Abstract

This paper proposes a new current-regulated switching strategy and a torque pulsation reduction method for a matrix converter PMSM drive system. The current-loop and speed-loop control algorithms of the drive system are implemented by a digital signal processor. By using this new switching strategy, the current harmonics of the system are effectively reduced. In addition, the speed can be adjusted as low as 1 r/min due to the torque pulsation reduction method. Several experimental results are shown to validate the theoretical analysis
