屆本科畢業(yè)論文（設(shè)計）論文題目：純電動汽車電控調(diào)速系統(tǒng)設(shè)計學(xué)生姓名：所在院系：所學(xué)專業(yè)：應(yīng)用電子技術(shù)教育指導(dǎo)老師：完成時間：摘要本論文以純電動汽車直流無刷電機控制器為研究目的，詳細(xì)地敘述了基于STC12C5404AD型單片機控制的PWM調(diào)速控制系統(tǒng)的設(shè)計過程。在論文中簡單介紹了單片機STC12C5404AD的結(jié)構(gòu)以及IGBT功率驅(qū)動模塊的應(yīng)用；無刷直流電機的霍爾信號與邏輯驅(qū)動信號的關(guān)系，利用此關(guān)系來控制電機的轉(zhuǎn)動和方向；另外，本論文中對電機的一些保護(hù)功能如限流保護(hù)、欠壓保護(hù)、短路保護(hù)都是利用模塊的自帶功能來實現(xiàn)的，而剎車斷電、智能巡航、自動定速、防飛車、防盜等保護(hù)功能是利用程序來實現(xiàn)，這樣使電路簡單，成本降低。除此之外，還設(shè)計了系統(tǒng)的軟件流程，包括主程序流程設(shè)計，調(diào)速子程序流程設(shè)計。關(guān)鍵詞：純電動汽車；STC12C5404AD；IGBT功率模塊；PWM控制ThepureelectricvehiclesspeedelectroniccontrolsystemdesignAbstractThisarticletakedevelopmentsthepureelectricautomobileconcurrentnottobrushtheelectricalmachinerycontrollerastheresearchgoal,narratedindetailhascontrolledthepureelectricautomobilesPWMvelocitymodulationcontrolsystemsdesignprocessbasedontheSTC12C5404ADmonolithicintegratedcircuit.ThepresentpaperintroducedthemonolithicintegratedcircuitSTC12C5404ADstructureaswellastheIGBTpoweractuationmoduleapplicationindetail；IntroducednotbrushesdirectcurrentmachinesHallsignalandlogicdrivingsignalrelations,usesthisrelationstocontrolelectricalmachinerysrotationandthedirection；Moreover,inthepresentpapertoelectricalmachineryssomeprotectionfunctionlikecurrentlimitingprotection,theundervoltageprotection,theshortcircuitprotectionisrealizesusingthemodulebringingfunction,butgetsonthebrakesthepowerfailure,theintelligentcruise,theautomaticconstantspeed,againstspeedingcar,securityandsoonprotectionfunctionsisrealizesusingtheprocedure,likethismakestheelectriccircuittobesimple,costreduction.Inaddition,butalsohasdesignedsystemssoftwareflow,includingmasterroutineflowdesign,velocitymodulationsubroutineflowdesign.Keywords:thepureelectricautomobile；STC12C5404AD；IGBTpowermodule,PWMcontrols目錄1引言.12設(shè)計方案.12.1電機的選擇.12.2控制器的選擇.22.3PWM調(diào)制方式.23系統(tǒng)結(jié)構(gòu)框圖.34單片機外圍器件的設(shè)計.44.1電源電路.44.2單片機主控制電路.44.2.1SoC型單片機STC12C5404AD.54.2.2ISP電路.64.2.3IGBT驅(qū)動模塊.74.3調(diào)速器輸入電路.74.4控制模擬器.84.5換相邏輯接口.94.6IGBT驅(qū)動電路.104.7無刷電機驅(qū)動電路.114.8防盜報警.124.9保護(hù)電路.135軟件設(shè)計與分析.135.1主程序流程圖.135.2PWM頻率.
