비비례감쇠 시스템의 고유치해석에 필요한 누락고유치 검사기법

Abstract

This paper introduces the two recently developed checking techniques for missed eigenvalues of nonproportionally damped system. The first technique is based on the argument principle. On the other hand, the second one is based on Rombout's algorithm and Gleyse's theorem, which has been known as the effective and well-proven method. In the paper, the main features of the two techniques are explained and their effectiveness is also investigated by considering a numerical example.
