为了提高电动汽车动力传动系的性能和集成度，研究了一种双三相永磁同步电机(PMSM)驱动，以实现混合储能系统的电源管理。两套电机绕组通过逆变器分别与超级电容器和电池相连。首先，通过建模和矢量图分析，研究了集成系统的运行模式。在此基础上提出了一种新的控制方案，以加强对不平衡绕组功率分配的调节。并讨论了在不平衡功率运行条件下抑制电机谐波电流的方法。最后进行分频协调控制，以获得良好的动态响应和无缝的暂态过程。仿真和实验结果验证了所提出的系统和控制策略的有效性。
To improve the performance and integration of the power train of electric vehicles power, a dual three-phase permanent magnet synchronous machine (PMSM) drive is investigated to achieve hybrid energy storage system power management. Two sets of motor windings are connected with ultracapacitors and a battery, respectively, through the inverters. First, the operation modes of the integrated system are studied by modeling and vector diagram analysis. A new control scheme is then established to enhance the regulation for unbalanced winding power distribution. The approach to suppress the motor harmonics current under the unbalanced power operation is also discussed. Finally, a frequency dividing coordinated control is performed for good dynamic response and seamless transient process. Both simulation and experiment results verify the effectiveness of the proposed system and the control strategy.
