Optimal Voltage-Vector-Sequence-Based Model Predictive Control With Minimum Current Harmonic for Low-Switching-Frequency PMSM Drives

This paper proposes an optimal voltage- vector-sequence-based model predictive control (MPC) method for permanent magnet synchronous motor (PMSM) drives that exploits the properties of optimized pulse patterns (OPPs). Specifically, by analyzing OPPs from a space vector perspective, the optimal voltage vector sequence and the corresponding duration are determined in an efficient way, bringing about satisfying steady-state performance. Moreover, the switching pulses are modified in real time to ma
