Iyo yekudzora musimboti weiyo brushless DC mota, kuita kuti mota itenderere, chikamu chekutonga chinofanira kutanga chaona nzvimbo yemota rotor zvinoenderana nehoro-sensor, uye wozofunga kuvhura (kana kuvhara) simba riri muinverter zvinoenderana ne iyo stator mhepo.Kurongeka kwema transistors, AH, BH, CH mune inverter (aya anonzi epamusoro ruoko simba transistors) uye AL, BL, CL (aya anonzi epasi ruoko simba transistors), ita kuti ikozvino kuyerera kuburikidza nemota coil mukuteerana gadzira kumberi (kana kudzosera kumashure)) inotenderedza magineti uye inodyidzana nemagineti erotor kuitira kuti mota itendeuke newachi/kutarisana newachi.Kana iyo mota rotor ichitenderera ichienda kunzvimbo iyo horo-sensor inonzwa rimwe boka rezviratidzo, iyo control unit inotendeukira kune rinotevera boka remagetsi transistors, kuitira kuti mota inotenderera irambe ichitenderera munzira imwechete kusvika iyo control unit yasarudza kuita. dzima simba kana mota rotor ikamira.transistor (kana chete kuvhura rezasi ruoko simba transistor);kana iyo mota rotor ichizodzoserwa kumashure, iyo transistor yemagetsi inotenderera-inoteedzana inodzoserwa kumashure.Chaizvoizvo, nzira yekuvhura yemagetsi transistors inogona kuva inotevera: AH, BL boka → AH, CL boka → BH, CL boka → BH, AL boka → CH, AL boka → CH, BL boka, asi harifanire Kuvhura seAH, AL kana BH, BL kana CH, CL.Mukuwedzera, nokuti zvikamu zvemagetsi nguva dzose zvine nguva yekupindura yekuchinja, nguva yekupindura yemagetsi transistor inofanira kuverengwa kana iyo transistor yemagetsi ichidzimwa uye ichienderera.Zvikasadaro, kana ruoko rwepamusoro (kana ruoko rwezasi) rusina kuvharwa zvachose, ruoko rwezasi (kana ruoko rwepamusoro) rwatove Tundura, semhedzisiro, maoko ekumusoro neakadzika ari mapfupi-anotenderera uye iyo transistor yesimba inopiswa kunze.Kana mota ichitenderera, chikamu chekutonga chinofananidza kuraira (Command) inoumbwa nekumhanya kwakaiswa nemutyairi uye kukurumidza / kuderedzwa mwero nekumhanya kwehoro-sensor chiratidzo chekuchinja (kana kuverengerwa nesoftware), wobva wafunga boka rinotevera ( AH, BL kana AH, CL kana BH, CL kana ...) ma switch anobatidzwa, uye kuti anobatidzwa kwenguva yakareba sei.Kana kukurumidza kusina kukwana, ichava yakareba, uye kana kukurumidza kwakanyanya, inopfupiswa.Ichi chikamu chebasa chinoitwa nePWM.PWM ndiyo nzira yekuona kuti mota ichimhanya here kana kuti inononoka.Maitiro ekugadzira akadaro PWM ndiwo musimboti wekuwana yakanyatso mhanyisa kudzora.Iyo yekumhanyisa kudzora yekumhanyisa kutenderera kunofanirwa kufunga kana iyo CLOCK resolution yesystem yakakwana kubata nguva yekugadzira mirairo yesoftware.Uye zvakare, iyo nzira yekuwana data yekuchinja kwehoro-sensor siginecha inokanganisawo mashandiro eprocessor uye iko kurongeka kwekutonga.nguva chaiyo.Kana iri yakaderera-kumhanya kudzora, kunyanya yakaderera-kumhanya kutanga, shanduko yeyakadzoserwa horo-sensor chiratidzo inononoka.Maitiro ekutora chiratidzo, kugadzirisa nguva, uye kugadzirisa iyo control parameter makoshero zvinoenderana nemhando yemota yakakosha.Kana iyo yekumhanyisa kudzoka shanduko yakavakirwa pane encoder shanduko, kuitira kuti chiratidzo chechiratidzo chiwedzere kudzora zvirinani.Iyo mota inogona kumhanya zvakanaka uye kupindura zvakanaka, uye iko iko kwePID kutonga hakugone kufuratirwa.Sezvambotaurwa, iyo brushless DC mota ndeye yakavharwa-loop control, saka chiratidzo chemhinduro chakafanana nekuudza control unit kuti mota inomhanya kusvika papi kubva painomhanyisa kumhanya, iko kukanganisa (Kanganiso).Kuziva chikanganiso, zvinodikanwa kubhadharira zvakasikwa, uye nzira ine yechinyakare engineering kutonga senge PID control.Nekudaro, iyo mamiriro uye nharaunda yekutonga ndeyechokwadi yakaoma uye inoshanduka.Kana hutongi huchizove hwakasimba uye hwakasimba, zvinhu zvinofanirwa kutariswa zvinogona kusabatwa zvizere neyakajairwa engineering control, saka fuzzy control, nyanzvi system uye neural network inosanganisirwa sehungwaru Yakakosha dzidziso yekutonga kwePID.
