Uphando malunga nesicwangciso solawulo lwenkqubo ephezulu ye-CNC esekelwe kuyilo oluvulekileyo lwe-Wang Junping, i-Fan Wen, i-Wang An, i-Jing Zhongliang 3 710072, i-1 Xi'an: ikholeji, i-Xi'an 710032, i-Shanghai backbone open architecture yeYunivesithi yase-Haijiao Tong, Thatha "I. iinxalenye kunye nenkqubo ye-CNC" njengento edibeneyo kwaye ucinge ngendlela yokuphucula i-degree yomsebenzi omhle.I-Cha arr7 isicwangciso solawulo lwenkqubo ye-CNC ephezulu yokusebenza kwesakhiwo esivulekileyo a: i-architecture evulekileyo, ulawulo oluphezulu lwenkqubo ye-CNC ye-1, inombolo ecacileyo yokuhlelwa kwisicwangciso solawulo, uxwebhu lwe-tp273, a njenge-s medium u level (19h -), indoda (Han s > KH, ukusuka Heyang County Wazalelwa eNtshona Isixhobo sokulawula amanani ahamba ngesantya esingaphezulu, esikrelekrele kunye nophuhliso oludibeneyo ingqumba yobuso kukuqonda ukujongwa kwenkqubo yomatshini wesantya kunye noyilo lolawulo lwenkonzo yevalvu exhasayo, nangona kunjalo, uphuhliso lweSi kunye nokusetyenziswa kwe-transmitter entsha, i-algorithm yolawulo lwe-servo kunye nesicwangciso solawulo lwenkqubo ziye zaphenjelelwa yinkqubo yolawulo lwemveli. Ke ngoko, abaphengululi abaninzi bazibophelele ekusekeni i-architecture entsha, oko kukuthi, i-architecture evulekileyo Eli phepha ligxininisa kwi-architecture evulekileyo kunye nenkqubo yokulawula amanani ngokubanzi, ngokuqwalasela indlela yokuphucula ukuchaneka komatshini, kunye nokubeka phambili isicwangciso sokulinganisa. yenkqubo yolawulo lwamanani engasebenziyo kwisakhiwo esivulekileyo.I. Intshayelelo emfutshane yoyilo lwenkqubo yolawulo evulekileyo yohlobo lwe-A.Inkqubo yolawulo lwamanani yinkqubo ekhethekileyo yekhompyutheni yejusi, esetyenziselwa ukulawula indawo yoshishino, kodwa ihluke kwikhompyutheni jikelele.Ixesha elide, inkqubo yamanani iphuhliswe ibe yinkqubo yayo.Ukuseka i-stem yabo yesakhiwo esithambileyo, ukuphumeza imfihlo yobugcisa kunye nokutywinwa kobugcisa, ukuze kube nzima kubavelisi bezixhobo zoomatshini kunye nabasebenzisi bokugqibela ukwenza uphuhliso lwesibini, nokuphuhlisa isakhono sesixhobo somatshini kunye nenkqubo ye-NC.Xa isixhobo somatshini wokufundisa kunye nolawulo singena kwindawo yolawulo esasazwayo kunye neguquguqukayo yenkqubo yokuvelisa ikholamu, kwaye ifuna unxibelelwano kunye neenkqubo zothungelwano eziqhelekileyo ezifana neCAD / CAPP / CAM, Ezinye izixhobo ze-CNC ezijoliswe kwimisebenzi yodwa akwanelanga, kwaye entsha iimfuno zokuzaliswa kokusingqongileyo."Isixhobo siphinde siguqulwe sibe yinkqubo ye-CNC evulekileyo.
I-architecture evulekileyo ye-Yi Trent ithatha i-block hierarchical junction ye-HN kwaye ibonelela ngodibaniso lwesicelo esidibeneyo P ngokusebenzisa iifom ezahlukeneyo, eziphathwayo.
