Park变换

Park变换 Park变换的目的是将Clark变换后的αβ坐标系转换成d,q旋转坐标系。d轴方向与转子磁链方向重合,所以d轴也叫直轴。q轴方向与转子磁链方向垂直,所以q轴又叫交轴。 旋转矩阵是什么? ⊿abo: $ob = oa\times \cos(\theta)$ 已知:bc = ad $$ \because \angle pad + \angle pab = 90°\\ \angle oab + \angle pab = 90°\\ \therefore \angle oab = \angle pad\\ \angle aob = \angle apd = \angle \theta $$⊿adp: $ad = ap \times \sin(\theta)$ $$ \because oc = ob + bc \\ \therefore oc = oa \times \cos(\theta) + ap \times \sin(\theta) $$所以向量p到d轴的投影为:$oa \times \cos(\theta) + ap \times \sin(\theta)$ ...
