Ucwaningo ngesu lokulawula uhlelo lwe-CNC olusebenza kahle olusekelwe ekwakhiweni okuvulekile uWang Junping, uFan Wen, uWang An, uJing Zhongliang 3 710072, 1 Xi'an: T: ikolishi, iXi'an 710032, ukwakheka okuvulekile kweShanghai kweHaijiao Tong University, Thatha "izingxenye ze-I. kanye nohlelo lwe-CNC" njengento ehlanganisiwe bese ucabanga ukuthi ungathuthukisa kanjani izinga lomsebenzi omuhle. Isu lokulawula uhlelo lwe-CNC olusebenza kahle kakhulu lwesakhiwo esivulekile a: ukwakheka okuvulekile, ukulawula okusebenzayo okuphezulu f uhlelo lwe-CNC 1, inombolo yokuhlukaniswa ecacile kusu lokulawula, idokhumenti ye-tp273, idokhumenti ye-a njengoba i-s medium u level (19h ―), owesilisa (uHan s >. KH, waseHeyang County. Wazalelwa eNtshonalanga. Wazalelwa eNtshonalanga. Ithuluzi lomshini kanye nesistimu yalo yokulawula izinombolo kuya ngesivinini. Intuthuko ehlakaniphile kancane, ehlakaniphile futhi ehlanganisiwe. Inselelo enkulu yenqwaba yobuso ukuqaphela ukuqapha inqubo yokugaya isivinini nokuklama isilawuli sesevisi ye-valve esisekelayo. Kodwa-ke, ukuthuthukiswa kwe-Si kanye nokusetshenziswa kwe-transmitter entsha, i-algorithm yokulawula i-servo ethuthukisiwe kanye nesu lokulawula izinqubo kuthonywe uhlelo lwesistimu yokulawula yendabuko Ngakho-ke, izazi eziningi zizimisele ekusunguleni ukwakheka okusha, okungukuthi, ukwakheka okuvulekile. Leli phepha ligxile ekwakhiweni okuvulekile. Ukuthatha umsebenzi kanye nesistimu yokulawula izinombolo iyonke, ukucabangela indlela yokuthuthukisa ukunemba komshini, nokubeka phambili isu lokulinganisa uhlelo lokulawula izinombolo olungasebenzi kahle esakhiweni esivulekile. I. isingeniso esifushane sokwakheka kwesistimu yokulawula yohlobo lwe-A evulekile. Uhlelo lokulawula izinombolo luyisistimu yekhompyutha ekhethekile yejusi, esetshenziselwa ukulawula insimu yezimboni, kodwa ihlukile kwikhompyutha ejwayelekile. Sekuyisikhathi eside, uhlelo lwezinombolo luye lwathuthuka lwaba uhlelo lwalo. Zisungule isakhiwo sazo sesiqu esithambile, zisebenzise ubumfihlo bobuchwepheshe kanye nokuvalwa kobuchwepheshe, ukuze kube nzima kubakhiqizi bamathuluzi omshini kanye nabasebenzisi bokugcina ukwenza intuthuko yesibili, futhi bathuthukise ikhono lethuluzi lomshini kanye nohlelo lwe-NC. Lapho ithuluzi lomshini wokufundisa nokulawula lingena endaweni yokulawula esakazwayo kanye nesistimu yokukhiqiza ikholomu eguquguqukayo, futhi idinga ngisho nokuxhumana nezinhlelo zenethiwekhi ezivamile njenge-CAD / CAPP / CAM, eminye imishini ye-CNC ehlose imisebenzi yodwa ayanele, kanye nezidingo ezintsha zokugcwalisa imvelo. "Idivayisi iguqulwa ibe uhlelo lwe-CNC oluvulekile."

