传感器在模糊控制洗衣机中的应用研究第I页传感器在模糊控制洗衣机中的应用研究摘要模糊控制是首先对控制对象按照人们的经验总结出模糊规则,然后由单片机对这些信息按照模糊规则做出决策来完成自动控制。首先，本文将概述模糊控制的基本原理和特点，并研究模糊控制在洗衣机中的应用方面。例如，在洗涤衣物过程中，衣物的多少，面料的软硬等都是模糊量，所以首先做大量的实验，总结出人为的洗涤方式，从而形成模糊控制规则。其次，本文将根据模糊控制原理对洗衣机的水位控制进行具体的研究，具体主要是模糊传感器的应用，即利用模糊传感器实现对洗衣机水位的测量，并把得到的数据经单片机A/D转换后，输出结果。最后，通过MATLAB仿真器在实际设计中的应用，模拟研究是模糊洗衣机加水和排水的模糊控制。通过建立模糊推理系统，完成模拟量的函数关系及函数图像，验证得出模糊传感器较以往的传感器更加智能化，便捷化，为人们的生活节约了许多不必要的麻烦。关键词：模糊控制，隶属度函数，模糊推理系统，模糊传感器第II页TheSensorsappliedresearchinthefuzzycontrolofwashingmachinesAuthor：ZhangdanyangTutor：HejintianAbstractAccordingtopeople'sexperience,thefuzzycontrolsummarizesthefuzzyruletothecontrolledmemberatfirst,andthenaccordingtothefuzzyrule,itmakesthedecision-makingtocompletetheautomaticcontrolbythemonolithicintegratedcircuittothisinformation.First,thisarticlewilloutlinethefuzzycontrolthebasicprincipleandthecharacteristic,andelaboratesthefuzzycontrolinwasher'sapplicationaspect.Forexample,intheclothingwashingprocess,thefuzzyquantitycontainshowmanyclothing's,theliningsoftorhardandsoon,thereforefirstdoesthemassiveexperiments,andsummarizestheartificialwashway,thusformsthefuzzycontrolrule.Next,accordingtothefuzzycontrolthisarticlewillactprincipletoconducttheconcreteresearchtowasher'swatermonitor,whichismainlythefuzzysensor'sapplicationspecifically,namelytheusefuzzysensorrealizestothewasherwaterlevelsurvey,andthedatawhichobtainsafterthemonolithicintegratedcircuitA/Dtransformationwillbeputout.Finally,thesimulatorstudyisthefuzzywasherwateringandthedrainingwaterfuzzycontrolthroughtheMATLABsimulator'sinactualdesignapplication.Throughtheestablishmentfuzzyreasoningsystem,thesimulationquantitycompletesthefunctionalrelationsandthefunctionimage,andtheconfirmationobtainsthefuzzysensorformersensormoreintellectualized,convenient,savedmanynonessentialtroublesforpeople'slife.Keywords:Fuzzycontrol,Membershipfunction,fuzzyinferencesystem，Fuzzysensor第III页目录1绪论................................................................................................................................11.1课题背景及目的......................................................................................................11.2国内外研究情况......................................................................................................11.3课题研究方法..........................................................................................................21.4论文构成及研究内容..............................................................................................32模糊控制及相关知识.......................................................................................................42.1模糊语言的符号描述..............................................................................................42.2模糊控制的基础知识..............................................................................................52.2.1模糊传感器的基础知识...............................................................................52.2.2模糊传感器的实现方法...............................................................................52.2.3FOULLOY算法简介.......................................................................................63模糊洗衣机的水位控制设计..........................................................................................83.1模糊控制洗衣机的工作流程..................................................................................83.2模糊洗衣机的水位控制的研究设计过程..............................................................83.3传感器的选择与应用..............................................................................................93.3.1由集成硅压力传感器MPX5100A构成的压力调节系统..........................93.3.2MAX1463数字传感器信号处理器...........................................................103.3.3压力传感器测量电路.................................................................................103.3.4传感器电桥工作原理.................................................................................113.4定量分析和计算....................................................................................................113.4.1测量电路和量程调整..................................................................................113.4.2零点调整和迁移电路.................................................................................123.5单片机ADC0809...................................................................................................133.5.1芯片简介.....................................................................................................133.5.2元件设计连线.............................................................................................133.5.3原理图.........................................................................................................14第IV页3.6运用MATALAB实现的水位控制仿真...............................................................143.6.1建立模糊推理系统(FIS)...........................................................................153.6.2模糊控制的SIMULINK仿真......................................................................163.6.3洗衣机水缸加水时的SIMULINK仿真......................................................163.6.4洗衣机洗涤加水和排水SIMULINK仿真..................................................17结论...
