In this paper, two FCS-MPC strategies based on deadbeat control are proposed for the five-level OW-PMSM drive at the DC-link voltage ratio of 3:1. The space vector diagram of the OW-PMSM drive is divided into 16 subsectors in each sector and the specific subsector is selected according to the reference voltage vector obtained from deadbeat control. In this way, the traversal calculation burden can be greatly relieved with only 2 or 3 candidate vectors. Besides, in view of different optimization objectives, namely high power quality and low switching frequency, the MPC candidate vector selection of five-level vector distribution is designed based on whether the virtual vectors are considered. Finally, the effectiveness and superiority of the proposed FCS-MPC strategies for five-level OW-PMSM drives are verified through experimental comparisons.

五电平开端绕组 PMSM 驱动器的模型预测控制


本文针对直流母线电压比为 3:1 的五电平 OW-PMSM 驱动提出了两种基于无差拍控制的 FCS-MPC 策略。 OW-PMSM驱动器的空间矢量图被分为每个扇区中的16个子扇区，并且根据无差拍控制获得的参考电压矢量来选择具体的子扇区。这样，只需2或3个候选向量就可以大大减轻遍历计算负担。此外，针对不同的优化目标，即高电能质量和低开关频率，根据是否考虑虚拟向量来设计五级向量分布的MPC候选向量选择。最后，通过实验比较验证了所提出的五级OW-PMSM驱动器FCS-MPC策略的有效性和优越性。
