Research on control strategy of high performance CNC system based on openarchitecture 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, Tengani "I. mbali ndi CNC dongosolo" monga ogwirizana lonse ndi kuganizira mmene kusintha s digiri ya ntchito zabwino.Cha arr7 mkulu-ntchito CNC dongosolo kulamulira dongosolo la dongosolo lotseguka: zomangamanga lotseguka, mkulu-ntchito kulamulira f CNC dongosolo 1, gulu bwino m'gulu njira ulamuliro, tp273 chikalata, monga s sing'anga u mlingo (19h ―), mwamuna (Han s >. KH, wochokera ku Heyang County mulu wa nkhope ndikuzindikira kuwunika kwa makina othamanga ndikupanga chowongolera chothandizira cha valve Komabe, chitukuko cha Si ndi kugwiritsa ntchito transmitter yatsopano, ma aligorivimu owongolera a servo ndi njira yowongolera njira zakhudzidwa ndi dongosolo lakale lowongolera. Choncho, akatswiri ambiri akudzipereka kuti akhazikitse kamangidwe katsopano, ndiko kuti, kamangidwe kameneka kamayang'ana pa zomangamanga zotseguka, ndikuganizira momwe mungasinthire kulondola kwa makina. ya off-performance manambala kulamulira dongosolo mu dongosolo lotseguka.I. Chidule chachidule cha kamangidwe ka dongosolo lotseguka la mtundu wa A.Dongosolo lowongolera manambala ndi pulogalamu yapadera yamakompyuta yamadzi, yomwe imagwiritsidwa ntchito poyang'anira gawo la mafakitale, koma ndi yosiyana ndi makompyuta wamba.Kwa nthawi yayitali, dongosolo la manambala lapangidwa kukhala dongosolo lake.Khazikitsani mawonekedwe awo ofewa tsinde, gwiritsani ntchito chinsinsi chaukadaulo ndi kusindikiza ukadaulo, kuti zikhale zovuta kwa opanga zida zamakina ndi ogwiritsa ntchito kumapeto kuti achite chitukuko chachiwiri, ndikukulitsa luso la chida cha makina ndi dongosolo la NC.Pamene chiphunzitso ndi kulamulira makina chida akulowa kugawira ulamuliro ndi kusinthasintha ndime kupanga dongosolo chilengedwe, ndipo amafuna kulankhula ndi machitidwe wamba maukonde monga CAD / CAPP / CAM, Ena CNC zida umalimbana ntchito paokha sikokwanira, ndi latsopano zofunika kudzaza chilengedwe."Chidacho chimasinthidwanso kukhala makina otseguka a CNC.
Zomangamanga zotseguka za Yi Trent zimatengera njira yolumikizirana ndi HN ndipo imapereka kulumikizana kolumikizana kwa P kudzera mumitundu yosiyanasiyana, yomwe imatha kunyamula.
Scalability, interoperability ndi scalability, ndiko kuti, kutsegukira mkati mwa dongosolo zikuchokera ndi omasuka pakati pa zigawo zikuluzikulu za dongosolo.2. Malinga ndi ndondomeko ya dongosolo, basket performance CNC system control strategy based on open structure imapangidwa ndi magawo atatu: servo controller, multi FFI detector ndi kuphatikiza chidziwitso, ndi digito mtengo purosesa, monga momwe KL 1, Chendai processing dongosolo. imathandizidwa ndi tantalum system.Zida za servo zisanakhale ndi gawo lofunikira pakulondola kwa chogwirira ntchito, malo ambiri ogulitsa amakhala ndi makina a servo.Machitidwe a servo m awa amagwiritsa ntchito olamulira kunyumba 0 otsutsa laibulale, omwe amadziwika kwambiri ndi zofunikira za kukhulupirika.Kuwongolera kwa liwiro lachikale monga dongosolo la ntchito sikuliponso - s kuwongolera koyenda kolimba kwambiri kumeneku ndikofunikira kwambiri.Cholinga chake ndikuzindikira kuti cholakwika chodziwika bwino chili pafupi ndi chingwe chowongolera.Pofuna kuzindikira chisankho chonse cha europium, monga engineering, pali nkhondo zambiri za pichesi.FT ndiye chifukwa chachikulu, makamaka pankhani ya kusatsimikizika kwa anti dynamic and nonlinear m, wowongolera a-speed high degree servo adapangidwa.Pamene chowongolera chochepa cha bandwidth servo chikugwiritsidwa ntchito, kuchedwa kwa europium coupling kumakhala chifukwa chachikulu cha zolakwika za malo, zomwe zidzakhudza digiri ya geometric ya workpiece.Dongosolo la flsf liyenera kukhala ndi ndodo yokonzera cesium ndi ndodo yoluma.Pamene magawo a dzenje lamphamvu akusintha, Ntchitoyi ndi yabwino kwambiri.Maukonde awa 1 adzakhala okhwima kwambiri ndi kuwonjezeka kwa liwiro la chakudya panthawi ya slam.Popanga zowongolera zoyenda bwino kwambiri, ma h rubs awa akuyenera kutengera chiwongola dzanja cha zinc feed chomwe Colm ndi totnimfca adapereka.Kapangidwe kake kamene kamaphatikiza chowunikira chosokoneza, chowongolera chowongolera laibulale yaposachedwa ndi chowongolera, ndiye kuti, kachitidwe kapamwamba kamene kamayikidwa m'manda (DOB) kutengera chowunikira chosokoneza, chowerengera chosokoneza The feedforward FFI controller amatha kutengera s-mulingo woyenera kuyeza. .Kutsata zolakwika za zero gawo W. kubwereza mobwerezabwereza kuwongolera skew kuwongolera kulondola kwamitundu, ndipo kuwongolera mayankho a malo nthawi zambiri kumatengera kuwongolera kwa PID.Pakulipidwa kwamphamvu yosagwirizana ndi mikangano, njira zomwe zimagwiritsidwa ntchito nthawi zambiri ndi izi: njira zolipirira pa intaneti potengera mawonekedwe osasinthika, kutengera njira ya Neural network inverse controller compensation, kuwongolera kubwereza kwamphamvu komanso kuwongolera mawonekedwe.Komabe, pamene magawo a dongosolo asintha kwambiri kapena pali kuthamangitsidwa kosalekeza mumayendedwe oyenda, DOB siyoyenera kwambiri.Yao ndi tamizuka anakonza njira yatsopano yoyendetsera kayendetsedwe kake, yomwe ndi adaptive robust control.Dongosolo la basket performance servo yotengera kuwongolera kokhazikika kumakhala ndi ntchito yabwino yotsata.
