Control and Drive Techniques for Multiphase Machines: A Review

由于能够实现低压大功率、高可靠性、高控制灵活度等优点,多相电机在交流传动领域得到了越来越多的应用。本文概述多相电机及其控制驱动技术的国内外发展历史,介绍矢量控制、直接转矩控制、模型预测控制三种典型的多相电机控制方法,对比解耦控制和最优电流控制两种容错控制策略,并归纳目前出现的多相逆变器的各种拓扑结构及其特点,进而对两种PWM调制策略的研究现状进行讨论,最后对当前的多相电机控制驱动技术进行了简要总结和展望。

Multiphase machines are gaining increasing popularity because of their distinct advantages over three-phase alternatives, such as high power at low voltage, high reliability and improved control dimensions. This paper describes the development of multiphase drive techniques at home and abroad, then introduces three control methods including vector control, direct torque control and model predictive control, and compares decoupled fault-tolerant control with optimal fault-tolerant control. Furthermore, the different kinds of multiphase converter topologies are listed, and two kinds of PWM methods are discussed in this paper. Finally, the developing trends of all the above control and drive techniques are summarized.
