直(zhi)接轉(zhuan)矩控(kong)(kong)制(zhi)(DTC)方(fang)式1985年，德國魯(lu)爾(er)大學的(de)DePenbrock教授(shou)提出(chu)了(le)直(zhi)接轉(zhuan)矩控(kong)(kong)制(zhi)變(bian)頻技(ji)術。該技(ji)術在很大程度上(shang)解決了(le)上(shang)述矢(shi)量控(kong)(kong)制(zhi)的(de)不(bu)(bu)足(zu)，并(bing)以新穎的(de)控(kong)(kong)制(zhi)思想、簡(jian)(jian)潔明了(le)的(de)系統結構、優良的(de)動(dong)(dong)(dong)靜態性能得到了(le)迅速發(fa)展。該技(ji)術已成功地應用在電(dian)力機(ji)車牽引的(de)大功率交流(liu)傳動(dong)(dong)(dong)上(shang)。 直(zhi)接轉(zhuan)矩控(kong)(kong)制(zhi)直(zhi)接在定子坐標系下分析交流(liu)電(dian)動(dong)(dong)(dong)機(ji)的(de)數學模(mo)型，控(kong)(kong)制(zhi)電(dian)動(dong)(dong)(dong)機(ji)的(de)磁鏈和轉(zhuan)矩。它不(bu)(bu)需(xu)要將交流(liu)電(dian)動(dong)(dong)(dong)機(ji)等效為(wei)直(zhi)流(liu)電(dian)動(dong)(dong)(dong)機(ji)，因而省去了(le)矢(shi)量旋轉(zhuan)變(bian)換中的(de)許多復雜計算；它不(bu)(bu)需(xu)要模(mo)仿直(zhi)流(liu)電(dian)動(dong)(dong)(dong)機(ji)的(de)控(kong)(kong)制(zhi)，也(ye)不(bu)(bu)需(xu)要為(wei)解耦而簡(jian)(jian)化(hua)交流(liu)電(dian)動(dong)(dong)(dong)機(ji)的(de)數學模(mo)型。常州市笑(xiao)天自動(dong)(dong)(dong)化(hua)科技(ji)有(you)限公(gong)司主營匯川MD500變(bian)頻器，若有(you)需(xu)要，歡(huan)迎來電(dian)。匯川MD800變(bian)頻器代理(li)公(gong)司
