2、旨在抑制開關(guān)磁阻電機(jī)轉(zhuǎn)矩脈動(dòng)，針對(duì)這一問題，提出了不同的控制方法抑制它并做了比較。首先分析了開關(guān)磁阻電機(jī)的工作原理，并介紹了電流斬波控制、角度位置控制、電壓控制三種常見的控制方法優(yōu)缺點(diǎn)。然后介紹了目前國(guó)內(nèi)外抑制開關(guān)磁阻電機(jī)轉(zhuǎn)矩脈動(dòng)的方法，結(jié)合本文，重點(diǎn)介紹了轉(zhuǎn)矩分配函數(shù)控制策略及直接轉(zhuǎn)矩控制策略。針對(duì)三相開關(guān)磁阻電機(jī)，本文對(duì)轉(zhuǎn)矩分配函數(shù)的設(shè)計(jì)進(jìn)行了研究。在Matlab仿真平臺(tái)下，對(duì)基于轉(zhuǎn)矩分配函數(shù)法的開關(guān)磁阻調(diào)速電機(jī)驅(qū)動(dòng)系統(tǒng)進(jìn)行了仿真。直接轉(zhuǎn)矩控制的難點(diǎn)是如何選取三相開關(guān)磁阻電機(jī)的6個(gè)有效電壓矢量

3、。Matlab環(huán)境中，搭建了開關(guān)磁阻電機(jī)直接轉(zhuǎn)矩控制的仿真模型，仿真結(jié)果顯示定子磁鏈軌跡為圓形，電機(jī)轉(zhuǎn)矩脈動(dòng)比常規(guī)控制方法小。最后，本文總結(jié)了一下文章的主要研究成果，并且對(duì)課題進(jìn)行了展望，為后面的研究做了鋪墊。關(guān)鍵詞開關(guān)磁阻電機(jī)直接轉(zhuǎn)矩控制轉(zhuǎn)矩分配函數(shù)MatlabI開關(guān)磁阻電機(jī)轉(zhuǎn)矩脈動(dòng)抑制技術(shù)的研究ResearchoncontroltechniqueofswitchreluctancemotortorquerippleAbstractWithlotsofvirtues:solidstructure
