The proper orthogonal decomposition (POD) approach is applied to a linear finite element (FE) model of a squirrel cage induction machine. In order to obtain a reduced model valid on the whole operating range, snapshots are extracted from the simulation of typical tests, such as at the locked rotor and the synchronous speed. Then, the reduced model of the induction machine is used to simulate different operating points with variable rotation speed, and the results are compared to the full FE model to show the effectiveness of the proposed approach.

基于POD的降阶模型在笼型异步电动机线性有限元模型中的应用。

适当的正交分解（POD）方法应用于鼠笼感应电机的线性有限元（FE）模型。为了获得在整个工作范围内有效的简化模型，从典型测试的仿真中提取快照，例如在锁定转子和同步转速下的快照。然后，将感应电机的简化模型用于模拟可变转速下的不同工作点，并将结果与​​完整的有限元模型进行比较，以证明该方法的有效性。
