矢量变换控制,又称磁场定向控制,是近十多年来在交流传动领域中一个十分引人注目的课题。但是,在研究这种控制方法时,人们往往被其复杂的、形式各异的数学模型所迷惑,不容易看清其实质,也不容易了解这种控制方式和其它控制方式之间的实质区别。本文介绍通过在电机学界流行的座标变换方法及统一电机理论推导出矢量变换控制的数学方程的过程,并对这种控制方式的实质进行解释,从而把这种控制方式和其它控制方式区别开来。
Vector change control, also known as magnetic field orientation control, is a very compelling subject in the field of AC drives in the past decade or so. However, when studying this method of control, people are often fooled by their complex mathematical models of various forms. They are not easy to see and do not easily understand the essential difference between this control method and other control methods . This article introduces the process of vector conversion control mathematical equation through the coordinate transformation method popular in motor science and the unified motor theory and explains the essence of this control method to distinguish this control method from other control methods Come.
