Complex space vectors have for decades proven their usefulness for modeling, analysis, and control design in electric power engineering. One fundamental benefit is that they allow two variables—the d and q components of the vector—to be expressed in a single-input–single-output (SISO) notation. Symmetric three-phase systems and dynamic elements can be modeled using complex-coefficient transfer functions. Various extensions, primarily the corresponding two-row real space vectors and two-by-two transfer function matrices—giving a multi-input–multi-output (MIMO) model—allow asymmetric systems and elements to be modeled as well.

客座社论：复矢量理论及其在电力电子系统中的应用专题


几十年来，复杂空间矢量已经证明了其在电力工程建模、分析和控制设计中的有用性。一个基本好处是它们允许两个变量（向量的 d 和 q 分量）以单输入单输出 (SISO) 表示法表示。对称三相系统和动态元件可以使用复系数传递函数进行建模。各种扩展，主要是相应的两行实空间向量和两乘二传递函数矩阵（给出多输入多输出（MIMO）模型）也允许对不对称系统和元件进行建模。
