The principle of permanent magnet synchronous motor (PMSM) torque control could be seen as driving the stator flux linkage vector to chase a rotating reference by the voltage vectors. An increase in the magnitude of the stator flux linkage vector limits the ability of the voltage vector to vary the torque angle and the torque. In most control strategies, simultaneously increasing that magnitude and the torque angle slows down the PMSM torque response. In this article, a new method to quicken the PMSM torque rising is proposed. The key idea is to predict an almost static flux linkage vector as the target and find a shortcut consisting of the voltage vector sequence during torque tracking to catch up with the rotating reference rapidly. Then, the torque rising can be accelerated by first shortening the stator flux linkage vector to quickly rotate it and then lengthening it. A set of comparative experimental results are presented to confirm the validity of this method.

直接追逐旋转磁链矢量实现永磁同步电机的快速转矩提升

永磁同步电机 (PMSM) 转矩控制的原理可以看作是驱动定子磁链矢量通过电压矢量追逐旋转参考。定子磁链矢量幅度的增加限制了电压矢量改变扭矩角和扭矩的能力。在大多数控制策略中，同时增加该幅度和扭矩角会减慢 PMSM 扭矩响应。本文提出了一种加快永磁同步电机转矩上升的新方法。关键思想是预测一个几乎静态的磁链矢量作为目标，并在转矩跟踪期间找到由电压矢量序列组成的捷径，以快速赶上旋转参考。然后，可以通过先缩短定子磁链矢量使其快速旋转，然后加长定子磁链矢量来加速转矩上升。提供了一组对比实验结果来证实该方法的有效性。
