Paper

Generally, standard direct torque control (DTC) does not require fine current responses from the current controller because the torque and flux of a DTC-based drive are controlled by a closed-loop system without current loops. It is often difficult for the standard DTC to achieve the desired current regulation and fine harmonic current disturbance suppression performancew. In order to overcome these problems, this paper proposes a new stationary reference frame position sensorless control system based on stator flux linkage estimation, and a new sinusoidal current tracking controller. In this paper, the current control performance of IPMSMs using the proposed sinusoidal current tracking controller is evaluated through numerical simulation and experiments. Finally, using the proposed sinusoidal current tracking controller, the effectiveness of the proposed stationary reference frame position sensorless control system with the stator flux control method is confirmed through experimental results.
