Kachiwiri, chiwembu chowongolera magalimoto chimagwiritsidwa ntchito kuwongolera injini, koma ndi injini yanji?Kodi ndi mota ya DC kapena ya AC? Nanga bwanji kuchuluka kwa mphamvu?Zonsezi ziyenera kufufuzidwa pamene mtundu wa galimoto watsimikiziridwa! Kenako, ingoyang'anani mitundu ya injini:
Kuchokera pamalingaliro amtundu wamagetsi, imatha kugawidwa m'magulu omwe ali pamwambapa, zomwe zimatsogolera kukupanga njira zosiyanasiyana zowongolera magalimoto; Kugawa kwina kutulutsa mitundu yosiyanasiyana.
Mwachitsanzo, ma mota a DC amathanso kugawidwa kukhala ma motors agawo limodzi ndi ma motors atatu;ndipo chifukwa cha njira zowongolera zofananira zamagulu awa, zitha kugawidwa mu algorithm yotsatirayi.Onani!
Kenako, imathanso kugawidwa malinga ndi mphamvu: Tanthauzo lagalimoto molingana ndi magulu osiyanasiyana amagetsi! Chifukwa chake, yankho la kuwongolera magalimoto liyenera kusiyanitsidwa molingana ndi kugwiritsa ntchito ndi mtundu wagalimoto!Izo sizingakhoze generalized!Servo Motors, makokedwe Motors, anazimitsa kunyinyirika Motors, ndi okhazikika maginito synchronous Motors onse amasiyanitsidwa malinga ndi ntchito yawo.Pa ulamuliro wa galimoto, palinso magawano mapulogalamu ndi hardware.Nayi kuyang'ana pamlingo wowongolera mapulogalamu:Ma aligorivimu omwe amagwiritsidwa ntchito kwambiri, ndiye kuti, omwe amagwiritsidwa ntchito mwanjira yodziwika bwino ndi: DC mota: Zimatengera ngati ndi gawo limodzi kapena gawo limodzi! : Ndiosavuta kuwongolera, yolunjika kwambiri ndikuwongolera voteji, zowona, kuwongolera liwiro kumathekanso;Ndipo magawo atatu: njira zowongolera zosiyanasiyana zingagwiritsidwe ntchito, monga kuwongolera kwamagetsi mwachindunji, kuwongolera kwa pwm kapena njira yowongolera magawo asanu ndi limodzi, yomwe imatha kumalizidwa ndi ma microcomputer ambiri a single-chip, trapezoidal wave control kapena sine wave control, zomwe zili zolondola. chip chimayika patsogolo zina zofunika, monga ngati mphamvuyo ndi yokwanira, inde, imathanso kukhala ndi FOC control, etc.;
Kenako ma mota a AC amathanso kugawidwa m'magulu.Mulingo wa aligorivimu umatengera kuwongolera kwa pid kwanthawi yayitali, inde, palinso zowongolera zamtundu wa neural network, kuwongolera kosamveka, kuwongolera kosinthika, ndi zina zambiri; Kenako bwererani ku funso, chip chomwe chili chabwinoko ndi chiti? Malinga ndi zomwe zili pamwambapa, zitha kuwoneka. kuti pali mitundu yambiri ya ma motors, ndipo payenera kukhala tchipisi tosiyanasiyana kuti tikwaniritse zofunikira pamitundu yosiyanasiyana ndi ma aligovimu osiyanasiyana!Kugwiritsa ntchito fanizo, kuwongolera kosavuta kwa magawo asanu ndi limodzi kumatha kuzindikirika ndi kompyuta wamba 51 single-chip, koma pomwe zinthu zathu ziyenera kugwiritsidwa ntchito?Ngati ndi malonda ogula, ndi okwanira kuti agwiritsidwe ntchito, ndiye 51 akhoza kukwaniritsa zofunikira, ndipo ngati amagwiritsidwa ntchito m'makampani, ndikwanira kusintha kukhala ARM, ndipo ngati agwiritsidwa ntchito m'galimoto, ndiye mitundu iwiriyi si yovomerezeka.Chomwe chiyenera kugwiritsidwa ntchito ndi MCU yomwe ingathe kukumana ndi msinkhu wa galimoto! Choncho, mfundo yosankha chip kwa kayendetsedwe ka galimoto ndikuti popeza zimatengera mtundu wa galimoto, zimatengeranso ntchito! komanso zina zofanana.Mwachitsanzo, chifukwa ndikuwongolera magalimoto, njira yanthawi zonse yam'mbuyomu nthawi zambiri imayenera kusonkhanitsa zidziwitso zaposachedwa, kotero amplifier angagwiritsidwe ntchito kutembenuza zomwe zilipo ndikuzitumiza ku MCU kuti zisinthidwe;kumene, ndi chitukuko cha madera Integrated, The chisanadze dalaivala gawo ntchito m'mbuyomu tsopano akhoza mwachindunji Integrated mu MCU ndi ena opanga, kupulumutsa masanjidwe danga! voteji, pwm control imafuna mcu kusonkhanitsa, can/LIN ndi zowongolera zina zomwe zimagwiritsidwa ntchito pamagalimoto zimafunikira tchipisi todzipatulira kuti tisamutse ndikutumiza ku mcu, ndi zina zambiri;
Apa, chip chimodzi sichivomerezedwa, koma opanga ambiri padziko lapansi akugwiritsa ntchito njira zosiyanasiyana zamagalimoto.Kuti mumve zambiri, chonde pitani patsamba loyambira! Opanga oyambira: infineon, ST, microchip, freescale, NXP, ti, onsemiconductor, ndi zina zambiri, akhazikitsa njira zosiyanasiyana zowongolera magalimoto.
