High speed motorsvari kutambira kutariswa kuri kuwedzera nekuda kwekunakirwa kwavo kuri pachena senge yakakwira simba density, saizi diki uye huremu, uye kushanda kwakanyanya. Iyo inoshanda uye yakagadzikana dhiraivha system ndiyo kiyi yekushandisa zvizere kuita kwakanakisa kwemota dzinomhanya kwazvo. Chinyorwa ichi chinonyanyo ongorora matambudziko ehigh-speed motordhiraivha tekinoroji kubva kuzvinhu zvekutonga zano, fungidziro yekona, uye simba topology dhizaini, uye inopfupisa zvazvino tsvakiridzo mhedzisiro kumba nekune dzimwe nyika. Mushure mezvo, inopfupikisa uye inotarisira maitiro ekuvandudza kwehigh-speed motordhiraivha tekinoroji.
Chikamu 02 Tsvakurudzo Yemukati
High speed motorsvane zvakawanda zvakanaka zvakadai sesimba guru remagetsi, vhoriyamu diki uye uremu, uye kushanda kwakanyanya. Iwo anoshandiswa zvakanyanya muminda senge aerospace, dziviriro yenyika uye chengetedzo, kugadzirwa uye hupenyu hwezuva nezuva, uye zvakakosha kutsvagisa zvemukati uye kutungamira kutungamira nhasi. Mune yakakwirira-kumhanya-kuremerwa maapplication akadai semagetsi spindles, turbomachinery, micro gasi turbines, uye flywheel chengetedzo yesimba, kushandiswa kwemamotors anomhanya-mhanya kunogona kuwana yakananga dhiraivha chimiro, kubvisa zvinosiyana zvekumhanya zvishandiso, kuderedza zvakanyanya vhoriyamu, huremu, uye mari yekugadzirisa. , nepo zvichivandudza kuvimbika, uye ine tarisiro yakafara kwazvo yekushandisa.High speed motorskazhinji inoreva kumhanya kunodarika 10kr/min kana kuomerwa kukosha (chigadzirwa chekumhanya uye square midzi yesimba) inodarika 1 × Iyo mota ye105 inoratidzwa muMufananidzo 1, iyo inofananidza data rakakodzera reimwe inomiririra prototypes yeakakwira-speed motors zviri zviviri mudzimba. uye pasi rose. Mutsara wakadhindwa muMufananidzo 1 ndeye 1 × 105 kuoma kwemazinga, nezvimwe
1,Zvakaoma muHigh Speed Motor Drive Technology
1. System kugadzikana nyaya panguva yakakwirira fundamental frequencies
Kana iyo mota iri mune yakakwira yekushanda yakakosha frequency state, nekuda kwekugumira senge analog-to-digital yekushandura nguva, digital controller algorithm execution nguva, uye inverter switching frequency, iyo inotakura frequency yeyakakwira-kumhanya mota drive system yakadzikira. , zvichiita kuti kuderera kukuru kwekushanda kwemotokari.
2. Dambudziko repamusoro-chaiyo rotor chinzvimbo chekufungidzira mune yakakosha frequency
Munguva yekushanda kwekumhanya-mhanya, iko kurongeka kwenzvimbo yerotor kwakakosha pakuita kwekushanda kwemota. Nekuda kwekuvimbika kwakadzika, hukuru hukuru, uye kudhura kwakakwira kwema mechanical position sensors, sensorless algorithms inowanzoshandiswa mune yakakwirira-kumhanya kudzora masystem. Nekudaro, pasi pepamusoro pekushanda kwakakosha frequency mamiriro, kushandiswa kwenzvimbo sensorless algorithms inotarirwa kune zvisina kunaka zvinhu senge inverter nonlinearity, spatial harmonics, loop mafirita, uye inductance parameter kutsauka, zvichikonzera kukanganisa kwakakosha kweyerotor chinzvimbo.
