摘要

以六相开绕组永磁同步电机(six-phase open-end winding permanent magnet synchronous motor

SOEW- PMSM)为研究对象，提出一种空间矢量脉宽调制(space vector pulse width modulation，SVPWM)与无差拍预测转矩控制(deadbeat predictive torque control，DPTC)相结合的方法，可在增强转矩跟踪性能的同时，实现谐波电流的高精度抑制。首先，SVPWM-DPTC通过产生频率固定的开关脉冲序列进行电压矢量(voltage vectors，VVs)优选，解决了传统DPTC中参考VVs合成需要大量迭代的问题；然后，为了抑制谐波电流，基于多谐波平面分量抵消的原则，在每个扇区的奇偶扇区边界上各选择3个VVs，并分别计算其在3、5次谐波平面的投影，通过比例关系分配作用时间，可以消除输出电压中的所有3次和5次谐波；最后，通过与传统DPTC、SVPWM的控制性能进行比较，实验结果证明，该文所提控制策略对转矩脉动与谐波电流均有较好的抑制效果。

Abstract

In this paper

a space vector pulse width modulation (SVPWM) combined with a deadbeat predictive torque control (DPTC) method is proposed for the first time

taking the six-phase open-end winding permanent magnet synchronous motor (SOEW-PMSM) as the object of research

which can enhance the torque ripple performance while achieving harmonic current high precision suppression. First

SVPWM-DPTC solves the problem that the synthesis of reference VVs requires a lot of iterations in conventional DPTC by generating a switching pulse sequence with a fixed frequency for voltage vectors (VVs) preference. Then

in order to suppress the harmonic currents

this paper selects three VVs on each of the parity sector boundaries of each sector based on the principle of multi-harmonic plane component cancellation

and calculates their projections on the 3rd and 5th harmonic planes

respectively

and all the 3rd and 5th harmonics in the output voltage can be eliminated by allocating the time of action through proportional relationships. Finally

by comparing the control performance with the traditional DPTC and SVPWM

the experimental results prove that the control strategy proposed in this paper has a better suppression effect on both torque pulsations and harmonic currents.
