This article investigates the nonlinear behavior of the conventional voltage feedback flux-weakening control, i.e., the voltage magnitude feedback control on the nonsalient permanent magnet synchronous machine, and proposes an adaptive control parameter tuning method for the voltage feedback controller. Due to less voltage margin in the flux-weakening region, the current dynamic performance is degraded. This issue is more serious when the system operates in the overmodulation region and could affect the system's stability. Based on the designed voltage feedback controller, the system performance in the flux-weakening and overmodulation regions is further improved by utilizing the current and voltage reference modifiers. Consequently, the system can operate well in both linear and overmodulation regions with the specified scaling factor, which is beneficial to general-purpose applications. The viability of the proposed method is demonstrated by the experimental results.

非凸极永磁同步电机上的自适应电压反馈控制器

本文研究了传统电压反馈弱磁控制的非线性行为,即非凸极永磁同步电机的电压幅值反馈控制,并提出了一种电压反馈控制器的自适应控制参数整定方法。由于弱磁区的电压裕度较小,电流动态性能会降低。当系统工作在过调制区域时,这个问题更为严重,可能会影响系统的稳定性。在设计的电压反馈控制器的基础上,利用电流和电压参考调节器进一步提高了弱磁和过调制区域的系统性能。因此,系统可以在具有指定比例因子的线性和过调制区域中良好运行,这有利于通用应用。实验结果证明了所提出方法的可行性。
