A novel flux model and decoupling control on maximum torque control frame for IPMSM position seneorless vector control

This paper proposes a novel flux model for position sensorless control of Interior Permanent Magnet Synchronous Motors (IPMSMs), which can approximately estimate maximum torque control frame. The proposed model can directly estimate the maximum torque control (MTC) frame robustly to magnetic saturation. In addition, this paper proposes the decoupling control method on MTC frame based on the proposed flux model. Finally, some experimental results demonstrate the effectiveness of this proposed method.
