Model  predictive  control  (MPC)  is  a  popular  choice  for  electric drive  applications  due  to  its  ease  of  implementation,  and  fast dynamics.  However,  when  a  two-level  inverter  is  used,  it  can result in large current ripples due to a limited number of voltage vectors. Therefore, this study proposes a method called the five-level virtual voltage vectors based on MPC with discrete space vector pulse width modulation (FLVV-MPC-SVPWM) to improve steady-state  performance  of  the  current  control  for  permanent magnet  synchronous  motors  (PMSMs).  The  proposed  method generates virtual voltage vectors that are equivalent to the ones produced by a 5-level active neutral-point clamped converter (5L-ANPC), resulting in a total of 125 voltage vectors. The proposed FLVV-MPC-SVPWM aims to achieve a steady state performance near to that of the widely-used field-oriented control approach (FOC). The results of FLVV-MPC-SVPWM have near the steady-state performance as  FOC, and guarantee a faster dynamic response.
