Indlela yokulawula ukushisa kwesithando somlilo sokuncibilika kwe-induction?

Ukulawula izinga lokushisa okuzenzakalelayo kwe ukuchithwa kwesithando somlilo-isho ukuvula noma ukuvala ngokuzenzakalelayo amandla omthombo wokushisa anikezwe esithandweni ngokuya ngokuchezuka kwezinga lokushisa lomlilo liye ezingeni lokushisa elinikeziwe, noma ngokuqhubekayo ukuguqula usayizi wamandla omthombo wokushisa, ukuze izinga lokushisa lomlilo lizinze futhi libe ne- izinga lokushisa elinikeziwe Ukwanelisa izidingo zenqubo yokwelapha ukushisa.

Kunezindawo ezimbili, ezintathu-isikhundla, ezilinganayo, ezilinganayo, njll., imithethonqubo evame ukusetshenziswa yokulawula okuzenzakalelayo kokushisa kokushisa.

1. Ukulungiswa kwe-Proportional (P ukulungiswa)-isignali yokuphumayo (M) yesilawuli ilingana nokokufaka kokuchezuka (e). okuyi:

M=ke

Efomini: K—–i-proportional coefficient, kunobudlelwano obulinganayo obuhambisanayo nganoma isiphi isikhathi phakathi kokufaka nokuphuma kwesilawuli esilinganiselwe, ngakho-ke lapho ukuguquka kwezinga lokushisa kwesithando somlilo kulinganisaniswa ngokulungiswa kokulinganisa, izinga lokushisa lomlilo alikwazi ukwengezwa Ekuphambukeni. ngenani elinikeziwe elibizwa ngokuthi “iphutha elimile”

2. Ukulungiswa kwe-Proportional integral (PI)–Ukuze “kumehluko omile”, engeza okubalulekile (I) ukuze ulungise okubalulekile ekulungiseni okulinganiselwe. Ukulungiswa kusho ukuthi isignali yokuphuma komlawuli kanye nokuphambuka kukhuphuka ngokuhamba kwesikhathi, kuze kube yilapho ukuphambuka kuqedwa. Asikho isignali yokuphumayo, ngakho-ke inhlanganisela yokulungiswa kokulingana nokulungiswa okuhlangene okungaqeda “umehluko omile” kubizwa ngokuthi ukulungiswa kwe-proportional integral.

3. Ukulungiswa kwezindawo ezimbili-kunezifunda ezimbili kuphela: vula noma uvale. Uma izinga lokushisa lomlilo liphansi kunenani elibekiwe, i-actuator ivuliwe ngokugcwele; lapho izinga lokushisa lomlilo lingaphezulu kwenani elibekiwe, i-actuator ivalwe ngokugcwele. (Ama-actuator ngokuvamile asebenzisa izixhumi)

4. Ukulungiswa kwezindawo ezintathu-kunamanani amabili anikeziwe omkhawulo ophezulu naphansi, lapho izinga lokushisa lomlilo liphansi kunenani elinikeziwe lomkhawulo ophansi, idivayisi yokuzijabulisa ivulwa ngokugcwele; lapho izinga lokushisa lesithando somlilo liphakathi kwenani elinikeziwe lomkhawulo ophezulu kanye nomkhawulo ophansi, i-actuator ivuliwe ingxenye; Lapho izinga lokushisa lomlilo lidlula inani eliphezulu elinikeziwe, i-actuator ivalwa ngokugcwele. (Isibonelo, uma i-heater eshubhu iyisici sokushisa, ukulungiswa kwezindawo ezintathu kungasetshenziswa ukuze kubonakale umehluko phakathi kwamandla okushisa nokubamba)
