摘要

本文采用特征系统实现算法（ERA）对薄膜天线结构模态参数的在轨辨识进行研究。首先对一种薄膜天线的结构形式进行简介，然后给出了ERA方法的基本原理，最后将ERA方法应用于薄膜天线结构的固有频率和模态的辨识。仿真结果显示，ERA方法可以有效地辨识出薄膜天线结构的低阶固有频率和模态。

Abstract

The eigensystem realization algorithm (ERA) was used to identify the modal parameters of a membrane antenna system. The configuration of the membrane system and then the basic theory of ERA were introduced. The modal parameters of a flexible beam and the membrane antenna system were identified by the ERA. The simulation results indicate that the ERA is effective to identify the lowerorder natural frequencies and modal shapes of the membrane antenna system.
