Current vector decoupling control for six-phase PM synchronous motor considering harmonic current

To eliminate undesired 5th and 7th stator harmonic current in six-phase permanent magnet synchronous motor (PMSM) drive system, A current vector decoupling control strategy based on PI controller parallel with vector proportional-integral (PI-VPI) is proposed in this paper, which can control the fundamental and harmonic sub-space separately. an PI-VPI controller used in x-y plane can achieve the zero steady-state error control of both dc and ac components. simulation results verify the effectiveness of the proposed current vector de controller.
