Alternative FCS-MPC concepts for cascade free motor speed control

This paper provides alternative FCS-MPC algorithms for cascade-free motor speed control and compares with conventional FCS-MPC. The proposed algorithms uses the concept of virtual vectors combined with a modulation to reduce the ripple caused by conventional FCS-MPC. The difference in the proposed algorithms is related with the search of the virtual vectors in order to reduce computational cost, memory use or processing. Simulation results are provide showing the benefits of the proposed algorithms.
