Enkambweni yokushisela, ngenxa yokuthi ukuguqulwa kokumelana kuzoholela ekushintsheni kwe-welding yamanje, i-welding current idinga ukulungiswa ngesikhathi. Njengamanje, izindlela ezivame ukusetshenziswa zifaka indlela yokumelana okuguquguqukayo kanye nendlela yokulawula yamanje njalo, njll., inhloso yayo iwukugcina i-welding yamanje ngokuqhubekayo ngokusebenzisa izinyathelo zokulawula. Ngenxa yokuthi ukumelana okuguquguqukayo kunzima ukukukala, ukusebenza kokulawula kunzima ukukusebenzisa.
Ngakho-ke, i-Xiaobian isebenzisa indlela yokulawula yamanje eqhubekayo ukuze ixoxe, futhi iqale ihlaziye izizathu eziholela ekunembeni okuphansi kokulawula ukushisela. Ukulawulwa kwamanje komshini wokushisela we-intermediate frequency spot welding, kusetshenziswa ukulawulwa kwe-thyristor conduction Angle ukulawula i-welding current, i-China isebenzisa i-50Hz alternating current, isikhathi singama-20ms, umjikelezo ngamunye unamagagasi amabili, isigamu ngasinye singu-10ms, lokho ukuthi, ukulawulwa kwe-Angle conduction thyristor kungalungiswa kuphela njalo ngo-10ms. Mayelana nokulawulwa kwedijithali, isikhathi sokushaywa ngu-10ms.
Lokhu 10ms inkinga: isikhathi sokushaya side kakhulu. Njengoba ukumelana kwento ezoshiselwa kuzoshintsha ngokwanda kwezinga lokushisa, isikhathi esingu-10ms sanele ukukhiqiza inani elikhulu loshintsho. I-Angle conduction ibalwa ngesikhathi sokuqala se-10ms ayisafanele isimo ngemuva kokushintsha kokumelana, ngakho-ke i-welding current izokhiqiza iphutha elikhulu. Ngemuva kokwamukelwa kokulawulwa kwe-loop evaliwe, i-Angle conduction yesigqi esilandelayo ingalungiswa ngokuya nge-welding current ebuyiswa yimpendulo, kodwa inkinga efanayo isazokwenzeka ekubetheni okulandelayo, futhi ukuphuma kwamandla kwesilawuli kuzohlala njalo. yehla kakhulu kunani elinikeziwe.
Kusukela ekuhlaziyweni okungenhla, kungabonakala ukuthi isikhathi eside kakhulu sokushaya yisona sizathu esiholela ephutheni elikhulu lamanje lokushisela. Enqubweni yokushisela, uma ukuguqulwa kokumelana kungabikezelwa kusengaphambili, futhi izici ezithonya zicatshangelwa lapho kubalwa i-angle-angle, i-angle enengqondo enengqondo ingatholakala, ukuze i-welding current isondele kuleyo enikeziwe. inani. Ngokusekelwe kulokhu, ukulawulwa kwe-feedforward kunezelwa ngesisekelo sokulawula okujwayelekile, futhi i-algorithm yokulawula i-feedforward ngokuyinhloko iwukubikezela ushintsho lwamanje olubangelwa ukushintsha kokumelana. Ngakho-ke inhloso yokulawula okunembile kwe-welding current iyafezeka.
