?它是以三相波形整體生成效果為前提，以逼近電機(jī)氣隙的理想圓形旋轉(zhuǎn)磁場軌跡為目的，一次生成三相調(diào)制波形，以內(nèi)切多邊形逼近圓的方式進(jìn)行控制的。經(jīng)實(shí)踐使用后又有所改進(jìn)，即引入頻率補(bǔ)償，能消除速度控制的誤差；通過反饋估算磁鏈幅值，消除低速時(shí)定子電阻的影響；將輸出電壓、電流閉環(huán)，以提高動(dòng)態(tài)的精度和穩(wěn)定度。但控制電路環(huán)節(jié)較多，且沒有引入轉(zhuǎn)矩的調(diào)節(jié)，所以系統(tǒng)性能沒有得到根本改善。?矢量控制變頻調(diào)速的做法是將異步電動(dòng)機(jī)在三相坐標(biāo)系下的定子電流Ia、Ib、Ic、通過三相－二相變換，等效成兩相靜止坐標(biāo)系下的交流電流Ia1Ib1，再通過按轉(zhuǎn)子磁場定向旋轉(zhuǎn)變換，等效成同步旋轉(zhuǎn)坐標(biāo)系下的直流電流Im1、It1(Im1相當(dāng)于直流電動(dòng)機(jī)的勵(lì)磁電流；It1相當(dāng)于與轉(zhuǎn)矩成正比的電樞電流)，然后模仿直流電動(dòng)機(jī)的控制方法，求得直流電動(dòng)機(jī)的控制量，經(jīng)過相應(yīng)的坐標(biāo)反變換，實(shí)現(xiàn)對異步電動(dòng)機(jī)的控制。其實(shí)質(zhì)是將交流電動(dòng)機(jī)等效為直流電動(dòng)機(jī)，分別對速度，磁場兩個(gè)分量進(jìn)行獨(dú)立控制。通過控制轉(zhuǎn)子磁鏈，然后分解定子電流而獲得轉(zhuǎn)矩和磁場兩個(gè)分量，經(jīng)坐標(biāo)變換，實(shí)現(xiàn)正交或解耦控制。矢量控制方法的提出具有劃時(shí)代的意義。然而在實(shí)際應(yīng)用中，由于轉(zhuǎn)子磁鏈難以準(zhǔn)確觀測，系統(tǒng)特性受電動(dòng)機(jī)參數(shù)的影響較大，且在等效直流電動(dòng)機(jī)控制過程中所用矢量旋轉(zhuǎn)變換較復(fù)雜，使得實(shí)際的控制效果難以達(dá)到理想分析的結(jié)果。1985年，德國魯爾大學(xué)的DePenbrock教授首次提出了直接轉(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、簡潔明了的系統(tǒng)結(jié)構(gòu)、優(yōu)良的動(dòng)靜態(tài)性能得到了迅速發(fā)展。目前，該技術(shù)已成功地應(yīng)用在電力機(jī)車牽引的大功率交流傳動(dòng)上。直接轉(zhuǎn)矩控制直接在定子坐標(biāo)系下分析交流電動(dòng)機(jī)的數(shù)學(xué)模型，控制電動(dòng)機(jī)的磁鏈和轉(zhuǎn)矩。它不需要將交流電動(dòng)機(jī)等效為直流電動(dòng)機(jī)，因而省去了矢量旋轉(zhuǎn)變換中的許多復(fù)雜計(jì)算；它不需要模仿直流電動(dòng)機(jī)的控制，也不需要為解耦而簡化交流電動(dòng)機(jī)的數(shù)學(xué)模型。VVVF變頻、矢量控制變頻、直接轉(zhuǎn)矩控制變頻都是交—直—交變頻中的一種。其共同缺點(diǎn)是輸入功率因數(shù)低，諧波電流大，直流電路需要大的儲能電容，再生能量又不能反饋回電網(wǎng)，即不能進(jìn)行四象限運(yùn)行。為此，矩陣式交—交變頻應(yīng)運(yùn)而生。由于矩陣式交—交變頻省去了中間直流環(huán)節(jié)，從而省去了體積大、價(jià)格貴的電解電容。它能實(shí)現(xiàn)功率因數(shù)為l，輸入電流為正弦且能四象限運(yùn)行，系統(tǒng)的功率密度大。該技術(shù)目前雖尚未成熟，但仍吸引著眾多的學(xué)者深入研究。其實(shí)質(zhì)不是間接的控制電流、磁鏈等量，而是把轉(zhuǎn)矩直接作為被控制量來實(shí)現(xiàn)的。
