Qhov inductance me me ntawm cov motors ceev ceev yeej ua rau muaj teeb meem ntawm cov ripple loj. Qhov ntxiv tooj liab poob, hlau poob, torque ripple, thiab vibration suab nrov los ntawm cov ripple siab tuaj yeem ua rau cov kev poob ntawm cov motors ceev ceev ntau ntxiv, txo qhov kev ua haujlwm ntawm lub cev muaj zog, thiab electromagnetic cuam tshuam los ntawm cov suab nrov vibration siab tuaj yeem ua rau tus tsav tsheb laus sai dua. Cov teeb meem saum toj no cuam tshuam rau kev ua haujlwm ntawm cov motors ceev ceev, thiab kev tsim kho kom zoo ntawm cov khoom siv hluav taws xob qis yog qhov tseem ceeb rau cov motors ceev ceev. Hauv kev xaus, kev tsim cov motors ceev ceev yuav tsum tau xav txog ntau yam, suav nrog kev sib txuas tam sim no, kev ncua sijhawm ntawm lub cev muaj zog, qhov yuam kev parameter, thiab cov teeb meem kev siv tshuab xws li kev tswj tam sim no ripple. Nws yog ib qho txheej txheem nyuaj heev uas tso cov kev xav tau siab rau cov tswv yim tswj hwm, qhov tseeb ntawm rotor, thiab kev tsim hluav taws xob topology.
2, Txoj Kev Tswj Xyuas rau Lub Tshuab Tsav Tsheb Ceev Ceev
1. Kev Tsim Qauv ntawm Lub Tshuab Tswj Xyuas Kev Kub Ceev
Cov yam ntxwv ntawm kev ua haujlwm siab zaus thiab qhov sib piv qis zaus hauv cov tshuab tsav tsheb ceev ceev, nrog rau kev cuam tshuam ntawm kev sib txuas lub cev muaj zog thiab kev ncua sijhawm rau lub kaw lus, tsis tuaj yeem tsis quav ntsej. Yog li ntawd, xav txog ob qho tseem ceeb saum toj no, kev ua qauv thiab kev txheeb xyuas kev tsim kho dua tshiab ntawm cov tshuab tsav tsheb ceev ceev yog qhov tseem ceeb rau kev txhim kho kev tsav tsheb ntawm cov tshuab tsav tsheb ceev ceev.
2. Kev Tswj Xyuas Kev Sib Cais rau Cov Tsav Tsheb Ceev
Cov thev naus laus zis siv dav tshaj plaws hauv cov tshuab tsav tsheb ua haujlwm siab yog FOC tswj. Txhawm rau teb rau qhov teeb meem loj ntawm kev sib txuas uas tshwm sim los ntawm kev ua haujlwm siab, qhov kev tshawb fawb tseem ceeb tam sim no yog kev tswj hwm kev sib cais. Cov tswv yim tswj hwm kev sib cais uas tam sim no kawm tuaj yeem faib ua cov tswv yim tswj hwm kev sib cais raws li qauv, cov tswv yim tswj hwm kev sib cais raws li kev cuam tshuam kev them nyiaj, thiab cov tswv yim tswj hwm kev sib cais raws li vector regulator. Cov tswv yim tswj hwm kev sib cais raws li qauv feem ntau suav nrog kev sib cais thiab kev sib cais tawm, tab sis cov tswv yim no rhiab heev rau cov yam ntxwv ntawm lub cev muaj zog thiab tuaj yeem ua rau lub cev tsis ruaj khov hauv cov xwm txheej ntawm cov yuam kev loj, thiab tsis tuaj yeem ua tiav kev sib cais tag nrho. Kev ua haujlwm tsis zoo ntawm kev sib cais tsis zoo txwv nws qhov kev siv. Ob txoj kev tswj hwm kev sib cais tom kawg tam sim no yog qhov chaw tshawb fawb kub.
3. Kev Siv Tshuab Them Nyiaj Ncua Sijhawm rau Cov Tshuab Tsav Tsheb Ceev
Kev siv tshuab tswj kev sib cais ua ke tuaj yeem daws tau qhov teeb meem kev sib txuas ntawm cov tshuab tsav tsheb ceev ceev, tab sis qhov txuas qeeb uas tau tsim los ntawm kev ncua tseem muaj, yog li xav tau kev them nyiaj rau kev ncua ntawm lub kaw lus. Tam sim no, muaj ob txoj hauv kev them nyiaj tseem ceeb rau kev ncua ntawm lub kaw lus: cov tswv yim them nyiaj raws li qauv thiab cov tswv yim them nyiaj ywj pheej ntawm tus qauv.
