This paper presents a modeling framework for permanent magnet linear synchronous motors based on magnetic equivalent circuits. In comparison to the commonly used dq0 model, the proposed modeling approach is able to systematically include magnetic saturation effects and has no restriction to harmonic motor quantities. In contrast to existing work, a differential magnetic equivalent circuit network is used to describe the stator quantities and the complete model is derived using a graph-theoretic approach. Furthermore, the resulting model is calibrated with measurements on a test bench and validated with additional measurement scenarios.

使用等效磁路的永磁直线同步电动机建模

本文提出了一种基于磁等效电路的永磁直线同步电动机的建模框架。与常用的dq0模型相比，所提出的建模方法能够系统地包含磁饱和效应，并且对谐波电动机的数量没有限制。与现有工作相反，使用差分磁等效电路网络描述定子数量，并使用图论方法得出完整模型。此外，在测试台上通过测量对结果模型进行校准，并在其他测量场景下进行验证。
