Yuav ua li cas los tswj tus tswj algorithm ntawm stepper tsav ntau zoo
Nyob hauv optimizing cov qauv siv rau kev tswj tsa suab raws li cov cav hlau theem nrab, engineers yuav tsum xav txog cov nqi xws li nqi, kev ua haujlwm, kev ua haujlwm, kev xav tsis txaj muag (xws li cov neeg ua hauj lwm tswj), thiab kev tsim kho lub sijhawm. Kev tswj cov cuab yeej tam sim no muaj kev sib tw ntawm kev khiav hauj lwm rau ntau yam kev phom sij, thiab qhov kev ntsuam xyuas tag nrho ntawm cov kev daws teeb meem yog feem ntau txwv ntawm cov txheej xwm phem tshaj plaws uas raug cuam tshuam los ntawm tag nrho lub cev. Adaptive tswj algorithms yog qhov tseem ceeb rau kev tawm qhov siab tshaj plaws ntawm kev ua haujlwm ntawm qhov chaw ua haujlwm zoo.
Qhov system zauv
Yog tias koj xav tau qhov siab tshaj plaws, koj yuav tsum qhia txog tus cwj pwm txawv ntawm tag nrho cov tshuab electromechanical. Txhua qhov kev hloov zog yuav tsum raug xam tias: ntsuas kub, mechanical degradation, acceleration, ceev, muab hluav taws xob, thiab lwm yam. Lub tshuab architecture kuj muaj feem xyuam rau nws.
Nyob rau hauv qhib-voj systems, nws yog feem ntau tsim nyog yuav tsum tau ua kom muaj lub cav nrog qhov phem tshaj plaws tam sim no tsav tsheb thiab kev ceev ceev, yog li peb muaj peev xwm xav tias kev ua hauj lwm tsis yog lub hom phiaj tsim lub hom phiaj no. Hom kev tshuaj ntsuam no yog siv sij hawm ntau heev vim hais tias lub kaw lus yuav tsum tau xyuas tias muaj tseeb ntawm txhua qhov hluav taws xob, qhov kub thiab txias qhov tseem ceeb uas lub tshuab yuav siv los txo cov kev pheej hmoo ntawm kev sib luag. Txhua qhov kev ua tiav cov hlab pas yuav muaj peev xwm rov ua tau dua, feem ntau vim nws ua hauj lwm ntawm (los yog ze rau) ntau zaus ntawm lub cav. Tsis txhob cuam tshuam cov chaw no yog qhov tseem ceeb heev vim hais tias cov resonance tuaj yeem ua rau lub cev quab yuam los yog nkag mus rau ib qho mob. Txawm li cas los xij, rau cov voj voog qhib, txiav txim rau cov chaw no yuav nyuaj heev.
Kaw lub voj kev kaw lus feem ntau yuav siv ob hom: qhov system sensor (lub teeb los yog cov nyhuv huv) thiab qhov system tsis paub tseeb. Lub tshuab tsis muaj lub tshuab tsis zoo, kuj hu ua "lub voj voog semi-closed", feem ntau yog siv cov hluav taws xob generated ntawm lub cav coils li kev tawm tswv yim. Sensor-based tswj systems yog dav siv, tab sis lwm cov kev hloov rau lub sensor yuav tsum tau muab xav rau hauv kev xyaum xyaum. Ib qho zoo ntawm lub tshuab tsis muaj lub zog yog tias lawv tsuas xav nyeem cov lus qhia txog lub cev lus ntawm lub cev. Ib qho tseem ceeb kom zoo dua yog qhov txo tus nqi ntawm kev kaw-loop los yog ib lub voj kab nrib ib nrab, thaum txo qhov nyuaj ntawm lub system los ntawm kev xa mus rau sab nraud sensors. Cov qauv zoo tsim nyog yuav tsum muaj kev to taub txog cov yam ntxwv ntawm daim npav EMF.
SLA kuas
Rov qab EMF facilitates extraction ntawm cov ncauj lus kom ntxaws txog cov lus taw kev ntawm lub tshuab electromechanical thiab muab cov ntaub ntawv tshawb nrhiav. Ib qho hluav taws xob yog tsim los ntawm kev tsav tsheb tam sim no pulses ntawm lub cav thiab lub zog ntawm lub cav coil los ntawm kev sib nqus field ntawm lub cev. Cov ntaub ntawv no feem ntau yog hu ua qhov ceev thiab / lossis lub kaum ntse ntse (SLA) ntawm lub tshuab. Qhov kev tshaj tawm ntawm cov theem pib ntawm qhov tob tshaj plaws yog qhov ntsuas ntawm qhov loj ntawm EMF rov qab.
