Based on the mathematical model of induction motor , this paper discusses the rotor - field - orientated control principium and the space vector pulse width modulation principle . subsequently the software design of svpwm is put forward 本文在分析感應(yīng)電機(jī)數(shù)學(xué)模型的基礎(chǔ)上,詳細(xì)討論了轉(zhuǎn)子磁場定向矢量控制理論和空間矢量脈寬調(diào)制技術(shù)原理,提出了svpwm的軟件實(shí)現(xiàn)方法。
