Finite control set-model predictive control (FCS-MPC) is emerging as an attractive alternative for power converters control. In comparison with the classical linear controllers, FCS-MPC needs a shorter control loop cycle time to achieve the same performance. But, the conventional FCS-MPC involves a large amount of calculation. The calculation efforts increase with the number of switching states of the power converter as well as the control objectives, which is a challenge for its application. This paper proposes an effective method to simplify the FCS-MPC and to reduce its calculation efforts for its application in matrix converterfed permanent magnet synchronous motors. The experimental results which verify the good performance of the proposed method are presented.
