高度暴露的永磁材料的开发和更容易部署推动了许多工业应用中永磁同步电机(PMSM)在变速电机中的使用增加。使用 PMSM 驱动器的固有优势包括高扭矩重量比、高功率因数、更快的响应、坚固的结构、易于维护、易于控制和速度和/或位置控制需要准确了解转子轴的位置和速度,以便将相位激励脉冲同步到转子位置。这意味着需要速度和位置传感器,例如连接到电机轴上的编码器和磁性旋转变压器。然而,在大多数应用中,这些传感器存在一些缺点,例如可靠性降低、易受噪声影响、额外的成本和重量以及驱动系统的复杂性增加。无传感器矢量控制对速度/位置传感器的需求,克服了这些挑战。
近年来,研究文献中提出了几种解决方案,重点是PMSM的速度和位置无传感器方法。已经开发了三种基本技术,用于PMSM驱动器的无传感器转子位置估计。
基于反电动势(back-EMF)估计的技术
基于状态观察器和扩展卡尔曼滤波(EKF)的技术
基于空间显著性跟踪的其他技术 - 初始定位
反电动势技术
基于反电动势技术的位置估计根据电压和电流估计磁通和速度,这对低速范围内的定子电阻特别敏感。由于机器的反电动势小和开关器件非线性特性产生的系统噪声,几乎无法检测到机器终端上的实际电压信息。反电动势方法在中高速和高速区域产生良好的位置估计,但在低速区域失败。
