Ucwaningo ngesu lokulawula lesistimu yokusebenza ephezulu ye-CNC esekelwe ekwakhiweni okuvulekile kwe-Wang Junping, Fan Wen, Wang An, Jing Zhongliang 3 710072, 1 Xi'an: T: college, Xi'an 710032, Shanghai backbone open architecture of Haijiao Tong University, Thatha "I. izingxenye kanye nesistimu ye-CNC" njengenhlangano ephelele futhi ucabangele indlela yokuthuthukisa izinga lomsebenzi omuhle.I-Cha arr7 isu lokulawula uhlelo lwe-CNC olusebenza kahle kakhulu lwesakhiwo esivulekile a: izakhiwo ezivulekile, ukulawula ukusebenza okuphezulu kwe-CNC uhlelo 1, inombolo ecacile yokuhlukanisa isu lokulawula, idokhumenti ye-tp273, i-as s medium u level (19h ―), owesilisa (Han s >. KH, from Heyang County Wazalelwa eNtshonalanga Ithuluzi lokulawula izinombolo libheke phambili ekuthuthukisweni okuhlakaniphile, okuhlakaniphile inqwaba yobuso iwukubona ukuqapha kwenqubo yomshini wejubane nokuklama isilawuli sesevisi ye-valve esisekelayo Nokho, ukuthuthukiswa kwe-Si nokusebenzisa isidlulisi esisha, i-algorithm yokulawula i-servo ethuthukisiwe kanye nesu lokulawula inqubo kuye kwathonywa uhlelo lokulawula lwendabuko. Ngakho-ke, osolwazi abaningi bazibophezele ekusunguleni isakhiwo esisha, okungukuthi, ukwakhiwa kwezakhiwo ezivulekile. yesistimu yokulawula izinombolo engasebenzi esakhiweni esivulekile.I. Isethulo esifushane sesakhiwo sohlelo oluvulekile lokulawula uhlobo lwe-A.Uhlelo lokulawula izinombolo luyisistimu yekhompyutha yejusi ekhethekile, esetshenziselwa ukulawula insimu yezimboni, kodwa ihlukile kukhompyutha evamile.Isikhathi eside, uhlelo lwezinombolo seluthuthukile lwaba yisistimu yalo.Zisungulele esabo isakhiwo sesiqu esithambile, sebenzisa ubumfihlo bezobuchwepheshe kanye nokuvala uphawu lobuchwepheshe, ukuze kube nzima kubakhiqizi bamathuluzi omshini nabasebenzisi bokugcina ukwenza ukuthuthukiswa kwesibili, nokuthuthukisa ikhono lethuluzi lomshini nohlelo lwe-NC.Lapho ithuluzi lomshini wokufundisa nokulawula lingena endaweni yokulawula esabalalisiwe kanye nezimo eziguquguqukayo zesistimu yokukhiqiza ikholomu, futhi lidinga ngisho nokuxhumana nezinhlelo zenethiwekhi ezivamile ezifana ne-CAD / CAPP / CAM, Ezinye izisetshenziswa ze-CNC ezihloselwe imisebenzi ezimele zodwa azanele, futhi entsha izidingo zokugcwaliswa kwemvelo."Idivayisi iphinde iguqulwe ibe uhlelo oluvulekile lwe-CNC.
I-architecture evulekile i-Yi Trent yamukela i-block hierarchical junction HN futhi inikeza uxhumano lohlelo lokusebenza oluhlanganisiwe P ngokusebenzisa amafomu ahlukahlukene, aphathekayo.