Daim duab 1 qhia tau hais tias qhov khawm SLA thaum tsav tsheb kauj vab uas tau siv rau hauv tshuab fais fab uas siv cov As-30522 subdivided stepper motor controller. Cov ntaub ntawv no tau sau thaum lub sij hawm cheb ntawm NXT cov tswv yim (lub tswv yim teev uas txiav txim siab rau kev tsav tsheb excitation ceev). Thaum nws tsiv ntawm sab laug mus rau sab xis, qhov ua rau qhov kev sib tw nce tuaj thiab koj tuaj yeem pom qhov chaw ua haujlwm txawv. Lub peev xwm los ntsuas tus qauv yam ntxwv ntawm tag nrho lub zog yog ib qho tseem ceeb ntawm cov koob yees duab-A-305xx-tshwj xeeb tshaj yog nws muaj peev xwm lis siv cov kev cov nyom, tab sis ua ntej ntawd, tus tsim tus tsim tsuas yog soj ntsuam qhov kev ua haujlwm ntawm lub cev, thiab Nws tsis pom zoo tias cov cheeb tsam no yuav hloov thaum tag nrho cov khoom siv txhua yam muab tso ua ke.
Kev tswj lub cev muaj peev xwm ua tau tus qauv ntawm lub SLA qhov hluav taws xob tsis tu ncua, thiab yog tias muaj qhov txawv txav tsis raug, tau txais kev pab tsim nyog. Txij li cov nram qab electromotive quab yuam yog proportional rau kev khiav ceev ntawm lub rotor, nws yuav tsum tau yooj yim siv los txiav txim siab rau sab nrauv load rau cov zis tawm thiab tswj cov khoom tam sim no rau lub tshuab. Lwm qhov chaw uas cov ntaub ntawv los ntawm tus SLA tus pin yog qhov tseem ceeb heev yog thaum lub cev muaj zog mus nkag rau cheeb tsam resonant. Los ntawm kev tsim ib qho kev qhia kom paub qhov xwm txheej sai sai, qhov kev tswj fwm hauv lub cav tau sai tau los ntawm qhov chaw no kom ncav kom muaj kev nyab xeeb tshiab.
Cov paj liab nyob rau sab laug ntawm Daim Duab 1 qhia txog lub ntsiab lus hauv lub cev. Qhov no tej zaum yuav yog vim muaj qhov teeb meem ntawm lub cav, qhov kev siv zaus ntawm kev tsav tsheb ntawm cov kauj ruam ntawm theem, los yog lwm yam khoom thib ob. Cov no yog feem ntau sib txuas ceev zones uas yuav tsum tau zam. Yog hais tias siv IB Semiconductor lub sab nraum qab EMF tshuab, nws tuaj yeem yooj yim mapped nyob rau hauv ib qho teeb meem ntawm feeb. Qhov no yuav pab txo lub siab ntawm lub tshuab electromechanical. Qhov no yog qhov tseem ceeb vim tias qhov kev ntsuas siab tuaj yeem ua rau suab nrov nrov, ua rau lub luag haujlwm tsis zoo, thiab ua rau txo kev cia siab. Qhov tseem ceeb ntawm txoj kev sau cov ntaub ntawv no yog tias qhov txheej txheem xa ntawv yuav tiav tsis tas hloov ntawm lub cev. Qhov tsuas sensor yog lub cav nws tus kheej, yog li ntawd tsis muaj kev kho dua ntxiv yam.
Lub voj voos ntawm sab xis ntawm sab xis 1 qhia tias thaj chaw uas tsav tam sim no tshaj RLC lub sij hawm ntawm qhov system, uas ua rau cov khoom seem ntawm lub cav qoj. Nws yog qhov "txwv tsis pub tshaj" rau qhov kev siv tshuab electromechanical.
Qhov nruab nrab ntawm ob qhov no yog qhov chaw ua hauj lwm hauv lub cev muaj zog. Nws kuj tseem yuav tsum tau sau tseg tias tib daim map kuj tuaj yeem siv los taw qhia cov chaw nyob rau qhov chaw uas lub cav tsis tuaj yeem ua raws li (thiab tsis muaj peev xwm tsim tau EMF). Nyob rau hauv qhov system tswj, qhov teeb meem no tsuas yog tswj tau los ntawm kev teeb tsa yam tsawg kawg nkaus ntawm kev sib tw motor.
Siv cov ntawv qhia cov qauv hauv koj tsim
Thaum twg tus kuas tiav thiab qhov zoo tagnrho ceev profile paub, qhov zoo tshaj plaws SLA nqi yuav raug xaiv. Rau ib qho kev ua haujlwm, nws yuav sawv cev rau qhov taw tes ua haujlwm tshaj plaws. Tsav tsheb tswj zog xws li tam sim no tsav, acceleration, thiab ceev yuav dynamically kho kom tsis txhob muaj teeb meem uas yuav ua kom efficiency, xws li mechanical resonance thiab ntau tsav tam sim no. Qhov zoo ntawm qhov tsis zoo los sis EMF txoj kev zoo dua yog qhov kev tawm tswv yim los ntawm tus sensor tsis yog ib qho yooj yim binary cov ntaub ntawv, tab sis yuav siv tau los nrhiav cov ncauj lus kom ntxaws txog kev tshawb fawb ntawm lub tshuab tsis pub ntxiv qhov nyuaj, cia peb siv Hloov cov kev hloov hauv SLA rau cov sij hawm them rov qab los kom tsis txhob poob cov kauj ruam.
