Current harmonics suppression of dual three-phase synchronous machines with discrete generalized resonant-extended state observer and deadbeat control

Engineering Science and Technology, an International Journal
The sinusoidal phase current of the dual three-phase (DTP) synchronous machines is subjected to the large stator current harmonics on account of the low impedance, resulting in a decrease in efficiency and severe current distortions.
