论文题目：模糊控制在智能温度控制系统中的应用摘要温度系统惯性大、滞后现象严重，难以建立精确的数学模型，给控制过程带来很大难题。本文以电锅炉为研究对象，研究一种最佳的控制方案，以达到系统稳定、调节时间短且超调量小的性能指标。将模糊控制的智能性与PID控制的通用性、可靠性相互结合，设计了一种参数自整定模糊PID控制器，采用模糊推理的方法实现PID参数的在线整定。经仿真研究，参数自整定模糊PID控制效果达到了电锅炉温度控制系统的性能指标，是一种较为理想的智能性控制方案。在分析电锅炉供暖系统对控制器要求的基础上，研制了单片机为核心部件的温度智能控制器，实现了温度的采集与控制、超限报警等各种功能。在进行硬件电路设计的同时，也进行了相应软件设计，并将本文所提出的模糊PID算法引入到软件设计中，给出了主程序流程图、模糊PID算法工作流程图和温度采集流程图等。关键词：电锅炉温度控制模糊PID控制控制算法仿真FuzzyControlinIntelligentTemperatureControlSystemABSTRACTFortheinertiaandseriouslag,itisdifficulttoestablishaccuratemathematicalmodelandcontroltheprocessoftemperaturesystem.Thispaperselectselectricboilerastheresearchobjectinordertofindanoptimalcontrolschemetoachievesystemstability,shortsettlingtimeandsmallovershootperformance.IntegratetheintelligenceoffuzzycontrolwiththeversatilityandreliabilityofPIDcontrolonthebasisofwhichIdesignaparameterself-tuningfuzzyPIDcontrollerusingfuzzyreasoningmethodtoaccomplishonlinetuningPIDparameters.ExperimentalresultsillustratethatthefuzzyPIDparameterscontrollerachievedthesystemperformanceindex.ThemethodoffuzzyPIDcontrolisaidealmethod.Inthisthesis,basingontherequestoftheelectricboilerheatingsystemtothecontroller,atemperaturecontrolleroftheelectricboilerisdesigned,inwhichthe8051isused.Itsperformanceinclude:temperaturegathering,algorithmrealization,warning,etc.Thehardwarecircuitisdesignedandthecorrespondingprocedureflowchartisalsodesigned,suchasmainprogramflowchart,fuzzyPIDworkingflowchartandtemperaturecollectionflowchart.Keywords:ElectricBoilerTemperatureControlFuzzyPIDControlSimulation目录1绪论............................................................................................................................11.1选题的目的及意义.............................................................................................11.2国内外温度控制研究现状.................................................................................12系统模型及硬件电路设计........................................................................................22.1被控对象分析.....................................................................................................22.2电锅炉温度控制系统的模型.............................................................................32.3硬件设计.............................................................................................................32.3.1硬件设计概述..............................................................................................32.3.2单片机的选择..............................................................................................42.3.3温度传感器DS18B20.................................................................................62.3.4功率放大模块..............................................................................................82.3.5数据采集模块..............................................................................................82.3.6控制输出模块........................................
