Abstract： To mitigate voltage and stator current errrs induced by dead-time in model predictive control， an optimized model predictive current control （MPCC）method based on the dead-time voltage vector （DTVVMPCC）was proposed for permanent magnet synchronous motor（PMSM）.Firstly，the impact of dead-time on MPCC and the formation mechanism of dead-time voltage vector（DTVV）were analyzed. Secondly， DTVV was categorized into beneficial and non-beneficial types according to its effcts on MPCC performance，with the advantages of beneficial DTVVelucidated.Finally，dead-time duration was optimized. Simulation results demonstrated DTVV-MPCC’s superior current control performance over conventional MPCC.
