摘要：隨著現(xiàn)代工業(yè)的迅速發(fā)展，多電機系統(tǒng)在機械制造以及自動化控制等領(lǐng)域得到了廣泛的應(yīng)用。多電機系統(tǒng)的復(fù)雜性需要高效且可靠的控制方法來實現(xiàn)其穩(wěn)定運行。因此，本文提出了一種基于dSPACE的多電機系統(tǒng)反步控制方法，針對多電機系統(tǒng)具備多輸入、多輸出的特點，采用了反步控制思路。在建立多電機系統(tǒng)的數(shù)學(xué)模型的基礎(chǔ)上，將反步控制進行了分析和優(yōu)化，并基于dSPACE平臺實現(xiàn)了多電機系統(tǒng)的控制。仿真結(jié)果表明，本文的多電機系統(tǒng)反步控制方法能夠有效控制多電機系統(tǒng)的轉(zhuǎn)速、轉(zhuǎn)矩和位置等運動狀態(tài)，實現(xiàn)了多電機系統(tǒng)的高效穩(wěn)定運行。
