毕业设计（论文）PID温度控制摘要模糊PID的温度控制系统具有真正的智能化和灵活性，越来越多的温度控制系统都基于模糊PID算法而设计。随着控制对象变得复杂，应用常规PID温度控制精度和鲁棒性降低。当控制对象很复杂的情况下，常规PID温度控制器已经不再适用了，为了提高对复杂系统的控制性能，要使用模糊PID温度控制器。一种将PID控制与模糊控制的简便性、灵活性、以及鲁棒性融为一体，构造了一个模糊PID温度控制器。本文设计了一种基于模糊PID的温度控制系统，以AT89C51单片机为核心，主要做了如下几方面的工作：首先介绍了模糊PID控制理论基础，其次进行系统的硬件设计以及硬件选择，最后进行系统的软件设计以及仿真。关键词：模糊PID；AT89C51单片机；温度控制；仿真AbstractFuzzy PID temperature control system with real intelligence and flexibility, more and more temperature control systems are designed based on fuzzy PID algorithm.With the control object becomes complicated, using conventional PID temperature control accuracy and robustness of the lower.When the control object is a complex situation, conventional PID temperature controller is no longer applied, in order to improve the control performance of complex systems, to use the fuzzy PID temperature controller.A way to PID control and fuzzy control of simplicity, flexibility, and robustness of the integration, we constructed a fuzzy PID temperature controller.This design presents a fuzzy-based PID temperature control system to AT89C51 SCM,made the following main areas of work:first introduce the theory of fuzzy PID control,second for the hardware design and hardware design,and finally to the system software design and simulation.Keywords: Fuzzy PID; AT89C51 SCM; temperature control; simulation目 录TOC \o 1-3 \h \u HYPERLINK \l _Toc19054 第一章 绪论 PAGEREF _Toc19054 1 HYPERLINK \l _Toc5571 1.1选题背景及其意义 PAGEREF _Toc5571 1 HYPERLINK \l _Toc23881 1.2概述 PAGEREF _Toc23881 1 HYPERLINK \l _Toc14744 1.3温度测控技术的发展与现状 PAGEREF _Toc14744 1 HYPERLINK \l _Toc15802 1.3.1定值开关控温法 PAGEREF _Toc15802 2 HYPERLINK \l _Toc4377 1.3.2PID线性控温法 PAGEREF _Toc4377 2 HYPERLINK \l _Toc14041 1.3.3智能温度控制法 PAGEREF _Toc14041 2 HYPERLINK \l _Toc26735 第二章 模糊PID控制理论 PAGEREF _Toc26735 4 HYPERLINK \l _Toc9177 2.1PID控制器 PAGEREF _Toc9177 4 HYPERLINK \l _Toc5893 2.1.1PID控制的发展 PAGEREF _Toc5893 4 HYPERLINK \l _Toc19315 2.1.2PID控制理论 PAGEREF _Toc19315 4 HYPERLINK \l _Toc18882 2.1
