文档介绍：摘要
随着现代压力控制技术的发展,人们对压力控制系统的控制精度越来越高。在工业生产中,铁红回转窑的窑尾压力控制也直接关系到铁红产品的产量和质量。单片微机在许多过程控制设备和产品中都得到广泛的应用。由于其体积小,价格低,具有逻辑判断、定时计数、程序控制等多种功能,在各个领域、各个行叶,使用单片机控制压力是很常见的一种方式。
首先对回转窑压力技术的研究背景与发展现状进行论述,并且分析了其研究进展以及技术要求,然后设计了一个基于单片机回转窑窑尾压力系统。此系统对硬件进行了具体的设计和相关软件流程的设计,而且对所选的模糊PID控制算法进行了MATLAB仿真。
最后研究了基于单片机模糊PID控制系统的优点。并且根据仿真实验结果,对控制系统的性能给出了分析评价。

ABSTRACT
With the development of modern pressure control technology, people pay more and more attentions to the precision of control pressure system. In modern industrial production, the pressure control of iron oxide rotary kiln is also directly related to the product yield and quality of the iron oxide. Single-chip puters are widely used in many process control equipment and products. Because of its small size, low price and logical judgments, time counting, process control and other functions, it is mon method to control the system by the puters in various fields.
Firstly, the technology research background and current development of the pressure on the rotary kiln and analysis of its research and technical requirements are mentioned, then a system based on single chip of pressure rotary kiln
is designed. This system is specifically designed on hardware and related software flows are given, and the control algorithm of fuzzy-PID is simulated by MATLAB.
Finally, the advantages of puter control system are analyzed, and the accuracy of analysis and evaluation based on simulation results are evaluated..
Keyword: iron oxide, rotary kiln, Single-chip puter, fuzzy-PID control