Ukusabalala, ukusebenzisana kanye nokukhula, okungukuthi, ukuvuleka kwangaphakathi kokwakheka kwesistimu kanye nokuvuleka phakathi kwezingxenye zesistimu. 2. Ngokusho kwenqubomgomo yesistimu, isu lokulawula uhlelo lwe-CNC lokusebenza kwebhasikidi elisekelwe esakhiweni esivulekile lakhiwe izingxenye ezintathu: isilawuli se-servo, i-multi FFI detector kanye nokuhlanganiswa kolwazi, kanye ne-digital value processor, njengoba kuboniswe ku-KL 1, uhlelo lokucubungula i-Chendai lusekelwa uhlelo lwe-tantalum. Ngaphambi kokuba izingxenye zesistimu ye-servo zingadlala indima ebalulekile ye-m ekunemba komsebenzi, izikhungo eziningi zezimboni zihlonyiswe ngezinhlelo ze-servo. Lezi zinhlelo ze-servo m zisebenzisa abalawuli bendabuko be-home 0 anti library, abathandwa kakhulu yizidingo zokuthembeka. Ukulawulwa kwejubane le-classical njenge-oda lomsebenzi akusatholakali - lokhu kulawulwa kokunyakaza okuqinile kokusebenza okuphezulu kubaluleke kakhulu. Inhloso yayo ukuqaphela ukuthi iphutha elihambisanayo elijwayelekile liseduze nentambo yesisombululo se-fi. Ukuze kufezwe ukukhetha okugcwele kwe-europium, njengobunjiniyela, kusenezimpi eziningi ze-peach. I-FT iyimbangela eyinhloko, ikakhulukazi esimweni sokungaqiniseki kokuhlonza okunamandla nokungaqondile m, isilawuli se-servo se-a-speed high degree siklanywe. Uma kusetshenziswa isilawuli se-servo se-bandwidth esilinganiselwe, ukubambezeleka kokuxhuma kwe-europium kuba yimbangela eyinhloko yephutha lesikhundla, okuzothinta izinga lejiyometri lomsebenzi. Uhlelo lwe-flsf kufanele lube nenduku yokulungisa i-cesium kanye nenduku yokusebenza ehlabayo. Lapho amapharamitha e-dynamic system pit eshintsha, ukusebenza kuhle kakhulu. Lawa manethi 1 azoba lukhuni kakhulu ngokwanda kwesivinini sokudla ngesikhathi sokushaywa. Lapho kwakhiwa isilawuli sokuhamba kwenduku esisebenza kahle kakhulu, lawa ma-h rubs kufanele asekelwe ekunxephezelweni kokungqubuzana kokuphakelwa kwe-zinc okuphakanyiswe yi-Colm ne-totnimfca. Isakhiwo sokulawula esiphelele esihlanganisa i-disorder detector, i-position anti library control charmer kanye ne-fractionator, okungukuthi, isistimu efihliwe esebenza kahle kakhulu (i-DOB) esekelwe ku-distration detector, i-Disturbance gauge Isilawuli se-feedforward FFI singasebenzisa i-s-optimal measurement control. Iphutha lesigaba se-Zero lilandelwa yi-W. i-repetitive control skew ukuthuthukisa ukunemba kobubanzi, futhi i-position feedback control ivame ukusebenzisa i-PID control. Ukuze uthole isinxephezelo samandla okungqubuzana okungeyona i-linear, izindlela ezivame ukusetshenziswa yilezi: indlela yesinxephezelo eku-inthanethi esekelwe kumsebenzi we-exponential nonlinear, esekelwe endleleni yesinxephezelo se-Neural network inverse controller, ukulawula okuphindaphindwayo okuqinile kanye nokulawula isakhiwo esiguquguqukayo. Kodwa-ke, lapho amapharamitha esistimu eshintsha kakhulu noma kukhona ukusheshisa okungaguquki endleleni yokunyakaza, i-DOB ayifaneleki kakhulu. UYao noTamizuka baphakamise indlela entsha yokulawula ukunyakaza, okungukuthi ukulawula okuqinile okuguquguqukayo. Uhlelo lwe-servo lokusebenza kwebhasikidi olusekelwe ekulawuleni okuqinile okuguquguqukayo lunokusebenza okuhle kokulandelela.
