摘要: 针对传统永磁同步电机有限控制集模型预测转矩控制( FCS-MPTC) 中的电流波动较大,提出了一种基于虚拟电压矢量的永磁同步电机模型预测转矩控制( VFCS-MPTC) ,该策略扩展了候选电压矢量控制集。 与传统的FCS-MPTC 相比,VFCS-MPTC 在保持恒定开关频率的同时,较大降低了转矩纹波和电流谐波。 采用了一种新的电压矢量优化选取策略,将候选电压矢量的数量从 38 个减少到 9 个,VFCS-MPTC 在不影响控制性能的情况下显著降低了计算负担。 通过仿真对比验证了 VFCS-MPTC 的有效性。

Abstract: In view of the large current fluctuations in the traditional permanent magnet synchronous motor finite control set model predictive torque control ( FCS-MPTC) , a finite control set model predictive torque control method based on virtual voltage vector ( VFCS-MPTC) was proposed. which expanded the set of candidate voltage vector controls. Compared with conventional FCS-MPTC, VFCS-MPTC reduced torque ripple and current harmonics while maintaining a constant
switching frequency. A new voltage vector optimization selection strategy was adopted to reduce the number of candidate voltage vectors from 38 to 9. The proposed VFCS-MPTC reduced the computational burden without affecting the control performance. The effectiveness of VFCS-MPTC was verified through simulation comparison.
