Daidaita da yaɗuwa cikin Electrical Drives?

Takardun Electrical Drives

Electrical drives suna da shugabannin tsarin yaɗuwar motoci mai zafi, kamar haka ɗaukan yaɗuwa, kontrollofin tasiri, da kuma fuskantar yaɗuwa.

Mahimmancin Kontrollo

Kontrollon electrical drives yana da mahimmanci don bincike waɗanda suka faru daga ingancin volt ko amper.

Kontrollo na Loop Gushe-gushe

Tsarin kontrollo suna da kontrollo na loop gaba-gaba ko kontrollo na loop gushe-gushe. A kontrollo na loop gaba-gaba, mafarukar ba sa iya haɓaka masukan, wanda ya faɗa kontrollo ta gida daga mafaruka. Amma a kontrollo na loop gushe-gushe, ana yi amfani da feedback daga mafaruka don tattauna masukan. Idan mafaruka ta fi ƙarin da muhimmanci, masukan ya ƙara, kuma ya ƙara a nan lokacin da mafaruka ta fi ƙarfi. Kontrollo na loop gushe-gushe a electrical drives yana taimaka wajen bincike tsari, kawo karfi ga amsa, da kuma ƙare amsa.

• Bincike

• Kawo karfi ga amsa

• Don ƙare amsa

A wasu magabata na biyu, za a nemi cewa za a samun ɗaukar kontrollo na loop gushe-gushe da ake amfani a electrical drives, bane da ita ce DC ko AC.

Kontrollo na Muhimman Amfar

A lokacin ɗaukan yaɗuwa, motoci suna iya samun amfar mai yawa idan ba a yi ƙwarewa. Ana amfani da kontrollo na muhimman amfar don kudin wannan. Yana tattara amfan da kuma idan ya fi ƙarin da muhimmanci, feedback loop ya faru don ƙara amfan. Idan an samu da muhimmanci, feedback loop ya ƙaro, wanda ya taimaka da yaɗuwar gida.

Kontrollo na Torque na Loop Gushe-gushe

Wannan ɗaukansu na torque controller yana da shugaban da shi a jiragen da suke fitaccen battalai kamar kudan, ƙarfin lokaci, da sauransu. Mai girgizar jiragen yana haɗa accelerator don set reference torque T. An yi kontrollo akan T na gaba da accelerator.*

Kontrollo na Tasiri na Loop Gushe-gushe

Feedback loops na kontrollo na tasiri suna da amfani a electrical drives. Tun bayyana diagram yana taimaka wajen fahimtar hakan.

Za a iya tabbatar da cewa akwai labaran kontrollo, wanda za a ce kontrollo na loop gaba-gaba da kontrollo na loop gushe-gushe. Kontrollo na amfar na gaba-gaba yana ƙara amfar da torque na motor daga ƙarin da ake tabbatar. Na biyu za a nemi cewa idan reference speed Wm* ya ƙara, akwai positive error ΔWm, wanda yana nufin cewa yana buƙata ƙara tasiri.

Na biyu kontrollo na amfar yana ƙara amfar ta hanyar maximum allowable current. Idan tasiri ta samu tasiri da aka tabbatar, torque na motor yana ɗauka da load torque, akwai nasara a ƙara reference speed Wm, wanda yana nufin cewa ba a buƙace ƙara tasiri, amma yana buƙata ƙara amfar, kuma braking yana faru a maximum allowable current. Saboda haka, muna ce cewa a lokacin kontrollo na tasiri, shugaban da suka yi ƙaramin motoring zuwa braking, da kuma zuwa motoring don samun yaɗuwar gida da tasiri na motor.
