Idizayini eshintshile yokunqikaza yokunciphisa umsindo wemoto, idizayini yokunciphisa ukudlidliza, idizayini yokulawula ukugeleza kwetorque, ayikho inzwa yokuma, kanye nomklamo wesu lokulawula kube yizindawo zokucwaninga ze-SRM. Phakathi kwazo, idizayini yesu lokulawula elisuselwe kuthiyori yokulawula yesimanje ukucindezela umsindo, ukudlidliza kanye nesevisi ye-Torque ripple.
1. Umsindo nokudlidliza kwe-SRM cindezela umsindo nokudlidliza kwe-
switched reluctance motor, okuyibhodlela eliyinhloko elikhawulela ukuphromothwa kwe-SRM. Ngenxa yesakhiwo esine-convex ephindwe kabili, indlela yokulawula ye-asymmetric half-bridge kanye ne-non-sinusoidal air-gap magnetic field, i-SRM inomsindo wemvelo, Ukudlidliza kukhulu kunamamotho asynchronous kanye namamotho kazibuthe angapheli, futhi lapho. yizingxenye eziningi zefrikhwensi ephezulu, umsindo ubukhali futhi uhlaba, futhi amandla okungena anamandla. Imibono yocwaningo yokunciphisa umsindo nokunciphisa ukudlidliza ngokuvamile ihlukaniswe izinkomba eziningana:
1) Ukuhlaziywa kwe-modal, funda umthelela wohlaka, i-stator kanye ne-rotor shape, ikhava yokugcina, njll. kumodi yoku-oda ngayinye, hlaziya imvamisa yemvelo ngaphansi kwemodi yokuhleleka ngakunye, Phenya ukuthi imvamisa ye-electromagnetic excitation ikude kanjani nemvamisa yemvelo imoto.
2) Nciphisa umsindo nokudlidliza ngokushintsha ukuma kwe-stator ne-rotor, njengokushintsha i-ji arc, umumo, ukujiya kwejoka, i-slotting yesikhundla esiyinhloko, i-oblique groove, ukubhoboza, njll.
3) Ziningi izakhi zezimoto eziqanjiwe, kodwa zonke zinezinkinga. Kuphakathi kokuthi ukukhiqiza kunzima, izindleko ziphezulu, noma ukulahlekelwa kukhulu. Ngaphandle kokukhetha, zonke ziyimikhiqizo yaselabhorethri nezinto ezalelwe ithesis.
2. Ukulawulwa kwe-torque pulsation yenjini eshintshayo yokungafuni
ngokuyisisekelo iqala ngokulawula. Isiqondiso esijwayelekile ukulawula i-torque esheshayo noma ukuthuthukisa i-torque emaphakathi. Kukhona i-closed-loop control kanye ne-open-loop control. Ukulawulwa kwe-loop evaliwe kudinga impendulo ye-torque noma nge-current, Okuguquguqukayo okufana ne-voltage ibala i-torque ngokungaqondile, nokulawula iluphu evulekile ngokuyisisekelo kuwukubheka ithebula.
3. Ucwaningo ngenzwa yokuma yemoto eshintshashintshayo yokungabaza
Isiqondiso esingenayo inzwa yesikhundla singumkhiqizi omkhulu wamaphepha. Ngokombono, kunezindlela zokujova i-harmonic, izindlela zokubikezela i-inductance, njll. Ngeshwa, azikho izinzwa zesikhundla emikhiqizweni yezimboni ezivuthiwe ekhaya nakwamanye amazwe. Kungani? Ngicabanga ukuthi kusengenxa yokungathembeki. Ezinhlelweni zezimboni, ulwazi lwendawo olungathembekile lungabangela izingozi nokulahlekelwa, okungabekezeleleki emabhizinisini nakubasebenzisi. Izindlela zamanje zokuthola indawo ezithembekile ze-SRM zifaka izinzwa zokuma ezinokulungiswa okuphansi ezimelelwa amaswishi e-photoelectric namaswishi eHholo, ahlangabezana nezidingo zokushintsha zamamotho ezikhathini ezijwayelekile, kanye nezinzwa zokuma ezinemba okuphezulu ezimelelwa izishumeki nezixazululi zezithombe. Hlangana nesidingo sokulawula okunembe kakhudlwana.
Okungenhla okuqukethwe okuyinhloko kwe-switched reluctance motor. Phakathi kwazo, isixazululi sohlobo oluhlukene sifaneleka kakhulu ukusetshenziswa kwe-SRM, enosayizi omncane, ukunemba okuphezulu kanye nokuvumelana nezimo okuhle kwemvelo. Ngicabanga ukuthi inketho engenakugwenywa ye-servo SRM esikhathini esizayo.