Ukutholwa kwezinzwa eziningi kanye nokuhlanganiswa kolwazi ekucutshungulweni kokusebenza kwebhasikidi, izindlela ezivamile zokunemba kokucubungula ibhasikidi zifaka ubuchwepheshe bokugwema amaphutha obusekelwe ekunembileni kwethuluzi lomshini webhasikidi kanye nobuchwepheshe bokunxephezela amaphutha obusekelwe ekususeni iphutha ngokwalo. Inhloso yalezi zindlela ezimbili ukunciphisa iphutha lomshini wezingxenye. Leli phepha lithatha umshini wokusebenza kanye nohlelo lwe-NC njengento ehlanganisiwe, licabangela indlela yokuthuthukisa ukunemba komshini webhasikidi, futhi lixhumanisa umshini wokusebenza kanye nohlelo lwe-NC ngokusebenzisa i-Multi-sensor Detection. Uma kuqhathaniswa nohlelo lwe-single sensor, uhlelo lokuhlanganisa ulwazi lwezinzwa eziningi lunezinzuzo zolwazi oluningi, ukubekezelela amaphutha okuhle kanye nokuthola ulwazi oluyisici olungenakutholwa yi-sensor eyodwa. Inqubo yokucubungula iyinqubo eyinkimbinkimbi kakhulu futhi eguquguqukayo, futhi izinguquko zesikhundla, isivinini, izinga lokushisa kanye namandla okusika ziyathintana. Kuphela ngokuqinisa ukuqoqwa, ukuhlonza kanye nokucubungula lolu lwazi kanye nokuthola idatha ethembekile lapho kungalawulwa khona ngendlela efanele. Izimpawu ezihambisanayo zilinganiswa yizinzwa ezahlukahlukene, bese kusetshenziswa ubuchwepheshe bokuhlanganisa ulwazi lwezinzwa eziningi ukuzwa ulwazi lwesimo sokucubungula, ukuze kunikezwe isilawuli ulwazi lwangempela noluthembekile oluphelele futhi kuthuthukiswe ukunemba kokulawula.
Njengoba isidingo sokwanda kwesivinini nesikhathi sangempela sokucubungula ulwazi lwesistimu, kanye nokuthuthukiswa kwamasekethe amakhulu ahlanganisiwe, kunezinhlobo ezahlukene zama-chip i-DSP ezinikezelwe ekucubungulweni kwesignali yedijithali yesikhathi sangempela. Uma kuqhathaniswa nama-microprocessor ajwayelekile, izici zawo eziyinhloko zimbili: iningi lama-chip e-DSP lisebenzisa isakhiwo saseHarvard, okungukuthi, indawo yokugcina imiyalelo yohlelo kanye nedatha ihlukanisiwe, futhi ngalinye linekheli lalo kanye nebhasi ledatha, okwenza imiyalelo yokucubungula kanye nedatha kungenziwa ngesikhathi esifanayo, okuthuthukisa kakhulu ukusebenza kahle kokucubungula; Lapho i-microprocessor ejwayelekile ikhipha umyalelo, idinga imijikelezo eminingana yemiyalelo ukuze iwuqede. I-chip ye-DSP isebenzisa ubuchwepheshe bepayipi. Nakuba isikhathi sokuqalisa somyalelo ngamunye siseyimijikelezo eminingana yemiyalelo, ngenxa yokuhamba kwemiyalelo, uma ihlanganiswa, isikhathi sokugcina sokuqalisa somyalelo ngamunye siqedwa ngomjikelezo owodwa wemiyalelo.
Kuhlelo lokulawula ngezinombolo, iprosesa yesignali yedijithali iqedela imisebenzi yokutholwa kwedatha, ukwenziwa kwezindlela, ukukhethwa kwamasu okulawula kanye nokulawula ngesikhathi sangempela.
3 isiphetho kusukela ezidingweni zomshini wokulungisa ngokunemba kwebhasikidi, leli phepha lithatha umsebenzi kanye nohlelo lwe-NC njengento ehlanganisiwe ngokusebenzisa ubuchwepheshe bokuhlanganisa ulwazi lwezinzwa eziningi, licabangela indlela yokuthuthukisa ukunemba komshini wokulungisa ngebhasikidi, futhi libeka phambili isu lokulawula uhlelo lwe-NC Performance lwebhasikidi olusekelwe esakhiweni esivulekile. Leli cebo liwusizo futhi ekulawuleni ezinye izidalwa ezihambayo.
