52单片机的电阻炉温度控制系统,阐述了系统的工作原理、硬件电路以及软件设计。详细论述了数字PID控制器的原理及其在电阻炉温控系统中的应用,采用Ziegler—Nichols参数整定法与经验法对PID控制参数进行整定,并且在PC机上开发了一套温度监控软件,通过串口实时监控系统的温度。该系统经过实验,取得了较为满意的控制效果。　This article introduces a temperature control system based on AT89S52 Single Chip Microcomputer. The system control principle, the hardware and software are presented. The digital PID controller and its application on the temperature control system of resistance furnace are discussed in detail. Using parameters Ziegler—Nichols turning and the principle of experience to tune the parameters of PID controller, and a real- time supervisory control software was developed on the computer. The system was tested with resistance furnace, the result showed that this system could achieve quite good control performance.
