矢量控制（Field oriented control, FOC）通过磁场定向将定子电流分解成励磁分量和转矩分量（ 实现对电磁转矩和转子磁链的解耦 ），然后采用比例积分（proportional integral, PI）调节器在同步旋转坐标系上对其进行分别调节，利用空间矢量调制（Space vector modulation, SVM）等脉宽调制策略合成参考电压矢量。

经过d-q 变换后的控制系统各变量均表示为旋转坐标系下的形式，此时，电机的电磁转矩可以通过控制定子电流q 轴分量来实现，而定子电流d轴分量则与感应电机的磁链幅值有关，d-q 坐标系下的电机模型对之上的关系描述如下（d-q也称为M-T）。

2.1.3 FOC系统仿真搭建及各模块介绍

异步电机矢量控制主要包括速度环、电流环、转矩环、磁链估计、坐标变换和空间电压矢量脉宽调制（SVM）模块。接下来将一一介绍各个模块的工作原理和仿真模型搭建的过程，并结合模块输出的波形进行讨论是否有实现方法。特别是电压重构、转子磁链的估计方法，包括电压型磁链观测器、电流型磁链观测器、混合模型磁链观测器、全阶磁链观测器和 滑模磁链观测器 （ 可以学习一下 ），再讨论比较一下各种脉宽调制的优缺点。