Kuzindikira kwa ma sensor ambiri ndi kuphatikizika kwa zidziwitso pakukonza magwiridwe antchito, njira zodziwika bwino zamabasiketi olondola zimaphatikizira ukadaulo wopewera zolakwika potengera kulondola kwa chida cha makina a basket ndi ukadaulo wolipira zolakwika potengera kuthetsa cholakwikacho.Cholinga cha njira ziwirizi ndikuchepetsa zolakwika za makina a magawo.Pepalali limatenga workpiece ndi NC dongosolo lonse logwirizana, limayang'ana momwe mungasinthire kulondola kwa makina a basket, ndikulumikiza workpiece ndi NC system kudzera mu Multi-sensor Detection.Poyerekeza ndi single sensor system, multi-sensor information fusion system ili ndi zabwino zambiri, kulolerana kwabwino komanso kupeza chidziwitso chomwe sichingapezeke ndi sensor imodzi.Njira yopangira makina ndizovuta kwambiri komanso zosinthika, ndipo kusintha kwa malo, liwiro, kutentha ndi mphamvu yodula zimakhudzana.Pokhapokha polimbitsa kusonkhanitsa, kuzindikiritsa ndi kukonza zidziwitsozi ndikupeza deta yodalirika zingathe kuyendetsedwa molondola.Zizindikiro zofananira zimayesedwa ndi masensa osiyanasiyana, ndiyeno ukadaulo wophatikizira chidziwitso chamitundu yambiri umagwiritsidwa ntchito kuzindikira zidziwitso za boma, kuti apatse woyang'anira chidziwitso chenicheni komanso chodalirika chokwanira ndikuwongolera kulondola kowongolera.
Ndi kuchuluka kwa kufunikira kwa liwiro komanso nthawi yeniyeni ya kukonza zidziwitso zamakina, komanso ndikukula kwa mabwalo akulu akulu ophatikizika, pali tchipisi tambiri ta DSP yodzipereka pakukonza ma siginecha a digito Poyerekeza ndi ma microprocessors acholinga chonse, mawonekedwe ake akulu. awiri: Tchipisi zambiri za DSP zimatengera kapangidwe ka Harvard, ndiko kuti, malo osungiramo malangizo a pulogalamu ndi data amalekanitsidwa, ndipo aliyense ali ndi adilesi yake ndi basi ya data, zomwe zimapangitsa kuti malangizo ndi data azichitika nthawi imodzi. amene kwambiri bwino processing Mwachangu;Pamene microprocessor-purpose-purpose ikupereka malangizo, imafunika maulendo angapo kuti amalize.Chip cha DSP chimagwiritsa ntchito ukadaulo wamapaipi.Ngakhale kuti nthawi yoperekera malangizo aliwonse ikadali mikombero ingapo ya malangizo, chifukwa cha kuyenda kwa malangizo, kutengedwa palimodzi, nthawi yomaliza ya malangizo aliwonse imatsirizidwa munjira imodzi ya malangizo.
Mu dongosolo lowongolera manambala, purosesa ya digito ya digito imamaliza ntchito zopezera deta, kupanga ma trajectory, kusankha njira zowongolera ndi kuwongolera nthawi yeniyeni.
3 mapeto kuyambira pa zofunika za basket mwatsatanetsatane machining, pepala ili amatenga workpiece ndi NC dongosolo monga ogwirizana lonse kudzera mu multi-sensor zambiri maphatikizidwe luso machining, amaona mmene kusintha basket Machining mwatsatanetsatane, ndi kuika patsogolo njira yolamulira basket Performance NC dongosolo. kutengera mawonekedwe otseguka.Njirayi ndi yofunikanso pakuwongolera matupi ena oyenda.
