Ukadaulo Woyendetsa Magalimoto Othamanga Kwambiri ndi Momwe Akupangira

Ma mota othamanga kwambiriakulandira chidwi chowonjezeka chifukwa cha zabwino zake monga kuchuluka kwa mphamvu, kukula kochepa ndi kulemera, komanso kugwira ntchito bwino. Dongosolo loyendetsa bwino komanso lokhazikika ndiye chinsinsi chogwiritsa ntchito bwino ntchito yabwino kwambirima mota othamanga kwambiriNkhaniyi ikufotokoza makamaka mavuto amota yothamanga kwambirikuyendetsa ukadaulo kuchokera ku mbali za njira zowongolera, kuwerengera ngodya, ndi kapangidwe ka mphamvu, ndi kufotokozera mwachidule zotsatira za kafukufuku wamakono kunyumba ndi kunja. Pambuyo pake, imafotokoza mwachidule ndikuyembekeza chitukuko chamota yothamanga kwambiriukadaulo woyendetsa.

Gawo 02 Zomwe Zafufuzidwa

Ma mota othamanga kwambiriali ndi zabwino zambiri monga kuchuluka kwa mphamvu, kuchuluka kochepa ndi kulemera, komanso kugwira ntchito bwino kwambiri. Amagwiritsidwa ntchito kwambiri m'magawo monga ndege, chitetezo cha dziko ndi chitetezo, kupanga ndi moyo watsiku ndi tsiku, ndipo ndi ofunikira pakufufuza ndi njira yopangira zinthu masiku ano. Mu ntchito zonyamula katundu wothamanga kwambiri monga ma spindle amagetsi, makina opangira ma turbo, ma turbine ang'onoang'ono a gasi, ndi malo osungira mphamvu a flywheel, kugwiritsa ntchito ma mota othamanga kwambiri kumatha kukwaniritsa kapangidwe ka direct drive, kuchotsa zida zosinthasintha liwiro, kuchepetsa kwambiri kuchuluka, kulemera, ndi ndalama zokonzera, pomwe kumawonjezera kudalirika, ndipo kuli ndi mwayi waukulu wogwiritsa ntchito.Ma mota othamanga kwambirinthawi zambiri amatanthauza liwiro lopitirira 10kr/min kapena zovuta (zopangidwa ndi liwiro ndi muzu wa sikweya wa mphamvu) zopitirira 1 × Mota ya 105 ikuwonetsedwa mu Chithunzi 1, yomwe imayerekeza deta yoyenera ya zitsanzo zina zoyimira zamagalimoto othamanga kwambiri mdziko muno komanso padziko lonse lapansi. Mzere wocheperako mu Chithunzi 1 ndi mulingo wovuta wa 1 × 105, ndi zina zotero.

1,Mavuto mu Ukadaulo Woyendetsa Magalimoto Othamanga Kwambiri

1. Mavuto okhazikika pa dongosolo pa ma frequency apamwamba kwambiri

Pamene mota ili pamlingo wokwera kwambiri wa ma frequency oyambira, chifukwa cha zoletsa monga nthawi yosinthira analog-to-digital, nthawi yogwiritsira ntchito algorithm ya digito, komanso nthawi yosinthira inverter, ma frequency onyamula a makina oyendetsa mota othamanga kwambiri amakhala otsika, zomwe zimapangitsa kuti magwiridwe antchito a mota achepe kwambiri.

2. Vuto la kuwerengera malo a rotor molondola kwambiri pamafupipafupi oyambira

Pa nthawi yogwira ntchito yothamanga kwambiri, kulondola kwa malo a rotor ndikofunikira kwambiri pakugwira ntchito kwa mota. Chifukwa cha kudalirika kochepa, kukula kwakukulu, komanso mtengo wokwera wa masensa a malo amakina, ma algorithm opanda sensor nthawi zambiri amagwiritsidwa ntchito mumakina owongolera magalimoto othamanga kwambiri. Komabe, pansi pa mikhalidwe yayikulu yogwirira ntchito, kugwiritsa ntchito ma algorithm opanda sensor a malo kumatha kukhudzidwa ndi zinthu zosafunikira monga inverter nonlinearity, spatial harmonics, loop filters, ndi inductance parameter deviations, zomwe zimapangitsa kuti pakhale zolakwika zazikulu pakuyerekeza malo a rotor.

