Zinthu zomwe zimathandizira kuwotcherera pano kuwongolera kulondola kwapakatikati pafupipafupi malo kuwotcherera

Mu ndondomeko yowotcherera, chifukwa kusintha kwa kukana kudzatsogolera kusintha kwa kuwotcherera panopa, kuwotcherera panopa kuyenera kusinthidwa nthawi. Pakalipano, njira zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo njira yolimbikitsira komanso njira yoyendetsera nthawi zonse, ndi zina zotero, zomwe cholinga chake ndi kusunga zitsulo zamakono nthawi zonse kudzera muzitsulo zowongolera. Chifukwa kukana kwamphamvu kumakhala kovuta kuyeza, ntchito yowongolera ndiyovuta kuigwiritsa.

Choncho, Xiaobian utenga zonse panopa kulamulira njira kukambirana, ndipo choyamba kusanthula zifukwa kutsogolera otsika kuwotcherera panopa kulondola molondola. The ulamuliro panopa wa wapakatikati pafupipafupi malo kuwotcherera makina, ntchito lamulo la thyristor conduction ngodya kulamulira kuwotcherera panopa, China amagwiritsa 50Hz alternating panopa, nthawi ndi 20ms, aliyense mkombero ali ndi theka mafunde, theka lililonse yoweyula ndi 10ms, kuti ndi, lamulo la thyristor conduction Angle akhoza kusintha aliyense 10ms. Pankhani yakuwongolera digito, nthawi yomenyedwa ndi 10ms.

10ms iyi ndiye vuto: nthawi yomenyedwa ndi yayitali kwambiri. Popeza kukana kwa chinthu chowotcherera kudzasintha ndi kuwonjezeka kwa kutentha, nthawi ya 10ms ndi yokwanira kupanga kusintha kwakukulu. The conduction Angle yowerengedwa pa nthawi yoyambira ya 10ms salinso yoyenera boma pambuyo pa kusintha kwa kukana, kotero kuwotcherera panopa ndithudi kutulutsa cholakwika chachikulu. Pambuyo pa kukhazikitsidwa kwa kutsekeka kotsekeka, ma conduction Angle ya kugunda kotsatira akhoza kusinthidwa molingana ndi kuwotcherera pakali pano kubwezedwa ndi mayankho, koma vuto lomwelo lizichitikabe pakumenya kotsatira, ndipo kutulutsa komwe kwa wowongolera kumakhala nthawi zonse. amapatuka kwambiri pamtengo womwe wapatsidwa.

Kuchokera kusanthula pamwambapa, zitha kuwoneka kuti nthawi yayitali kwambiri yomenyedwa ndiyo chifukwa chachikulu chomwe chimatsogolera ku zolakwika zazikulu zowotcherera. Mu ndondomeko yowotcherera, ngati kusintha kwa kukana kungathe kuneneratu pasadakhale, ndipo zinthu zomwe zimakhudzidwa zimaganiziridwa powerengera pa-angle, pakhoza kupezeka pakona, kotero kuti kuwotcherera panopa kuli pafupi ndi zomwe zaperekedwa. mtengo. Kutengera izi, kuwongolera kwa feedforward kumawonjezedwa pamaziko a kuwongolera kwanthawi zonse, ndipo njira yowongolera feedforward ndiyongoneneratu zakusintha komwe kumachitika chifukwa cha kukana kusintha. Choncho cholinga cha kuwongolera molondola kwa kuwotcherera panopa chimakwaniritsidwa.
