Recently, the interest in model predictive control (MPC) and dual three-phase drives has been growing rapidly. Due to the high redundancy of voltage vector in the system composed of dual three-phase permanent magnetic synchronous motor (PMSM) and six-phase inverter, the computational complexity andcurrent harmonics of MPC are high. In addition, the zero vector has been used by traditional MPC, which will cause higher common-mode voltage. In this paper, a novel MPC method with twice predictions and synthetic vectors is proposed which can not only suppress common-mode voltage, but also reduce computational complexity and current harmonics. The mathematical model of a dual three-phase PMSM are verified by the experimental results under the common-mode voltage suppression.

双三相永磁同步电动机带共模电压抑制的模型预测控制方法

最近，人们对模型预测控制（MPC）和双三相驱动器的兴趣迅速增长。由于双三相永磁同步电动机（PMSM）和六相逆变器组成的系统中电压矢量的高冗余性，MPC的计算复杂度和电流谐波都很高。此外，传统MPC已使用零矢量，这将导致更高的共模电压。本文提出了一种具有两次预测和合成矢量的MPC方法，该方法不仅可以抑制共模电压，而且可以降低计算复杂度和电流谐波。在共模电压抑制下的实验结果验证了双三相PMSM的数学模型。
