Abstract

In this paper, to eliminate the weighting factor and suppress the zero-sequence component in conventional model predictive torque control (MPTC), a model predictive full-torque control method (MPFTC) without weighting factor is proposed in the open-winding permanent magnet synchronous motor (OW-PMSM) system with a common dc bus. This method can not only unify the control objectives into the same dimension, but also can effectively suppress the influence of zero-sequence current on the system. Finally, the feasibility of the proposed method is verified by simulation results.
