Kev tshawb nrhiav tshiab thiab kev tsim kho tau muaj peev xwm ua lub hauv paus tseem ceeb uas txwv rau kev tsim kho kev lag luam
Tom qab xyoo caum ntawm txoj kev loj hlob, kev siv thev naus laus zis thiab kev tsim muaj peev xwm ntawm kev lag luam tshuab hosiery tshuab tau mus txog qib tshiab. Tab sis cov teeb meem cuam tshuam kuj pom tseeb. Nrog kev nrov ntawm hosiery tshuab kev tsim tshuab thiab kev nthuav dav txuas ntxiv ntawm kev tsim muaj peev xwm, qhov kev thov hauv kev lag luam thom khwm tau pib ua tiav. Nyob rau hauv ib puag ncig zoo li no, homogeneous tsis muaj nqi sib tw los ua ntau dua thiab hnyav dua. Kev cog qhov nyiaj tau zoo dhau ntawm cov lag luam, ntau lub chaw lag luam me thiab nruab nrab tau ua nyuaj. Qhov laj thawj tseem ceeb rau qhov tshwm sim no tseem yog tias peb txoj kev tshawb nrhiav tshiab thiab kev tsim kho muaj peev xwm tsis muaj zog, thiab txoj kev loj hlob sai ntawm kev lag luam tau ua rau cov tshuab hosiery tshuab tuam txhab tau nrawm mus cuag ib qho kev txwv tsis pub dhau thiab nws nyuaj rau hla.
Nyob rau tam sim no, yuav luag tag nrho ntawm cov hluav taws xob hauv tsev hluav taws xob hauv tsev tswj kev siv hluav taws xob tswj hwm kev tswj hwm, uas koom tes nrog servo system. Lub kaw lus servo sai, ruaj khov thiab raug txiav txim ntau cov lus txib uas tau tshaj tawm los ntawm lub khoos phis tawj. Tam sim no, feem ntau ntawm cov servos tau rau lub tshuab hosiery kev lag luam. Txhawm rau kom ua tiav kev ruaj khov thiab ruaj khov thaum lub sij hawm tig ceev, tab sis qhov nrawm tseem tsis muaj qee qhov" cua sov", ua rau kev saib xyuas txhua lub sijhawm hloov, uas yog, ntawm txoj haujlwm qhov twg cov txheej txheem yuav tsum nres, lub cev muaj zog txuas mus ntxiv Cov. Qee qhov deb.
Ua cov lej, pes tsawg lub thom khwm koj ua tsawg dua txhua hnub?
Txawm hais tias qhov kev lag luam tam sim no tseem zoo, muaj tus saib xyuas ntawm txog 5 tus kav, thiab muaj 10 tus hlua ib zaug thiab ib zaug. Lub sijhawm ntawm 10 tus hlua no yog khib. Raws li kev txheeb cais, qhov ua tau zoo ntawm kev daws cov teeb meem overshoot tau nce ntxiv 4% - 6%. Coj cov thom khwm lub voj voos tshaj plaws ua piv txwv. Lub sijhawm siv los ua thom khwm yog 145 vib nas this. Ib lub tshuab tuaj yeem tsim tau 595 thom khwm 24 teev nyob rau ib hnub. Nws yog txhawm cia muab xam rau 4%. Yog tias tsis muaj kev tshaj li, nws tuaj yeem tsim 23 qhov thom khwm ib hnub. Rau cov thom khwm, yog cov thom khwm Hoobkas muaj 100 lub tshuab, nws tuaj yeem tsim 2300 ntau tus thom khwm ib hnub. Kev siv nyiaj ntau tshaj plaws ntawm cov thom khwm tam sim no yog kev ua haujlwm, yog li kev txhim kho cov kev ua tau zoo ntawm 10 tus hlua yog qhov tseem ceeb tshaj plaw.
Yuav ua li cas los daws cov teeb meem kis las?
