In this paper, active
damping control based virtual positive impedance for a PMSM driver is proposed.
The proposed model is assumed to achieve the better motor current with a better
harmonic response. 6 switches can be employed in the design of the driver to
obtain high performance with a simultaneous reduction in the motor current
harmonics and thus the torque ripple of PMSM. However, the reduction of input
current harmonics is very important to operate the PMSM with less cogging
torque. The proposed concept offers a significant decreasing in harmonics.
Thus, the effect of VPI on the cogging torque can be understood. The inverter
with a Field Oriented Control (FOC) method operates in 3-phase and 20 kHz
switching frequency. The PMSM motor is fed by the inverter. The VPI based
active damping control for the motor drive is discussed to confirm the
performance of the proposed method. The simulation results based on MATLAB are
provided to validate the proposed control strategy.
