采用矢量控制方式的通用變頻器不僅可在調(diào)速范圍上與直流電動(dòng)機(jī)相匹配，而且可以控制異步電動(dòng)機(jī)產(chǎn)生的轉(zhuǎn)矩。由于矢量控制方式所依據(jù)的是準(zhǔn)確的被控異步電動(dòng)機(jī)的參數(shù)，有的通用變頻器在使用時(shí)需要準(zhǔn)確地輸入異步電動(dòng)機(jī)的參數(shù)，有的通用變頻器需要使用速度傳感器和編碼器，并需使用廠商指定的變頻器專用電動(dòng)機(jī)進(jìn)行控制，否則難以達(dá)到理想的控制效果。目前新型矢量控制通用變頻器中已經(jīng)具備異步電動(dòng)機(jī)參數(shù)自動(dòng)辨識、自適應(yīng)功能，帶有這種功能的通用變頻器在驅(qū)動(dòng)異步電動(dòng)機(jī)進(jìn)行正常運(yùn)轉(zhuǎn)之前可以自動(dòng)地對異步電動(dòng)機(jī)的參數(shù)進(jìn)行辨識，并根據(jù)辨識結(jié)果調(diào)整控制算法中的有關(guān)參數(shù)，從而對普通的異步電動(dòng)機(jī)進(jìn)行有效的矢量控制。除了上述的無傳感器矢量控制和轉(zhuǎn)矩矢量控制等，可提高異步電動(dòng)機(jī)轉(zhuǎn)矩控制性能的技術(shù)外，目前的新技術(shù)還包括異步電動(dòng)機(jī)控制常數(shù)的調(diào)節(jié)及與機(jī)械系統(tǒng)匹配的適應(yīng)性控制等，以提高異步電動(dòng)機(jī)應(yīng)用性能的技術(shù)。為了防止異步電動(dòng)機(jī)轉(zhuǎn)速偏差以及在低速區(qū)域獲得較理想的平滑轉(zhuǎn)速，應(yīng)用大規(guī)模集成電路并采用專用數(shù)字式自動(dòng)電壓調(diào)整（AVR）控制技術(shù)的控制方式，已實(shí)用化并取得良好的效果。
