多相绕组结构提供了即使在其定子相中的一个或多个开路的情况下也具有起动和运行能力的感应电机。然而，当在这样的结构不平衡条件下操作时，机器的动态特性将从其平衡操作条件急剧改变。例如，为平衡绕组结构开发的磁场定向控制策略将不再正常工作，并可能导致灾难性的后果。本文提出了一种统一的方法，用于单相开路双三相感应电机的建模和磁场定向控制。该方法利用矢量空间分解的概念，直接建立在不对称绕组结构的基础上，为结构不平衡感应电机的建模和控制提供了一种精确的、物理上直观的工具。
The multiphase winding structure provides an induction machine with capabilities of starting and running even with one or more of its stator phases open-circuited. However, when operated with such a structurally unbalanced condition, the dynamic properties of the machine will change drastically from its balanced operation condition. For example, field-oriented control strategies developed for a balanced winding structure will no longer function properly and could lead to catastrophic consequences. In this paper, a unified approach to the modeling and field-oriented control of dual three phase induction machine with one phase open is presented. Using the concept of vector space decomposition, the proposed technique is established on the basis of the asymmetrical winding structure directly, and thus provides a precise, physically insightful tool to the modeling and control of induction machines with structural unbalance.
