I摘要隨著電力電子技術(shù)、微電子技術(shù)及控制理論的發(fā)展，電氣控制系統(tǒng)在工程中得到日益廣泛的應(yīng)用。劍桿織機作為一種適應(yīng)性最強的無梭織機，其發(fā)展方向為電子選緯、電子送經(jīng)、電子卷取控制技術(shù)的研究和應(yīng)用。本論文采用DSP2407作為劍桿織機電氣控制系統(tǒng)的主控芯片。并對主要組成部分進行了較為系統(tǒng)的闡述，包括送經(jīng)卷取系統(tǒng)，引緯系統(tǒng)及其電機的驅(qū)動控制，故障檢測做出具體的分析，同時對劍桿織機的經(jīng)紗張力做出檢測并及時反映給單片機。送經(jīng)卷取電機采用無刷直流電機來完成，并在微處理器的控制下實現(xiàn)送經(jīng)卷取的同步運行，保持張力恒定。引緯電機采用三相混合式步進電機。本文首先對紡織機和其電控部分的總體設(shè)計做出概述，然后是設(shè)計的主體部分，首先是對三相電的整流，濾波做出設(shè)計并進行整流二極管和濾波電容的選擇。本文對送經(jīng)卷取電機和引緯電機都使用雙極性PWM控制，選取MOSFET作為橋式逆變的開關(guān)器件。送經(jīng)電機部分選用驅(qū)動芯片IR2113來驅(qū)動開關(guān)器件。同時對電路進行檢測，本文對整流輸出母線電壓和送經(jīng)電機定子短接電流進行檢測經(jīng)A/D轉(zhuǎn)換將信號傳給控制芯片。引緯部分對三相混合式步進電機的驅(qū)動和檢測做了詳細設(shè)計。設(shè)計中采用“S”型張力傳感器對經(jīng)紗張力進行檢測，將檢測信號傳遞給控制芯片進行處理，若張力超過限定值則發(fā)出停車信號。再次是軟件設(shè)計部分對織機控制主程序，張力調(diào)節(jié)子程序和送經(jīng)電機啟動子程序做出設(shè)計。在文章的最后應(yīng)用MATLAB對PWM逆變和無刷直流電機的控制部分進行仿真。關(guān)鍵詞劍桿織機無刷直流電機三相混合式步進電機驅(qū)動IIAbstractWiththepowerelectronics,microelectronicsandcontroltheoryofthedevelopment,electricalcontrolsystemincreasinglywidelyinengineeringapplications.Asamostadaptablerapierinloom,itsdirectionfortheelectronicweft,electroniclet-off,e-coilingcontroltechnologyresearchandapplication.Inthisthesis,DSP2407ascontrolchipelectricalcontrolsystemofrapierchip.Andthemaincomponentofamoresystematicexposition,includingthedeliverybythetake-upsystem,theweftinsertionsystemanditsmotordrivecontrol,faultdetectionandmakespecificanalysis,whilethetensionontheloomtomakedetectionofthewarpandpromptlyreflectedtothemicrocontroller.Sentbythetake-upmotorwithbrushlessDCmotortocomplete,andunderthecontrolofthemicroprocessortoachievesynchronousoperationsentbythetake-up,maintainconstanttension.Weftchiocethree-phasehybridsteppingmotormotor.Firstly,thetextilemachineandelectriccontrolpartofitsoveralldesignmadetomakeanoverview,andthenthemainpartofthedesign,thefirstofthethree-phaserectifier,thefilterwasdesignedandcalculatedtomaketheselectionofrectifierdiodesandfiltercapacitorselection.Inthispaper,sentbythetake-upmotorandweftareusingbipolarPWMmotorcontrol,selecttheMOSFETasabridgeinverterswitchingdevices.SentbythemotorpartoftheIR2113driverchipusedtodrivetheswitchingdevices.Whiletestingthecircuit,therectifieroutputpapersentbythebusvoltageandshortcircuitstatorcurrentwasdetectedbytheA/Dconversionsignalstocontrolchip.Weftpartofathree-phasehybridsteppingmotordrivedesignandtestingindetail.DesignbySTypeTensionroadwarptensionsensordetection,willdetectthesignalstocontrolchipDSPprocessing,ifthetensionexceedsthelimitvalueofthestopsignalisissued.Forthesoftwaredesignpartonthemainloomcontrol,tensionadjustmentandlet-offmotorstarterssubroutinesubroutinetomakethedesign.ApplicationofMATLABtothePWMinverterandbrushlessDCmotorcontrolpartofthesimulation.KeywordsrapierbrushlessDCmotorhybridsteppingmotordriverIII目錄摘要.IAbstract.II第1章緒論.71.1紡織機的概述.71.1.1紡織業(yè)的發(fā)展.71.1.2紡織機的概念及分類.81.2劍桿織機發(fā)展趨勢.91.3紡織機中自動控制的應(yīng)用.10第2章自動紡織機電控系統(tǒng)設(shè)計方案.112.1織機的基本組成部分和織造原理.112.2織機電控系統(tǒng)設(shè)計.13第3章硬件設(shè)計.I3.1送經(jīng)卷取控制系統(tǒng)設(shè)計.153.2送經(jīng)電機的選取.153.3送經(jīng)電機驅(qū)動設(shè)計.173.3.1整流電路設(shè)計.183.3.2逆變電路設(shè)計.193.3.3驅(qū)動電路設(shè)計.203.4檢測電路.213.4.1電機電流檢測電路.213.4.2整流輸出電壓監(jiān)測電路.233.4.3轉(zhuǎn)子位置檢測電路.233.5引緯系統(tǒng).253.5.1引緯電機的選擇.253.5.2步進電機的驅(qū)動控制.263.5.3MOSFET的驅(qū)動電路.273.5.4步進電機電流檢測電路.283.6張力信號測量電路設(shè)計.28IV3.7剎車系統(tǒng)設(shè)計.293.8電源設(shè)
