In this paper

a space vector pulse width modulation (SVPWM) combined with a deadbeat predictive torque control (DPTC) method is proposed for the first time

taking the six-phase open-end winding permanent magnet synchronous motor (SOEW-PMSM) as the object of research

which can enhance the torque ripple performance while achieving harmonic current high precision suppression. First

SVPWM-DPTC solves the problem that the synthesis of reference VVs requires a lot of iterations in conventional DPTC by generating a switching pulse sequence with a fixed frequency for voltage vectors (VVs) preference. Then

in order to suppress the harmonic currents

this paper selects three VVs on each of the parity sector boundaries of each sector based on the principle of multi-harmonic plane component cancellation

and calculates their projections on the 3rd and 5th harmonic planes

respectively

and all the 3rd and 5th harmonics in the output voltage can be eliminated by allocating the time of action through proportional relationships. Finally

by comparing the control performance with the traditional DPTC and SVPWM

the experimental results prove that the control strategy proposed in this paper has a better suppression effect on both torque pulsations and harmonic currents.
