摘　　要：双三相感应电机的绕组开路后,运用传统的旋转坐标变换,不能实现转子磁场定向矢量控制。本文推导出不对称绕组结构的解耦旋转坐标变换,并提出了一种基于不对称绕组结构的转子磁场定向矢量控制新颖策略,运用PI调节器,使得定子侧谐波电流最小化,降低定子侧谐波损耗。在MATLAB MATLAB/Simulink仿真软件下,建立相应的仿真模型,仿真结果验证本文所提出控制策略的正确性和有效性。A vector control scheme based on the rotor field orientation is not adapt for Dual Three-phase Induction Motor with one phase stator windings opened by traditional rotating coordinated transformation. The time decoupting transformation matrix is deduced in this paper and a novel vector control scheme is proposed based on rotor field orientation when the Dual Three-phase Induction Motor appears asymmetrical stator phase winding structures, the application of PI controller minimizes the harmonic current and reduces harmonic loss on the stator side. The simulation model of Dual Three induction machine under fault condition is established using MATLAB simulation software, the simulation results verify the correctness and effectiveness of the control scheme.
