“…The control strategy uses measured speed to generate i d and i q as the reference signal, and it has been noted that the torque ripple factor has been reduced to an acceptable level for full load disturbances by using the digital observer controller strategy. Torque ripple minimization using the input‐output feedback linearization control strategy has been proposed 18 . The control strategy eliminates only some particular harmonic order and does not show effective minimization.…”
