Igikoresho cyo kugenzura moteri y'imodoka ni iki?
Igenzura rya moteri y'imodoka (MCU) ni module y'ingenzi y'ikoranabuhanga y'ibinyabiziga bishya bitanga ingufu, iri hagati ya bateri y'amashanyarazi na moteri itwara. Ishinzwe cyane cyane guhindura umuriro utaziguye mo umuriro usimburana kugira ngo moteri ikore, no guhindura umuvuduko wa moteri, imbaraga n'icyerekezo byayo hakurikijwe amabwiriza yo kuyitwara, kugenzura uko imodoka itangira, kwihuta, gufunga feri, kuzamuka n'ibindi bipimo byo kuyitwara.
Imikorere y'ibanze
Guhindura Voltage ya Youdaoplaceholder0 : Hindura amashanyarazi aturuka kuri batiri y'amashanyarazi mu mashini ihinduranya ingufu y'ibice bitatu kugira ngo itware moteri ya AC. Iyi nzira igerwaho binyuze muri inverter y'imbere, ikoresha ibikoresho byo guhinduranya ibikoresho nka transistors cyangwa IGBTs kugira ngo igenzure ingano n'ubwinshi bw'amashanyarazi.
Youdaoplaceholder0 Umuvuduko n'igenzura rya torque : Hindura umuvuduko wa moteri n'igenzura rya torque hakurikijwe ibisabwa mu gutwara (nk'aho imodoka ihagaze, umuvuduko w'amashanyarazi, feri), kandi ugenzure neza binyuze mu ikoranabuhanga rya PWM (pulse width modulation).
Uburinzi bwa sisitemu ya Youdaoplaceholder0 : Ifite uburinzi bw'umubyigano, kumenya amakosa, uburinzi bw'aho bateri yinjira n'ubundi buryo bwo kugenzura imikorere myiza ya sisitemu.
Youdaoplaceholder0 Kugarura ingufu : Mu gihe cyo gufunga feri, ingufu za kinetiki zishobora guhindurwamo ingufu z'amashanyarazi binyuze mu buryo bwa inverter kugira ngo bateri isharishwe, bityo byongera urwego rwo kuyitwara.
Ibice by'ingenzi
Module yo kugenzura ya Youdaoplaceholder0 : Itunganya amabwiriza yo gutwara no gukora ibimenyetso bya PWM kugira ngo igenzure inverter.
Module y'amashanyarazi ya Youdaoplaceholder0 : Irimo IGBT n'ibindi bice by'ingufu kugira ngo ihindure voltage.
Sensoreri ya Youdaoplaceholder0 : igenzura imiterere ya moteri (nk'ubushyuhe, umuvuduko) hanyuma ikayisubiza kuri sisitemu yo kuyigenzura.
Sisitemu yo gukwirakwiza ubushyuhe ya Youdaoplaceholder0 : igumana ubushyuhe buhamye mu gihe cy'imizigo myinshi.
Imikorere y'umugenzuzi wa moteri igira ingaruka zitaziguye ku bunararibonye bwo gutwara no gukoresha neza ingufu z'imodoka zikoresha amashanyarazi, kandi ni ihuriro ry'ingenzi rihuza bateri y'amashanyarazi na moteri itwara.
Igenzura rya moteri y'imodoka ni igice cy'ingenzi cy'imodoka zikoresha amashanyarazi, kandi inshingano zayo z'ingenzi zirimo:
Kugenzura umuvuduko n'imbaraga z'amashanyarazi
Umuvuduko wa moteri n'umuvuduko wayo bihindurwa hakurikijwe amabwiriza nka accelerator na feri. Voltage n'umuvuduko bigenzurwa binyuze mu ikoranabuhanga rya PWM kugira ngo bigerweho amabwiriza nyayo y'umuvuduko, bihuze n'ibisabwa mu gutwara nk'umuvuduko, feri, n'imisozi izamuka.
Guhindura ingufu no kuzikoresha
Umuriro utaziguye uva muri batiri y'ingufu uhindurwamo umuriro usimburana kugira ngo utware moteri, kandi icyerekezo cy'umuriro gihindurwa binyuze muri inverter kugira ngo kigenzure uko moteri izunguruka imbere n'inyuma. Iyo feri ihagaze, ingufu za kinetiki zishobora guhindurwamo ingufu z'amashanyarazi zikazanwa muri batiri.
