本文介绍一种模态分析的迭代矩阵法。它使用矩阵变换法作为模式识别的主要工具，并通过利用成本函数的概念来增加它，以减少识别大型系统模式所需的信号数量。该方法在本文中被测试为各种大型综合电网，与成本函数被报告来衡量精度。还考虑了灵敏度分析，显示了这种新方法在调整两个主要基于用户的输入时的行为;迭代次数和SVD阈值。
This paper introduces a modal analysis approach termed as the Iterative Matrix Pencil method. It uses the Matrix Pencil Method as the primary tool for mode identification, and adds to it by utilizing the concept of a cost function in order to reduce the number of signals needed to identify the modes for a large system. The method is tested for a variety of large synthetic power grids in this paper, with the cost function being reported to measure accuracy. A sensitivity analysis is also considered, showing how this new method behaves when adjusting the two primary user-based inputs; the number of iterations, and the SVD threshold.
