Abstract

A holistic approach to machine modeling is essential for realistic drive simulations. Typically, a simulation of the electrical machine behavior and its control is either time consuming or inaccurate. This paper presents a magnetic switched reluctance machine (SRM) model considering material saturation, mutual coupling, asymmetries in excitation and possible asymmetries in geometry. The machine model enables a dynamic motor simulation in combination with control and inverter. This is necessary when considering operation of special fault tolerant SRMs. Furthermore, the unbalanced stator- and rotor tooth forces due to asymmetric excitation during fault operation are calculated. The model can be used with distributed inverters and their respective control structures to effectively design suitable fault tolerant control strategies.
考虑不对称的开关磁阻电机模型,实现动态故障仿真
一个整体的方法来机器建模是必不可少的现实驱动仿真。通常,对电机行为及其控制的模拟要么耗时,要么不准确。本文提出了一种考虑材料饱和、相互耦合、激励不对称性和可能的几何不对称性的开关磁阻电机模型。机器模型使动态电机仿真与控制和逆变器相结合。在考虑特殊容错srm的操作时,这是必要的。此外,还计算了故障运行时由于不对称激励引起的定子和转子的不平衡齿力。该模型可与分布式逆变器及其控制结构相结合,有效地设计出合适的容错控制策略。