I-Scalability, ukusebenzisana kanye nokulinganisa, okungukuthi, ukuvuleka kwangaphakathi kokwakheka kwesistimu nokuvuleka phakathi kwezingxenye zesistimu.2. Ngokusho kwenqubomgomo yohlelo, isu lokulawula uhlelo lwe-CNC lokusebenza kukabhasikidi elisekelwe esakhiweni esivulekile lakhiwe izingxenye ezintathu: isilawuli se-servo, i-multi-FFI detector kanye nenhlanganisela yolwazi, kanye ne-digital value processor, njengoba kuboniswe ku-KL 1, uhlelo lokucubungula lwe-Chendai. isekelwa uhlelo lwe-tantalum.Ngaphambi kokuthi izingxenye zesistimu ye-servo zidlale indima ebalulekile ekunembeni kwendawo yokusebenza, izikhungo zezimboni eziningi zifakwe amasistimu we-servo.Lezi zinhlelo ze-servo m zisebenzisa izilawuli eziphikisana nomtapo wolwazi wasekhaya 0, ezidume kakhulu ngezidingo zokwethembeka.Ukulawulwa kwesivinini sakudala njengokuhleleka komsebenzi akusatholakali - lokhu kulawulwa kokunyakaza okuqinile okusebenza kahle kubaluleke kakhulu.Inhloso yayo iwukubona ukuthi iphutha lokuhlangana kwegama liseduze neyunithi yezinhlamvu yokulungiswa kwe-fi.Ukuze uqaphele ukukhetha okugcwele kwe-europium, njengobunjiniyela, kusenezimpi eziningi zamapentshisi.I-FT iyisizathu esiyinhloko, ikakhulukazi esimweni sokungaqiniseki kwe-anti dynamic and nonlinear incertainty m, isilawuli se-servo se-a-speed high degree siklanyelwe.Lapho kusetshenziswa isilawuli se-servo somkhawulokudonsa olinganiselwe, ukubambezeleka kokuhlanganisa kwe-europium kuba imbangela eyinhloko yephutha lesikhundla, okuzothinta idigri yejometri yesiqeshana sokusebenza.Isistimu ye-flsf kufanele ibe nenduku yokulungisa i-cesium kanye nenduku yokusebenza.Lapho amapharamitha womgodi wesistimu eguqukayo, Ukusebenza kuhle kakhulu.Lawa amanetha 1 azoba namandla kakhulu ngokukhuphuka kwesivinini sokuphakela ngesikhathi sokushaywa.Lapho uklama isilawuli sokunyakaza kwenduku esebenza kahle kakhulu, lawa ma-h rubs kufanele asekelwe esinxephezelweni sokungqubuzana kwesiphakeli se-zinc esihlongozwe i-Colm ne-totnimfca.Isakhiwo sokulawula esihlanganisa umtshina ophazamisayo, i-charmer yokulawula umtapo wezincwadi wesikhundla kanye ne-fractionator, okungukuthi, isistimu engcwatshwayo esebenza kahle kakhulu (i-DOB) esekelwe kumtshina wokuphazamiseka, igeji yokuphazamiseka Isilawuli se-FFI esiphakelayo singasebenzisa isilawuli sokulinganisa esiphezulu. .Ukulandelela iphutha lesigaba esinguziro W. ukulawula okuphindaphindayo ukutsheka ukuze kuthuthukiswe ukunemba kobubanzi, nokulawula impendulo yendawo ngokuvamile kusebenzisa ukulawula kwe-PID.Ngesinxephezelo samandla okungqubuzana okungewona umugqa, izindlela ezivame ukusetshenziswa yilezi: indlela yesinxephezelo se-inthanethi esekelwe kumsebenzi ongewona umugqa womchazi, ngokusekelwe kundlela yesinxephezelo sesilawuli se-Neural esiphambene nesilawuli, ukulawulwa okuphindaphindayo okuqinile nokulawulwa kwesakhiwo esiguquguqukayo.Kodwa-ke, lapho amapharamitha wesistimu eshintsha kakhulu noma kukhona ukusheshisa okungaqhubeki ku-trajectory yokunyakaza, i-DOB ayifaneleki kakhulu.I-Yao ne-tamizuka iphakamise indlela entsha yokulawula ukunyakaza, okuyi-adaptive robust control.Isistimu ye-servo yokusebenza kukabhasikidi esekelwe ekulawuleni okuqinile okuguquguqukayo inokusebenza okuhle kokulandela umkhondo.
