DSP brushless dc motor katoa pūnaha mana mamati

1 te hangahanga taputapu hoahoa poraka hoahoa

te wharite o te nekehanga o te motini dc: he rite te whakatere ki te taipana o te motini, me te taipana he rite ki te motini o naianei, no reira, ki te whakatutuki i te tika teitei, teitei te mahi hihiri o te mana motuka, me hiahia koe ki te tere o te motuka i te wa ano, o naianei me te waahi mo te whakamatautau me te whakahaere. Ko te ahua 1 he hoahoa poraka punaha whakahaere motika dc brushless, kua whakaritea te punaha i roto i te kaiwhakahaere tere me te kaiwhakahaere o naianei, me te whakatika i te tere me te naianei o te motuka, i waenga i te hononga cascade, te whakaputanga tere tere hei whakaurunga kaiwhakahaere o naianei, ka whakamahi i te putanga o te kaiwhakahaere o naianei hei whakahaere i te waahanga PWM.

rite whakaaturia i roto i te ahua 1, ka taea te wehea te wae whakahaere pūnaha ki e rua nga wahi: te mahi o te anga raina iraira titoa o TMS320LF2407A DSP whakatinanatanga pūnaha iti, ngā ia DSP me te rokiroki waho, etahi atu mo te tohu urupare wahi riro. Ko te tohu urupare o naianei kua inehia e te huānga o te whare, na roto i te A/D module F2407 ki te rahinga matihiko, ka whakamahia te tohu tuunga rotor ki te whakaputa i te commutator rotor tika, te kitenga encoder photoelectric me te whakahoki whakahoki mai ki te ahunga hurihuri motuka me te punaha Angle DSP, te hanga i te mana kopae kati. Te tuunga o te punaha na te miihini o runga. E toru-waahanga ac whakauru i muri i te whakatikatika, ngaohiko ngaohiko ki te whakarato i te mana dc mo te hiko hurihuri, te hikohiko hiko o te tohu whakaoho e whakaratohia ana e te miihini o runga, ko te kaupapa ko te whakaputanga o te tauwehenga mahi whakarite o te tohu PWM, ma te whakatika i te whanui o te tohu PWM ki te whakahaere i te waa me te wa o te ngongo hiko, kia mohio ai te mana o te motuka korepu. Rautaki whakahaere o

tenei punaha na roto i te toru kati kati (Ko te kopae tuunga, ko te kapiti tere me te kohanga o naianei)Hanga ki te mohio ki te mana whakahaere o te miihini. Ka rite ki whakaaturia i roto i te ahua 2.

ka rere te motopaika, te tūnga o te inenga tohu homai i muri i (Ua me te tohu tūnga urupare o te UbPosition koropiko)PID te whakarite tere tohutoro Vg, pūmana urupare rite ki te ine korero tūnga ki te tātai i te tere o nāianei & omega; S, motopaika kore, Vg me & omega; S PI tatauhia i roto i te DSP (Speed loop)Tikina te naianei mo te Uig tohutoro ngaohiko kua homai, te motuka awhiowhio te tohu urupare o naianei i muri i te kitenga o te pukoro o naianei mai i te A/D ki te DSP, ma te huri mai i te huringa tuatahi o naianei ngaohiko urupare o naianei Uif me te Uig Uif PI tataunga, tikina te putanga o te kaiwhakahaere o naianei ki te whakatika i te tauwehenga mahi, me te whakahaere i te whakahaerenga, ka kati i te tuunga o te hiko o naianei, ka kati i te hiko o naianei, ka kati i te tuunga o naianei. mana taipana.

i roto i nga punaha whakahaere e toru katia, ko te porowhita o naianei me te kowiri tere ko te mowhiti o roto, ko te tuunga o waho. Ko te huringa o naianei ko te whakapai ake i te tere o te punaha, me te paanga o te aukati pokanoa o roto o naianei, whakawhāiti i te tino taurangi o naianei mo te mahi haumaru o te punaha, te whakahaere PI o naianei. Ko te painga o te huringa tere ko te whakanui ake i te kaha o te punaha ki te aukati i te whakararuraru o te kawenga me te aukati i te rerekee o te tere, te huringa tere PI regulator. Ko te mahi a te kopae tuunga ko te whakarite i te tino tika me te mahi aroturuki hihiri o te punaha. Ko te waahi ka mau te mana PID wehenga, ara, i te timatanga o te ara i whakapaehia he nui ki te whakakore i te mahi whakauru, kia tere te tere o te huringa o te ine, ina he tata te utu ki te uara hou te taapiri i te mahi whakauru. Ka taea e tenei te karo ki te overshoot ka taea te whakapoto i te wa o te noho pumau, ka whai hua o te whakatikatika whakauru. Whakaatu 3 mo te pihi whakautu taahiraa me te momo taahiraa hua whai waahi.
