چکیده
Finite Control-Set Model Predictive Control (FCS-MPC) appears as an interesting alternative to regulate multiphase electric drives, thanks inherent advantages such its capability include new restrictions and fast-transient response. Nevertheless, in industrial applications, FCS-MPC is typically discarded control motors because the absence of a modulation stage produces high harmonic content. In this regard, multi-vectorial approaches are innovative solution improve drive performance taking advantage implicit modulator flexibility (MPC) strategies. This work proposes definition set actions formed by couple adjacent large voltage vectors null vector with adaptative application ratio. The combination two provides minimum x-y current injection whereas reduces active production. Moreover, optimum selection for each permits reducing switching frequency. On other hand, time estimated through analytic function based on operating point. procedure avoids use iterative process define duty cycles, hence significatively decreasing computational burden.
