Ngaphansi kwemvelo yokushisa ephezulu nephansi, izici zedivayisi nezinkomba zesistimu yemoto kazibuthe unomphela kushintsha kakhulu, imodeli yemoto namapharamitha kuyinkimbinkimbi, ukungafani kwe-nonlinearity kanye ne-coupling degree kuyakhuphuka, nokulahlekelwa kwedivayisi yamandla kushintsha kakhulu.Akukhona nje kuphela ukuhlaziywa kokulahlekelwa komshayeli kanye necebo lokulawula ukukhuphuka kwezinga lokushisa okuyinkimbinkimbi, kodwa futhi ukulawula ukusebenza kwe-Four-quadrant kubaluleke kakhulu, futhi umklamo ovamile wesilawuli sedrayivu kanye nesu lokulawula isistimu yemoto ayikwazi ukuhlangabezana nezidingo zendawo yokushisa ephezulu.
Isilawuli sedrayivu esiklanywe ngokujwayelekile sisebenza ngaphansi kwezinga lokushisa le-ambient elizinzile, futhi asivamile ukucabangela izinkomba ezifana nesisindo nevolumu.Kodwa-ke, ngaphansi kwezimo ezinzima zokusebenza, izinga lokushisa le-ambient liyahlukahluka ebangeni lokushisa elibanzi -70 kuya ku-180 ° C, futhi amadivayisi amaningi kagesi awakwazi ukuqaliswa kulokhu kushisa okuphansi, okuholela ekuhlulekeni komsebenzi womshayeli.Ukwengeza, kukhawulelwe ngenani eliphelele lesistimu yemoto, ukusebenza kokukhipha ukushisa kwesilawuli sedrayivu kufanele kuncishiswe kakhulu, okubuye kuthinte ukusebenza nokuthembeka kwesilawuli sedrayivu.
Ngaphansi kwezimo zokushisa eziphakeme kakhulu, i-SPWM evuthiwe, i-SVPWM, izindlela zokulawula i-vector nokunye ukulahlekelwa kokushintsha kukhulu, futhi izicelo zabo zilinganiselwe.Ngokuthuthuka kwethiyori yokulawula kanye nobuchwepheshe bokulawulwa kwedijithali, ama-algorithms athuthukile ahlukahlukene afana ne-speed feedforward, ubuhlakani bokwenziwa, isilawuli esifiphele, inethiwekhi ye-neuron, ukulawulwa kwesakhiwo esishintshashintshayo semodi eslayidayo kanye nokulawulwa kwesiphithiphithi konke kuyatholakala ekulawuleni kwesimanje okuhlala unomphela kukazibuthe motor servo.isicelo esiyimpumelelo.
Ohlelweni lokulawula ukushayela lwemoto kazibuthe unomphela endaweni yokushisa okuphezulu, kuyadingeka ukusungula imodeli ehlanganisiwe ye-motor-converter esekelwe ekubalweni kwensimu ebonakalayo, ukuhlanganisa eduze izici zezinto zokwakha namadivayisi, futhi wenze ukuhlaziya kokuxhumanisa kwe-field-circuit ukuze ngokugcwele. cabanga ngomthelela wemvelo kumotho.Umthelela wezimpawu zesistimu kanye nokusetshenziswa okugcwele kobuchwepheshe bokulawula besimanje kanye nobuchwepheshe bokulawula obuhlakaniphile kungathuthukisa ikhwalithi yokulawula ebanzi yemoto.Ngaphezu kwalokho, amamotho kazibuthe ahlala unomphela asebenza ezindaweni ezinokhahlo akulula ukushintshwa, futhi angaphansi kwezimo zokusebenza zesikhathi eside, kanye nemingcele yangaphandle yemvelo (okuhlanganisa: izinga lokushisa, ingcindezi, isivinini sokugeleza komoya kanye nokuqondisa, njll.) ashintsha ngokuyinkimbinkimbi, okuholela enjini. ukulandelela izimo zokusebenza zesistimu.Ngakho-ke, kuyadingeka ukutadisha ubuchwepheshe bokuklama kwesilawuli se-high robustness drive semoto kazibuthe unomphela ngaphansi kwesimo sokuphazamiseka kwepharamitha nokuphazamiseka kwangaphandle.
