Abstract
A predictive current control in the synchronous reference frame with the back EMF estimation using the previous voltages and currents is proposed. To reduce the torque ripple produced by harmonics in the air gap flux, the q-axis current is compensated using the estimated torque constant. The effectiveness of the proposed control is compared to the conventional control scheme through the simulation.
