毕业设计（论文） 题 目 电加热炉温度控制系统模型建立及控制算法 英文题目 The Electric Heating Furnace Temperature Control System Models and Control Algorithms to Establish 学生姓名 专 业 自动化 班 级 指导教师 二零零六年六月 摘要 本文以电加热炉为控制对象.通过对电加热炉对象特性的分析来确定电加热炉系统的构成及控制方案。而这里主要采用的设计方案是普通电加热炉温度控制系统模型建立及控制算法,8051单片机组成系统。此外由于PIDPID控制算法。本文还建立电加热炉数学模型。此外在论文中也介绍了史密斯预估方案，以及关于占空比，这两个问题都有在论文中提到，其中史密斯预估方案对系统的稳态性能影响很大，而占空比问题也对系统温度加热时间有很大关系。出此之外，论文中还介绍了电加热炉温度控制系统中要运用到的主要芯片.以及这些芯片在系统中的各自功能也都有介绍。 此论文重点讨论了电加热炉温度控制系统系统的控制算法， 关键词 电加热炉；温度控制；单片机；PID算法; Abstract This method resolves the Electrical-heated furnace is the controlled target .By analyzing the characteristic of electrical-heated furnace control system. Under this condition We choose the chief in the article is the contradiction between static and dynamic performances, the computer control system for controlling the stove temperature adopt the expert system and its deficiencies are complex and has much interference .this system is easily implemented. the most important in this design is that the electric heating elements, control algorithm, and soft-ware design of the system .Besides,this methord introduce selectrical-heated by maths. And also introduce about the O.J.M des Smith’idea.And also introduce other things about this method. In the method we also can find about the chip about the design ,it also includes the function about the chip. The ideas in the method what had been mentioned are all very important for me to design this method .The results of algorithm simulation prove that single neuron adaptive PSD intelligent control algorithm is simple and its effect is the better .it has very high theoretical value and practical value. The most important mental in this method is how to design the selectrical-heated by PID algorithm Key words selectrical-heated furnace; temperature control; Single chip micyoco; PID algorithm.  目录 中文摘要与关键词 英文摘要与关键词 绪论………………………………………………………………………………………1 1. 电加热炉温度控制系统的构成 …………………………………………………….2 1.1 各个主要元件电加热炉温度控制
