Lub ntsiab lus tseem ceeb ib: Ua raws li lub hauv paus ntsiab lus ntawmqhov sib piv U/f tas liHauv qab qhov ceev pib, qhov sib nqus flux hauv qhov sib txawv ntawm huab cua ntawm lub cev muaj zog yog ncaj qha rau qhovstator voltage thiab zausQhov ruaj khov ntawm qhov sib piv ntawm qhov hluav taws xob thiab zaus (U/f) ncaj qha txiav txim siab seb qhov sib nqus flux puas ruaj khov. Hauv kev tswj hwm, qhov hluav taws xob thiab zaus yuav tsum tau kho tib lub sijhawm kom nruj me ntsis tswj qhov sib piv U/f tsis hloov pauv, zam kev hloov pauv ntawm lub zog los ntawm qhov sib nqus flux saturation lossis tsis txaus. Tsis tas li ntawd, rau cov cav asynchronous, nws yog qhov tsim nyog los them rau qhov poob hluav taws xob stator kom tiv thaiv qhov cuam tshuam ntawm qhov poob hluav taws xob hauv qhov ceev qis rau qhov tseeb ntawm lub zog thiab txhim kho kev ntseeg tau ntawm kev ua haujlwm ceev qis.
Lub Ntsiab Lus Tseem Ceeb Thib Ob: Kev Tswj Xyuas Kom Tseeb ntawm Cov Cheebtsam Tam Sim No. Los ntawm kev siv lub vector tswj architecture, cov tam sim no peb-theem ntawm lub stator raug hloov mus rau hauv cov khoom sib koom ua ke dq. Cov tam sim no q-axis ncaj qha sib raug raulub zog tso zisthiab yuav tsum tau ruaj khov ntawm tus nqi teem tseg los ntawmkev tswj hwm kaw-voj. Lub zog tam sim no ntawm d-axis tswj hwm qhov kev txhawb nqa tas li kom ntseeg tau tias qhov ruaj khov ntawm cov hlau nplaum sib nqus. Tib lub sijhawm, cov kev txwv tam sim no tau teeb tsa los tswj cov kev hloov pauv tam sim ntawd thiab cov xwm txheej pib, zam kev hlawv ntawm cov khoom siv hluav taws xob vim muaj cov hluav taws xob cuam tshuam thiab ua kom muaj cov zis torque du thiab tsis muaj kev co.
Lub Ntsiab Lus Tseem Ceeb Thib Peb: Kev Them Nyiaj Rau Kev Cuam Tshuam Zoo thiab Kev Hloov Kho Rau Cov Xwm Txheej Ua Haujlwm. Kev saib xyuas lub sijhawm tiag tiag ntawm cov kev ntsuas xws li qhov ceev, qhov hnyav, thiab qhov kub thiab txias tau ua tiav. Thaum qhov hnyav hloov pauv tam sim ntawd, qhov voltage thiab tam sim no piv tau hloov kho sai sai los them rau qhov cuam tshuam ntawm kev cuam tshuam rau lub zog torque. Rau qhov kev hloov pauv parameter uas tshwm sim los ntawm qhov kub thiab txias nce, lub tshuab calibration dynamic tau muab los kho qhov sib txawv ntawm kev tiv thaiv thiab inductance. Lub logic pib tau ua kom zoo dua, thiab txoj kev pib mos tau siv los txo qhov kev poob siab torque, ua tiav kev pib ua haujlwm zoo hauv cov xwm txheej hnyav thiab ua kom ntseeg tau tias qhov tseeb thiab kev ruaj khov ntawm kev tswj hwm lub zog torque tas li.
