Stationary reference frame sensorless vector control based on primary flux linkage and sinusoidal complete tracking current controller for IPMSM

This paper proposes a sensorless vector control method based on Primary flux linkage and sinusoidal current tracking control for Interior permanent magnet synchronous motor. The proposed sensorless vector control can control torque at different speeds. Furthermore, the proposed sensorless vector control method estimates the primary flux linkage vector. At various speeds, it is possible to control the torque without relying on position or speed information.
