Umgomo wokulawula we-brushless DC motor, ukwenza i-motor ijikeleze, ingxenye yokulawula kufanele iqale inqume indawo ye-motor rotor ngokusho kwe-hall-sensor, bese inquma ukuvula (noma ukuvala) amandla ku-inverter ngokusho i-stator winding. Ukuhleleka kwama-transistors, AH, BH, CH ku-inverter (lokhu kubizwa ngokuthi ama-transistors wamandla engalo engenhla) kanye ne-AL, BL, CL (lezi zibizwa ngokuthi ama-transistors amandla engalo ephansi), yenza ukugeleza kwamanje kukhoyili yemoto ngokulandelana khiqiza phambili (noma uhlehla) ) izungezisa inkambu kazibuthe futhi ixhumane nozibuthe berotha ukuze injini ijike ngokwewashi/ngokuphambene newashi. Lapho i-rotor ye-motor ijikeleza endaweni lapho inzwa yehholo izwa elinye iqembu lamasignali, iyunithi yokulawula ivula iqembu elilandelayo lama-transistors amandla, ukuze injini ejikelezayo iqhubeke nokuzungeza ohlangothini olufanayo kuze kube yilapho iyunithi yokulawula inquma cisha amandla uma i-motor rotor ima. i-transistor (noma uvule kuphela i-transistor yamandla engalo ephansi); uma i-rotor ye-motor izohlehliswa, ukulandelana kwe-transistor yokuvula amandla kuyahlehliswa. Ngokuyisisekelo, indlela yokuvula yama-transistors amandla ingaba kanje: AH, BL iqembu → AH, CL iqembu → BH, CL iqembu → BH, AL iqembu → CH, AL iqembu → CH, BL iqembu, kodwa akumele Vula njengo-AH, AL noma BH, BL noma CH, CL. Ngaphezu kwalokho, ngenxa yokuthi izingxenye ze-elekthronikhi zihlala zinesikhathi sokuphendula sokushintsha, isikhathi sokuphendula se-transistor yamandla kufanele sinakwe lapho i-transistor yamandla icishiwe futhi ivuliwe. Uma kungenjalo, lapho ingalo engaphezulu (noma ingalo ephansi) ingavalwa ngokuphelele, ingalo engezansi (noma ingalo engaphezulu) isivele Vula, ngenxa yalokho, izingalo ezingenhla nezingaphansi zifushane futhi i-transistor yamandla iyashiswa. Lapho injini iphenduka, ingxenye yokulawula izoqhathanisa umyalo (Umyalo) owakhiwe isivinini esibekwe umshayeli kanye nezinga lokusheshisa/lokwehla ngesivinini sokushintsha kwesignali yenzwa yehholo (noma ebalwa ngesofthiwe), bese inquma iqembu elilandelayo ( AH, BL noma AH, CL noma BH, CL noma …) amaswishi avuliwe, nokuthi akhanya isikhathi esingakanani. Uma ijubane linganele, lizoba lide, futhi uma ijubane liphezulu kakhulu, lizofinyezwa. Le ngxenye yomsebenzi wenziwa ngabakwaPWM. I-PWM iyindlela yokunquma ukuthi ijubane lemoto liyashesha noma lihamba kancane. Indlela yokwenza i-PWM enjalo iwumgogodla wokufinyelela ukulawula isivinini okunembe kakhudlwana. Ukulawulwa kwesivinini kwesivinini esikhulu sokuzungezisa kufanele kucabangele ukuthi ukulungiswa kweWASHI lesistimu kwanele yini ukubamba isikhathi sokucubungula imiyalelo yesofthiwe. Ngaphezu kwalokho, indlela yokufinyelela idatha yokuguqulwa kwesiginali yenzwa yehholo iphinde ithinte ukusebenza kwephrosesa kanye nokulunga kokwahlulela. isikhathi sangempela. Ngokuqondene nokulawula isivinini esiphansi, ikakhulukazi ukuqalisa ngesivinini esiphansi, ukuguqulwa kwesiginali yenzwa yehholo ebuyisiwe kuba kancane. Indlela yokuthwebula isiginali, ukucubungula isikhathi, nokumisa amanani epharamitha yokulawula ngokufanele ngokuya nezici zemoto kubaluleke kakhulu. Noma ukuguqulwa kokubuyisela isivinini kusekelwe ekushintsheni kwesifaki khodi, ukuze ukulungiswa kwesignali kunyuswe ukuze kulawulwe kangcono. I-motor ingasebenza kahle futhi iphendule kahle, futhi ukufaneleka kokulawula kwe-PID akunakunakwa. Njengoba kushiwo ngaphambili, i-brushless DC motor iyisilawuli se-loop evaliwe, ngakho-ke isignali yempendulo ilingana nokutshela iyunithi yokulawula ukuthi ijubane lemoto likude kangakanani nejubane eliqondiwe, okuyiphutha (Iphutha). Ukwazi iphutha, kuyadingeka ukunxephezela ngokwemvelo, futhi indlela inokulawulwa kobunjiniyela bendabuko njengokulawula kwe-PID. Nokho, isimo kanye nendawo yokulawula empeleni kuyinkimbinkimbi futhi kuyashintsha. Uma ukulawula kufanele kuqine futhi kuhlale isikhathi eside, izici okufanele zicatshangelwe zingase zingaqondwa ngokugcwele ukulawula kobunjiniyela bendabuko, ngakho ukulawula okungaqondakali, uhlelo lochwepheshe kanye nenethiwekhi ye-neural nakho kuzofakwa njengethiyori ehlakaniphile yokulawula i-PID.