Kev saib xyuas cov teeb meem zoo li yooj yim, tab sis nws yog qhov tseeb teeb meem heev, vim hais tias lub koos pij tawj siv cov pulses los tswj qhov pib thiab nres ntawm servo, tab sis lub koos pij tawj yuav tsum tsis txhob xa cov pulses thaum lub cev muaj zog. Lub kaw lus servo muaj cov txheej txheem deceleration los ntawm kev ua haujlwm siab nrawm rau nres. Hauv kev txiav txim siab nruj, qhov txheej txheem deceleration no yog qhov kev ncua deb ntawm overshoot. Yog hais tias lub servo nruj dhau lawm thiab nres nrawm nrawm, nws yuav muaj kev cuam tshuam ntau dua rau lub tshuab thaum lub sij hawm sib hloov ceev thiab txo cov kev pab lub neej ntawm kev hloov kho tshuab. Qhov no tsis tsim nyog rau ob lub tshuab tsim khoom tsim thiab tus neeg siv kawg.
Yuav kom daws tau cov teeb meem overshoot, txhua qhov kev sib xyaw thiab kev lag luam servo tau sim ntau xyoo los ua pov thawj tias cov kev cai tswj hwm ib txwm nyuaj ua kom tiav. Qhov tseeb, daws qhov teeb meem no tsis yog qhov nyuaj hauv kev tshawb xav, uas yog, los xyuas kom meej tias lub cev muaj zog mus txog ntawm txoj haujlwm pej xeem, tab sis tseem yuav txuag lub sijhawm, tsuas yog cia servo nres lub sijhawm ua ntej, ua ntej tshaj qhov deb deb deb deb, thiab xyuas kom meej tias txoj haujlwm tuaj yeem hu tau. Kev ua kom tau zoo ntawm cov servo cov kab ke yog qhov yuav tsum tau, thiab kev sib koom tes sib sib zog nqus ntawm cov koos pis tawj system thiab servo manufacturers yuav tsum.
Yuav ua li cas los nrhiav qhov chaw sib xws thaum khaws cia sib txawv hauv" Trinity" sib sib zog nqus kev koom tes?
Tam sim no, kev tswj hluav taws xob ntawm tag nrho kev lag luam yog nyob rau hauv kev siv ntawm lub tshuab kaw lus uas tau sau ntau ntawm cov thev naus laus zis. Lawv muaj ntau lub xyoos ntawm cov thev naus laus zis thev naus laus zis thiab kev paub dhau los, tab sis lawv tsis tshaj lij rau kev siv servo; feem ntau ntawm cov servo cov tuam txhab yog cov ua haujlwm dav dav servo cov nkag mus hauv kev lag luam. Cov khoom thev naus laus yuav luag yog xim dub ntawm' s ob lub qhov muag. Qhov no tsim qhov xwm txheej uas cov generals ntawm kev lag luam tsis paub cov tub rog, thiab cov tub rog tsis paub tus generals. Nws yog qhov nyuaj kom ua tiav kev koom tes tob tob kev qhia txuj ci thiab tsis tuaj yeem tsoo los ntawm cov kev thaiv kev uas twb muaj lawm.
Nrog rau kev sib tw ua lag luam hauv kev lag luam nce ntxiv, cov neeg siv yuav zam kev ua tiav ntawm cov thev naus laus zis siab dua thiab tsim nyog tus nqi tsim nyog rau cov khoom xav tau. Kaum ob ntawm cov thom khwm hauv tsev siv tshuab, loj thiab me me, txhua tus tab tom nrhiav kev daws teeb meem tshiab. Blindly cia siab rau cov qauv txawv teb chaws mus rau" rov ua dua tshiab" yuav zam kev nkag mus rau tom ntej tsim nqi-kev sib tw ib puag ncig. Qhov kev koom tes sib sib zog nqus ntawm cov tshuab ua lag luam, cov tshuab hluav taws xob tswj kev lag luam, thiab cov tuam txhab servo yog qhov tseem ceeb. Puas muaj leej twg tuaj yeem ua txhaum txoj kev lag luam ib txwm sib txawv ua ntej, leej twg yuav ua tus thawj coj hauv kev sib tw hnyav dua tom ntej? Txoj kev loj hlob zoo li kev caij nkoj tawm tsam tam sim no. Yog koj tsis npaj ua ntej, koj yuav thim rov qab. Yog tias koj xav tau ntawm cov chaw tsim khoom lag luam qub thiab cov hom kev lag luam, thiab tsis nquag hloov txoj kev mus nrhiav cov kev sib tawg, qhov xwm txheej yuav loj dua.
