九相电机驱动中的直接转矩与预测控制策略：基于虚拟电压矢量

One of the main distinctive features of multiphase machines is the appearance of new degrees of freedom (x-y voltages/currents) that do not exist in their three-phase counterparts. As a direct consequence, control approaches that apply a single switching state during the sampling period cannot achieve zero average x-y voltage production. In direct torque control (DTC) this implies that x-y current...