I-Scalability, ukusebenzisana kunye nokulinganisa, oko kukuthi, ukuvuleka kwangaphakathi kokubunjwa kwenkqubo kunye nokuvuleka phakathi kwamacandelo enkqubo.2. Ngokomgaqo-nkqubo wenkqubo, isicwangciso solawulo lwenkqubo yebhasikithi ye-CNC esekelwe kwisakhiwo esivulekileyo siqulunqwe ngamacandelo amathathu: isilawuli se-servo, i-multi-FFI detector kunye nokudibanisa ulwazi, kunye neprosesa yexabiso ledijithali, njengoko kubonisiwe kwi-KL 1, inkqubo yokucubungula i-Chendai. ixhaswa yinkqubo yetantalum.Ngaphambi kokuba amacandelo enkqubo ye-servo adlale indima ebalulekileyo ekuchanekeni kwendawo yokusebenza, amaninzi amaziko oshishino axhotyiswe ngeenkqubo ze-servo.Ezi nkqubo ze-servo m zisebenzisa ikhaya lemveli 0 abalawuli bethala leencwadi, ezithandwa ngakumbi kunye neemfuno zokuthembeka.Ulawulo lwesantya classical ezifana oda umsebenzi ayisekho - s le high-ukusebenza robust ulawulo intshukumo kubaluleke kakhulu.Injongo yayo kukuqonda ukuba impazamo ye-nominal conngruence isondele kumtya wesisombululo se-fi.Ukuze uqaphele ukhetho olupheleleyo lwe-europium, njengobunjineli, kusekho iimfazwe ezininzi zeepesika.I-FT sesona sizathu siphambili, ngakumbi kwimeko ye-anti dynamic kunye ne-nonlinear yokuchonga ukungaqiniseki m, i-a-speed high degree servo controller iyilwe.Xa isilawuli se-servo esilinganiselweyo sisetyenzisiweyo, ukulibaziseka kokudibanisa kwe-europium kuba yimbangela ephambili yephutha lesikhundla, eliya kuchaphazela idigri yejometri ye-workpiece.Inkqubo ye-flsf kufuneka ibe ne-cesium fixing rod kunye ne-performance sting rod.Xa iiparameters zenkqubo eguquguqukayo emhadini itshintsha, Ukusebenza kuhle kakhulu.Le minatha ye-1 iya kuba ngqongqo ngakumbi ngokunyuka kwesantya sokutya ngexesha lokubetha.Xa uyila i-high-performance rod motion controller, ezi rubs h kufuneka zisekelwe kwimbuyekezo ye-zinc feed friction ecetywayo yi-Colm kunye ne-totnimfca.Ulwakhiwo lolawulo lulonke oludibanisa umtshini wokuphazamiseka, indawo echasene nethala leencwadi elicharmer kunye ne-fractionator, oko kukuthi, inkqubo engcwatywayo yokusebenza ephezulu (DOB) esekwe kwisixhobo sokuphazamiseka, igeyiji yokuphazamiseka Umlawuli weFFI we-feedforward unokusebenzisa ulawulo lokulinganisa olululo. .Ukulandelela impazamo yesigaba se-Zero W. ukuphindaphinda ulawulo lwe-skew ukuphucula ukuchaneka koluhlu, kunye nolawulo lwempendulo yesikhundla ngokuqhelekileyo yamkela ulawulo lwe-PID.Ukufumana imbuyekezo yamandla e-friction nonlinear, iindlela ezisetyenziswa ngokuqhelekileyo zezi: indlela yembuyekezo ye-intanethi esekelwe kwi-exponential nonlinear function, ngokusekelwe kwindlela yembuyekezo ye-Neural network inverse control compensation, ukulawulwa okuphindaphindiweyo okunamandla kunye nokulawulwa kwesakhiwo esiguquguqukayo.Nangona kunjalo, xa iiparameters zesistim zitshintsha kakhulu okanye kukho ukukhawulezisa okungapheliyo kwi-trajectory ye-motion, i-DOB ayifanelekanga kakhulu.I-Yao kunye ne-tamizuka bacebise indlela entsha yokulawula intshukumo, eyile, ulawulo oluluqilima.Inkqubo ye-servo yokusebenza kwebhaskithi esekwe kulawulo oluluqilima oluguquguqukayo inomsebenzi olungileyo wokulandela umkhondo.
