电阻炉温度控制系统设计本科毕设论文.doc

题目：电阻炉温度控制系统设计）电阻炉温度控制系统设计摘要随着科学技术的飞速发展，控制理论不断丰富和完善，控制技术也在向智能化、开放性、高可靠性的方向发展。目前常用的控制方式有智能化仪表、PLC、DCS，它们可组成各种控制系统以满足不同的控制要求。其功能越来越强大、性能也越来越完善，并具有控制精度高、抗干扰能力强、防爆性强等特点。本文研究的是电阻炉的温度控制系统，由于电阻炉在生产和生活中的应用比较广泛，所以电阻炉的温度控制就显得尤为重要了。建立一个控制系统首先要针对控制对象进行研究，本设计的研究对象是实验室现有的管式电阻炉，因此本文对其进行了对象性能测试。然后针对电阻炉的特点，提出了利用数字调节器、固态继电器等器件组成温度控制系统，通过调节参数实现对电阻炉温度的控制。这种方法经济、简单、易操作，控制精度高。最主要的是：学会了利用实验室现有的设备去掌握设计一个控制系统，更深刻的理解设计控制系统的思想，为以后的学习、工作打下了坚实的基础。关键词：电阻炉；对象特性测试；控制系统；PWM；调节器ResistancefurnacetemperaturecontrolsystemAbstractAlongwithscience'sandtechnology'sswiftdevelopment,thecontroltheoryisunceasinglyrichandisperfect,thecontroltechnologyalsototheintellectualization,openness,theredundantreliabledirectiondevelops.Atpresentthecommonlyusedcontrolmodehastheintellectualizedmeasuringappliance,PLC,DCS,theymaycomposeeachkindofcontrolsystemtosatisfythetechniqueofproductiontherequest.Itsfunctionisgettingmoreandmoreformidable,theperformancetobegettingmoreandmoreperfect,andhasthecontrolprecisiontobehigh,antijammingabilityisstrong,Whattheexplosion-proofstrongandsooncharacteristicthisarticlestudiesisresistancefurnace'stemperaturecontrolsystem,becauseresistancefurnaceinproducesandinthelifeapplicationisquitewidespread,thereforeresistancefurnace'stemperaturecontrolappearedespeciallyimportant,establishedacontrolsystemfirsttoaimatthecontrolledmembertoconducttheresearch.Thisdesign'sobjectofstudyisthelaboratoryexistingtubularresistancefurnace,thereforethisarticlehascarriedontheobjectperformancetesttoit.Theninviewofresistancefurnace'scharacteristic,proposedusecomponentcompositiontemperaturecontrolsystemsandsoondigitregulator,solidstaterelay,realizethroughtheadjustmentparametertotheresistancefurnacetemperaturecontrol.Thismethodeconomical,simple,easytooperate,thecontrolprecisionishigh.Whatismostmain:Graspsusingthelaboratoryexistingequipmentdesignstheworkwhichacontrolsystem,themoreprofoundunderstandingdesigncontrolsystem'sthoughtthatforthelaterstudy,theworkhasbuiltthesolidfoundation.Keyword:resistancefurna