Ukutholwa kwezinzwa eziningi kanye nokuhlanganiswa kolwazi ekucubunguleni ukusebenza kwebhasikidi, izindlela ezivamile zokunemba kokucubungula ubhasikidi zihlanganisa ubuchwepheshe bokugwema amaphutha ngokusekelwe ekunembeni kwethuluzi lomshini webhasikidi kanye nobuchwepheshe bokunxeshezelwa kwamaphutha okusekelwe ekuqedeni iphutha ngokwalo.Inhloso yalezi zindlela ezimbili ukunciphisa iphutha lomshini wezingxenye.Leli phepha lithatha i-workpiece kanye nesistimu ye-NC njengento yonke ebumbene, ibheka indlela yokuthuthukisa ukunemba komshini wobhasikidi, futhi ixhuma ucezu lokusebenza nohlelo lwe-NC ngokusebenzisa i-Multi-sensor Detection.Uma kuqhathaniswa nesistimu yezinzwa eyodwa, uhlelo lokuhlanganisa ulwazi lwezinzwa eziningi lunobuhle bolwazi oluningi, ukubekezelela amaphutha okuhle kanye nokuthola ulwazi lwesici olungenakutholwa inzwa eyodwa.Inqubo yokwenza imishini iyinqubo eyinkimbinkimbi kakhulu futhi eguquguqukayo, futhi izinguquko zendawo, isivinini, izinga lokushisa namandla okusika kuyathintana.Kuphela ngokuqinisa ukuqoqwa, ukuhlonza nokucutshungulwa kwalolu lwazi kanye nokuthola idatha ethembekile kungalawuleka ngendlela efanele.Amasignali ahambisanayo akalwa ngezinzwa ezihlukahlukene, bese kusetshenziswa ubuchwepheshe bokuhlanganisa ulwazi lwezinzwa eziningi ukuzwa ulwazi lwesifunda sokucubungula, ukuze kuhlinzekwe isilawuli ngolwazi olubanzi lwangempela noluthembekile futhi kuthuthukiswe ukunemba kokulawula.
Ngokukhula kwesidingo sejubane nesikhathi sangempela sokucutshungulwa kolwazi lwesistimu, kanye nokuthuthukiswa kwamasekethe amakhulu ahlanganisiwe, kukhona ama-chips ahlukahlukene e-DSP anikezelwe ekucutshungulweni kwesiginali yedijithali yesikhathi sangempela Uma kuqhathaniswa nama-microprocessors enhloso ejwayelekile, izici zawo eziyinhloko. zimbili: ama-chips amaningi e-DSP athatha isakhiwo se-Harvard, okungukuthi, indawo yokugcina yemiyalelo yohlelo kanye nedatha ihlukaniswa, futhi ngayinye inekheli layo kanye nebhasi ledatha, okwenza imiyalelo yokucubungula kanye nedatha kungenziwa ngesikhathi esifanayo, okuthuthukisa kakhulu ukusebenza kahle kokucubungula;Uma i-microprocessor yenhloso evamile yenza umyalo, idinga imijikelezo yemiyalelo embalwa ukuze iqedele.I-chip ye-DSP isebenzisa ubuchwepheshe bepayipi.Nakuba isikhathi sokwenziwa komyalelo ngamunye kuseyimijikelezo yemiyalelo eminingana, ngenxa yokugeleza kweziyalezo, ezithathwe ndawonye, isikhathi sokugcina sokwenza somyalelo ngamunye siqedwa ngomjikelezo owodwa wokufundisa.
Kuhlelo lokulawula izinombolo, iphrosesa yesiginali yedijithali iqedela imisebenzi yokutholwa kwedatha, ukukhiqizwa kwe-trajectory, ukukhetha amasu okulawula nokulawula kwesikhathi sangempela.
3 isiphetho esiqala ezidingweni zomshini wokwenza ubhasikidi ngokunemba, leli phepha lithatha i-workpiece kanye nesistimu ye-NC njengenhlangano ephelele ngokusebenzisa ubuchwepheshe bokuhlanganisa ulwazi lwezinzwa eziningi, ibheka indlela yokuthuthukisa ukunemba komshini wobhasikidi, futhi ibeka phambili isu lokulawula lesistimu ye-NC Ukusebenza kwebhasikidi. ngokusekelwe esakhiweni esivulekile.Leli su libalulekile futhi ekulawuleni ezinye izidumbu ezihambayo.