Kurinda no gusuzuma sisitemu
Kugenzura ibipimo nk'ubushyuhe bwa moteri n'amashanyarazi, gusuzuma amakosa mu gihe nyacyo (nk'ubushyuhe bukabije n'umubyimba mwinshi), no gufata ingamba zo kwirinda kwangirika. Muri icyo gihe, vugana kandi usangize amakuru n'izindi sisitemu (nka BMS) ukoresheje umuyoboro wa CAN.
Igenzura ry'ibisubizo bihinduka
Torque na magnetic flux bihindurwa ku giti cyabyo binyuze muri algorithme zo kugenzura vector kugira ngo bigerweho vuba ku mabwiriza yo gutwara. Guhinduranya neza mu gihe cyo gutangira/guhagarara kugira ngo bigabanye ibyiyumvo byo gutungurwa.
Amakosa y'umugenzuzi wa moteri mu binyabiziga bishya bitanga ingufu agaragara cyane cyane nko kugabanuka k'ubushobozi bw'ingufu, gutangira bigoranye, kongera ikoreshwa ry'ingufu n'ibindi bibazo. Impamvu zihariye zigomba gupimwa neza hamwe n'ingaruka z'amakosa.
Ibimenyetso bisanzwe by'amakosa
Youdaoplaceholder0 Ingufu zigabanuka : Ipineri y'umuvuduko isubiza buhoro buhoro, bigatuma bigora imodoka kwihuta kandi ikagabanya umuvuduko ntarengwa.
Youdaoplaceholder0 Gutangira kudasanzwe : Hashobora kubaho ingorane mu gutangira, kugerageza gutangira inshuro nyinshi byananiranye, cyangwa amajwi/imitingito idasanzwe mu gihe cyo gutangira.
Youdaoplaceholder0 Kongera ikoreshwa ry'ingufu : Kunanirwa kwa controller bishobora gutuma moteri igabanuka kandi imodoka ikagira igihe gito cyo gukora.
Youdaoplaceholder0 Itara ryerekana amakosa : Agasanduku k'ibikoresho kerekana itara ry'ikosa rya sisitemu y'amashanyarazi cyangwa itara ry'ikosa rya sisitemu ya moteri.
Uburyo bwo gusuzuma amakosa
Youdaoplaceholder0 Ibizamini by'ibanze :
Reba niba voltage y'amashanyarazi ari isanzwe (koresha multimeter kugira ngo upime niba voltage ya 5V idasanzwe)
Reba niba hari ikintu gishyushye cyane mu muyoboro mukuru w'icyuma gipima (imiyoboro 6 ya MOS switch)
Kumenya ikimenyetso cya Youdaoplaceholder0 :
Pima impinduka z'amashanyarazi mu gihe uzungurutsa umugozi (urugero rusanzwe: 0-4.2VDC)
Reba niba insinga zihuza zidafunguye cyangwa zashaje
Ikizamini gishya cya Youdaoplaceholder0 :
Iyo imbaraga zo gukandagira zibuze nyuma yo gutandukanya imirongo itatu minini ya moteri, bishobora kuba ari ikibazo cy'umugenzuzi
Koresha ibikoresho by'umwuga (nk'icyuma gipima byinshi) kugira ngo ugerageze ibipimo nka diode na voltage yo gufata
Isesengura ry'Impamvu z'Amakosa
Youdaoplaceholder0 Kwangirika kw'ibikoresho : Kwangirika k'ibikoresho by'amashanyarazi byo mu nzu (nk'ibice bya IGBT)
Ikibazo cyo guhuza Youdaoplaceholder0 : Imirongo y'ibimenyetso idafite ishingiro kandi yashaje itera kubura ibimenyetso byo kugenzura
Youdaoplaceholder0 Inenge mu gishushanyo : imiterere idahagije yo gukwirakwiza ubushyuhe cyangwa imiterere idahwitse y'ibipimo by'urukiramende
Niba ushaka kumenya byinshi, komeza usome izindi nkuru kuri uru rubuga!
Duhamagare niba ukeneye ibyo bicuruzwa.
