A Predictive Torque Control Method for Dual Three-Phase Permanent Magnet Synchronous Motor Without Weighting Factor

In order to solve the problem of difficult design weighting factor for model predictive torque control (MPTC) dual three-phase permanent magnet synchronous motor (DT-PMSM), this paper proposes a MPTC strategy without factor. Firstly, virtual voltage vector (V 3 ) is introduced reduce harmonic currents. Secondly, an approximate alternative principle predicted current proposed, which simplifies dual-vector prediction and decreases complexity model. The set at ( $k+1$ )th selected by judging change in position stator flux, reduces number candidate vectors. Thirdly, cost function according system state two adjacent moments. separates electromagnetic eliminates Decreasing model, reducing vectors, combination methods can significantly computational burden CPU. Finally, experiments verify effectiveness proposed method. results show that method greatly calculation under performance does not much.
