Model Predictive Control for OW-PMSM Based on A Novel Distribution of Reference Voltage Vector

Model predictive current control (MPCC),zero sequence current,common-mode voltage(CMV)

For the common DC bus open-winding permanent magnet synchronous motor (OW-PMSM) system, the presence of zero-sequence current (ZSC) and common-mode voltage (CMV) will bring negative impact on its control effect due to the zero-sequence circuit provided in the system. In order to solve this problem, this paper introduces a novel model predictive current control method based on the redistribution of reference voltage vector, which can effectively suppress the zero-sequence current as well as reduce the common-mode voltage while ensuring good control performance.
