Outline of Final Research Achievements

This study proposes a novel mathematical model of maximum torque per ampere (MTPA) control for direct torque control (DTC) of permanent-magnet synchronous motors (PMSMs) in the stator flux linkage synchronous (M-T) frame. Consideration of the magnetic saturation and cross-coupling effects in PMSMs requires significant complexity in most of the mathematical models using the rotor synchronous (d-q) frame. In the M-T frame, the mathematical model for MTPA control requires only three parameters that can be determined from only three measured points. The validity of the proposed model was confirmed by both simulation and experimental results. The proposed model can achieve high-efficiency operation in DTC-based PMSM drive system.
