This article proposes a torque enhancement strategy for asymmetrical six phase PMSMs First specific fifth and seventh harmonic currents are injected into the harmonic subspace and reference current benchmarks are set to achieve the desired torque enhancement Then the influence of harmonic plane back electromotive force on the response current is studied and the deadbeat harmonic predictive current control DHPCC equation considering lumped disturbance is derived Furthermore an extended state observer ESO is considered to improve control performance of the proposed strategy Finally the experimental results demonstrate the superiority and effectiveness of the proposed scheme
