Predictive control of dual three-phase motor model based on harmonic suppression

Abstract

Abstract The traditional model predicts that the dual-three-phase motor is controlled by 12 synthesized virtual voltage vectors, and the suppression effect of harmonic current is average. In this paper, a harmonic suppression control method is proposed to realize the suppression of harmonic current, and then reduce the harmonic loss. At the same time, the calculation of the control quantity at the next time is carried out, the value function corresponding to each vector is calculated, and the optimal vector is determined by traversal optimization.