3. Ripple kudzvinyirira mu-high-speed motor drive systems
Iyo diki inductance yeakakwira-kumhanya motors zvinotungamira kune dambudziko rehombe razvino ripple. Iyo yakawedzera kurasikirwa nemhangura, kurasikirwa kwesimbi, torque ripple, uye ruzha rwekuzunguzika kunokonzerwa neakakwira ikozvino ripple inogona kuwedzera zvakanyanya kurasikirwa kweyakakwira-kumhanya masisitimu emota, kuderedza kuita kwemota, uye kukanganiswa kwemagetsi kunokonzerwa neruzha rwekuzunguza kwakanyanya kunogona kukurumidza kuchembera. mutyairi. Idzi nyaya dziri pamusoro dzinokanganisa zvakanyanya kuita kweyepamusoro-kumhanya mota dhiraivha masisitimu, uye iyo optimization dhizaini yeyakaderera kurasikirwa Hardware maseketi kwakakosha kune yakakwirira-kumhanya mota dhiraivha masisitimu. Muchidimbu, dhizaini yeakakwira-kumhanya mota dhiraivha system inoda kutariswa kwakadzama kwezvinhu zvakawanda, zvinosanganisira ikozvino loop coupling, kunonoka kwehurongwa, kukanganisa kweparameta, uye matambudziko ehunyanzvi akadai sekudzvanya kwazvino. Icho chiitiko chakaomarara kwazvo chinoisa zvakakwirira zvinodikanwa pamaitiro ekudzora, rotor chinzvimbo chekufungidzira kurongeka, uye simba topology dhizaini.
2, Kudzora Strategy yeHigh Speed Motor Drive System
1. Modelling yeHigh Speed Motor Control System
Hunhu hwepamusoro hwekushanda hwakakosha frequency uye yakaderera mutakuri frequency reshiyo mune yakakwira-kumhanya mota dhiraivha masisitimu, pamwe nepesvedzero yekubatanidza mota uye kunonoka pane sisitimu, haigone kufuratirwa. Naizvozvo, tichifunga nezvezvinhu zviviri zviri pamusoro apa, kuenzanisira uye kuongorora kuvakwazve kweakakwira-kumhanya madhiraivha masisitimu ndiyo kiyi yekuwedzera kuvandudza kutyaira kwemamotor anomhanya.
2. Decoupling Control Technology yeHigh Speed Motors
Iyo inonyanya kushandiswa tekinoroji mune yakakwirira-inoshanda mota dhiraivha masisitimu ndeyeFOC kutonga. Mukupindura dambudziko rakakomba rekubatanidza rinokonzerwa neakanyanya kushanda akakosha frequency, iyo huru yekutsvagisa nzira parizvino ndeyekubvisa kudzora maitiro. Mazano ekudzora ekugadzirisa pari zvino akadzidzwa anogona kunyanya kukamurwa kuva modhi-based decoupling control strategy, kuvhiringidza muripo wakavakirwa pakuita decoupling control strategy, uye yakaoma vector regulator based decoupling control strategy. Model based decoupling control maitiro anonyanya kusanganisira feedforward decoupling uye mhinduro yekubvisa, asi zano iri rinonzwa kune mota paramita uye rinogona kutotungamira mukusagadzikana kwehurongwa muzviitiko zvezvikanganiso zvakakura zveparameter, uye haigone kuzadzisa decoupling. Iyo yakashata dynamic decoupling performance inoganhura iyo application range. Iwo ekupedzisira maviri ekupedzisira ekugadzirisa maitiro ekudzora ari parizvino ekutsvagisa hotspots.
3. Kunonoka Kubhadhara Technology kune High Speed Motor Systems
Decoupling control tekinoroji inogona kunyatso kugadzirisa dambudziko rekubatanidza yeakakwira-kumhanya mota dhiraivha masisitimu, asi yekunonoka link yakaunzwa nekunonoka ichiripo, saka inoshanda inoshanda muripo wekunonoka system inodiwa. Parizvino, pane nzira mbiri dzinoshanda dzekuripira kunonoka kwehurongwa: marongero anoenderana nemaitiro emuripo uye maitiro akazvimirira emuripo.
Chikamu 03 Tsvakurudzo Mhedziso
Zvichienderana nezvinoitwa patsvagiridzo yazvino muhigh-speed motordhiraivha tekinoroji munharaunda yezvidzidzo, yakasanganiswa nezvinetso zviripo, kusimudzira uye kutsvagisa nzira dzemamotor anomhanya zvakanyanya anosanganisira: 1) tsvakiridzo pamusoro pekufanotaura chaiko kweyakanyanya kukosha frequency ikozvino uye inoshanda muripo kunonoka zvine chekuita nenyaya; 3) Tsvagiridzo pane yakakwira dynamic performance control algorithms yeakakwira-kumhanya mota; 4) Tsvagiridzo pamusoro peyechokwadi fungidziro yekona chinzvimbo uye yakazara yekumhanyisa domain rotor chinzvimbo chekufungidzira modhi yeakanyanya kumhanya mota; 5) Tsvagiridzo pahunyanzvi hwekubhadhara tekinoroji yezvikanganiso mune yakakwirira-kumhanya mota chinzvimbo estimation modhi; 6) Tsvagiridzo yePamusoro Frequency uye Kurasika Kwepamusoro kweHigh Speed Motor Power Topology.
