直接轉(zhuǎn)矩控制(DTC)：
1985年，德國魯爾大學(xué)的DePenbrock教授提出了直接轉(zhuǎn)矩控制變頻技術(shù)。該技術(shù)在很大程度上解決了上述矢量控制的不足，并以新穎的控制思想、簡潔明了的結(jié)構(gòu)、優(yōu)良的動靜態(tài)性能了迅速發(fā)展。目前，該技術(shù)已成功地應(yīng)用在電力機車牽引的大功率交流傳動上。
直接轉(zhuǎn)矩控制直接在定子坐標系下分析交流電動機的數(shù)學(xué)模型，控制電動機的磁鏈和轉(zhuǎn)矩。它不需要將交流電動機等效為直流電動機，因而省去了矢量變換中的許多復(fù)雜計算；它不需要模仿直流電動機的控制，也不需要為解耦而簡化交流電動機的數(shù)學(xué)模型。
