Predictive current control for permanent magnet synchronous motor based on internal model control observer [PDF]
Archives of Electrical Engineering, 2022 The model predictive current control (MPCC) of the permanent magnet synchronous motor (PMSM) is highly dependent on motor parameters, and a parameter mismatch will cause the system performance degradation. Therefore, a strategy based on an internal model

Analysis of the Saliency Ratio Effect on the Output Torque and the System Efficiency in IPM Drives
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2021 Permanent magnet synchronous motors (PMSM) can be classified into two groups based on the rotor saliency structure as surface mounted permanent magnet synchronous motors (SPM) and interior mounted permanent magnet synchronous motors (IPM). Saliency ratio