Ukufumanisa i-sensor ye-multi-sensor kunye ne-fusion yolwazi kwi-processing performance processing, iindlela eziqhelekileyo zokuchaneka kwe-basket processing zibandakanya iteknoloji yokuphepha impazamo esekelwe ekuchanekeni kwesixhobo somatshini webhasikithi kunye neteknoloji yembuyekezo yephutha esekelwe ekupheliseni impazamo ngokwayo.Injongo yezi ndlela zimbini kukunciphisa impazamo yomatshini yamacandelo.Eli phepha lithatha i-workpiece kunye nenkqubo ye-NC njengento yonke edibeneyo, iqwalasela indlela yokuphucula ukuchaneka kwe-basket machining, kwaye idibanisa i-workpiece kunye nenkqubo ye-NC ngokusebenzisa i-Multi-sensor Detection.Xa kuthelekiswa nenkqubo ye-sensor enye, inkqubo yokudibanisa ulwazi lwe-multi-sensor ineenzuzo zolwazi oluninzi, ukunyamezela okulungileyo kunye nokufumana ulwazi lweempawu ezingenakufunyanwa yinzwa enye.Inkqubo yomatshini yinkqubo enzima kakhulu kwaye iyatshintsha, kwaye utshintsho lwendawo, isantya, ubushushu kunye namandla okusika kuchaphazela omnye nomnye.Kuphela ngokuqinisa ukuqokelela, ukuchongwa kunye nokucubungula olu lwazi kunye nokufumana idatha ethembekileyo inokulawulwa ngokuchanekileyo.Izibonakaliso ezihambelanayo zilinganiswa ngeendlela ezahlukeneyo zoluvo, kwaye emva koko iteknoloji ye-multi-sensor yolwazi lwe-fusion isetyenziselwa ukuva i-processing state information, ukwenzela ukuba unikeze umlawuli ngolwazi lokwenene noluthembekileyo olubanzi kunye nokuphucula ukuchaneka kolawulo.
Ngokunyuka kwemfuno yesantya kunye nexesha lokwenyani lokusetyenzwa kolwazi lwenkqubo, kunye nophuhliso lweesekethe ezinkulu ezihlanganisiweyo, kukho iitshiphusi ezahlukeneyo ze-DSP ezinikezelwe ekusetyenzweni komqondiso wedijithali ngexesha lokwenyani xa kuthelekiswa ne-microprocessors yenjongo ngokubanzi, iimpawu zayo eziphambili. zimbini: iitshiphusi ezininzi ze-DSP zamkela ubume beHarvard, oko kukuthi, indawo yokugcina imiyalelo yenkqubo kunye nedatha yahluliwe, kwaye nganye inedilesi yayo kunye nebhasi yedatha, eyenza imiyalelo yokucubungula kunye nedatha inokuqhutywa ngaxeshanye, nto leyo iphucula kakhulu ukusebenza kakuhle;Xa i-microprocessor yenjongo ngokubanzi iphumeza umyalelo, ifuna imijikelo yemiyalelo emininzi ukuyigqiba.I-chip ye-DSP yamkela iteknoloji yombhobho.Nangona ixesha lokwenziwa komyalelo ngamnye liseyimijikelo yomyalelo eliqela, ngenxa yokuhamba kwemiyalelo, ethatyathwe kunye, ixesha lokugqibela lokwenziwa komyalelo ngamnye ligqityezelwa kumjikelo omnye womyalelo.
Kwinkqubo yolawulo lwamanani, iprosesa yesignali yedijithali igqiba imisebenzi yokufumana idatha, ukuveliswa kwendlela, ukukhethwa kweqhinga lokulawula kunye nokulawula ixesha langempela.
Isiphelo se-3 siqala kwiimfuno ze-basket precision machining, eli phepha lithatha i-workpiece kunye nenkqubo ye-NC njengento yonke edibeneyo ngokusebenzisa i-multi-sensor yolwazi lwe-teknoloji ye-fusion, iqwalasela indlela yokuphucula ukuchaneka kwe-basket machining, kwaye ibeka phambili isicwangciso solawulo lwe-basket Performance NC inkqubo. ngokusekelwe kwisakhiwo esivulekileyo.Esi sicwangciso sikwabalulekile kulawulo lweminye imizimba ehambayo.
