Abstract

The interest in multiphase drives has re-emerged in the last decade, being the dual three-phase induction motor drive one of the most popular options. Predictive control techniques, already implemented in three-phase drives, have been recently adapted to the multiphase case. Schemes proposed so far have restricted the available number of voltage source inverter (VSI) switching vectors but do not impose any constraint on the allowable commutations of these vectors. This paper proposes not to select a subgroup of possible VSI switching vectors, but to constrain the commutations involved in the next sampling period. This procedure allows decreasing the switching period and improving the predictive control performance. The viability and effectiveness of the proposal is verified by simulation.
