N2 - This paper proposes a flux-weakening (FW) control for dual three-phase ermanent magnet synchronous machine (DT-PMSM) based on vector space decomposition (VSD) control, where the output voltage in αβ sub-plane is employed for voltage feedback in the flux-weakening control loop. As the fundamental components are mapped to αβ sub-plane while the 5th and 7th harmonics are projected to harmonic z1z2 sub-plane, the flux-weakening current from this new control in αβ sub-plane is sixth harmonic-free regardless of the 5th and 7th harmonics being resulted from the non-sinusoidal back EMF or inverter non-linearity. The proposed control is compared with the conventional FW feedback control extended for DT-PMSM, where the FW control is applied to the two sets of three-phase windings separately. The experimental results show that the proposed FW control based on VSD is superior to the conventional FW control in terms of reduction in current unbalance and harmonic currents.
