Model Predictive Control for Open Winding PMSM Based on Optimizing Dead-Zone Effect

Inhalt:
In order to improve the steady-state performance of open winding permanent magnet synchronous motor (OW-PMSM) with common dc bus in conventional single-vector model predictive control (CSMPC), a model predictive control based on optimizing dead-zone effect is put forward. First, dead-zone effect in CSMPC is analysed. Then, the model predictive control based on optimizing dead-zone effect is put forward where the applied time of dead-zone voltage vector (DVV) is variable. Finally, the simulation results verify the effectiveness of the proposed method.
