摘要

To address the challenges associated with medium-voltage (MV) high-power drive systems powered by three-level inverters, including the need for multi-objective optimization to control neutral-point voltage and achieve low switching frequency, as well as the difficulties and complexity of designing weighting factors, this paper proposes a satisfactory optimization sequential FCS-MPC (SO-SMPC) scheme. The current tracking, neutral-point voltage control, and switching frequency are assigned high, medium, and low priorities, respectively, and an optimized solution that satisfies all three control objectives is obtained through a multi-layer cost function. Furthermore, the proposed scheme reduces the computational burden of the enumeration search algorithm by incorporating the deadbeat (DB) control.