3. Kuletsa kugwedezeka kwa ma ripple mu makina oyendetsa mota othamanga kwambiri

Kuchepa kwa mphamvu ya injini zamagalimoto othamanga kwambiri kumabweretsa vuto la mafunde akuluakulu amagetsi. Kutayika kwa mkuwa, kutayika kwa chitsulo, mafunde amphamvu, ndi phokoso la kugwedezeka komwe kumachitika chifukwa cha mafunde amphamvu kumatha kuonjezera kwambiri kutayika kwa makina othamanga kwambiri, kuchepetsa magwiridwe antchito a injini, ndipo kusokonezeka kwa maginito amagetsi komwe kumachitika chifukwa cha phokoso lalikulu la kugwedezeka kungachedwetse ukalamba wa dalaivala. Nkhani zomwe zili pamwambapa zimakhudza kwambiri magwiridwe antchito a makina othamanga kwambiri, ndipo kapangidwe kabwino ka ma hardware otayika pang'ono ndikofunikira kwambiri pamakina othamanga kwambiri. Mwachidule, kapangidwe ka makina othamanga kwambiri kamafunika kuganizira zinthu zambiri, kuphatikiza kulumikizana kwa mafunde amagetsi, kuchedwa kwa makina, zolakwika za magawo, ndi zovuta zaukadaulo monga kuletsa mafunde amagetsi. Ndi njira yovuta kwambiri yomwe imayika zofunikira kwambiri pa njira zowongolera, kulondola koyerekeza malo a rotor, ndi kapangidwe ka topology yamagetsi.

2, Njira Yowongolera Dongosolo Loyendetsa Magalimoto Othamanga Kwambiri

1. Kupanga Ma Model a High Speed ​​Motor Control System

Makhalidwe a ma frequency apamwamba ogwirira ntchito komanso ma frequency otsika onyamula magalimoto m'makina oyendetsa magalimoto othamanga kwambiri, komanso mphamvu ya kulumikizana kwa magalimoto ndi kuchedwa kwa makinawo, sizinganyalanyazidwe. Chifukwa chake, poganizira zinthu ziwiri zazikulu zomwe zili pamwambapa, kupanga chitsanzo ndikuwunikanso kukonzanso makina oyendetsa magalimoto othamanga kwambiri ndiye chinsinsi chopititsa patsogolo kuyendetsa bwino magalimoto a magalimoto othamanga kwambiri.

2. Ukadaulo Wowongolera Kudula Magalimoto Othamanga Kwambiri

Ukadaulo womwe umagwiritsidwa ntchito kwambiri mu makina oyendetsa magalimoto amphamvu kwambiri ndi FOC control. Poyankha vuto lalikulu lolumikizana lomwe limayambitsidwa ndi kuchuluka kwa magwiridwe antchito, njira yayikulu yofufuzira pakadali pano ndi njira zowongolera zolumikizira. Njira zowongolera zolumikizira zomwe zaphunziridwa pano zitha kugawidwa makamaka m'njira zowongolera zolumikizira zotengera chitsanzo, njira zowongolera zolumikizira zotengera kusokoneza, ndi njira zowongolera zolumikizira zotengera zovuta. Njira zowongolera zolumikizira zotengera chitsanzo zimaphatikizapo kulumikiza kwa feedforward ndi kulumikiza kwa mayankho, koma njira iyi ndi yogwirizana ndi magawo a magalimoto ndipo ingayambitse kusakhazikika kwa dongosolo pakachitika zolakwika zazikulu za parameter, ndipo sizingakwaniritse kulumikiza kwathunthu. Kusagwira ntchito bwino kwa kulumikiza kosinthasintha kumalepheretsa kugwiritsidwa ntchito kwake. Njira ziwiri zomaliza zowongolera zolumikizira pakadali pano ndi malo ofufuzira kwambiri.

3. Ukadaulo Wobwezera Kuchedwa kwa Makina Oyendetsa Mothamanga Kwambiri

Ukadaulo wowongolera kugawa zinthu m'magawo angapo ukhoza kuthetsa vuto lolumikizana la makina oyendetsa mota othamanga kwambiri, koma ulalo wochedwetsa womwe umayambitsidwa ndi kuchedwetsa ulipobe, kotero kulipira kogwira ntchito kogwira ntchito kochedwa kwa makina kumafunika. Pakadali pano, pali njira ziwiri zazikulu zolipirira kuchedwetsa kwa makina: njira zolipirira zochokera ku chitsanzo ndi njira zolipirira zodziyimira pawokha.

Gawo 03 Mapeto a Kafukufuku

Kutengera zomwe kafukufuku wapeza panopamota yothamanga kwambiriukadaulo woyendetsa magalimoto m'gulu la ophunzira, pamodzi ndi mavuto omwe alipo, njira zopangira ndi kufufuza zamagalimoto othamanga kwambiri zimaphatikizapo: 1) kafukufuku wokhudza kulosera molondola za mavuto okhudzana ndi kuchedwa kwa ma frequency apamwamba komanso kuchedwa kwa ntchito; 3) Kafukufuku wa ma algorithms owongolera magwiridwe antchito apamwamba kwambiri a magalimoto othamanga kwambiri; 4) Kafukufuku wokhudza kuyerekezera kolondola kwa malo a ngodya ndi chitsanzo cha liwiro lonse la rotor domain position estimation cha ma mota othamanga kwambiri; 5) Kafukufuku waukadaulo wolipira kwathunthu wa zolakwika mu mitundu yowerengera malo agalimoto othamanga kwambiri; 6) Kafukufuku wa High Frequency ndi Kutayika Kwambiri kwa High Speed ​​​​Motor Power Topology.
