In this article, two finite control-set MPC (FCS-MPC) strategies based on deadbeat control are proposed for the five-level open-end winding PMSM (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 two or three candidate vectors. Besides, in view of different optimization objectives, namely, high power quality and low switching frequency, the model predictive control (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.
