Abstract This paper presents a frequency-domain model of the symmetrical dual three-phase permanent magnet synchronous machine (PMSM) in two working modes. Compared with traditional time-domain model, the presented frequency-domain model has simple expression and can be easily used in control system design and compensation. Furthermore, a frequency-model-based field oriented control (FOC) scheme for this machine is proposed. In this control scheme, parameters of proportional-integral (PI) controllers are analytically designed which can flexibly adjust the steady and dynamic performance of the entire closed-loop system. Moreover, this control strategy allows the drive system to bumpless switch between two operating modes without stopping. Finally, the developed control scheme was verified via simulations and experiments.

对称双三相永磁同步电机两种工作模式的建模与无扰动开关控制

摘要 本文提出了对称双三相永磁同步电机（PMSM）在两种工作模式下的频域模型。与传统的时域模型相比，所提出的频域模型表达简单，易于用于控制系统设计和补偿。此外，还为该机器提出了一种基于频率模型的磁场定向控制（FOC）方案。该控制方案对比例积分(PI)控制器的参数进行了解析设计，可以灵活调节整个闭环系统的稳态和动态性能。此外，这种控制策略允许驱动系统在两种运行模式之间无干扰地切换而不会停止。最后，通过仿真和实验验证了所开发的控制方案。
