Abstract: This study presents an investigation of the performance of subspace techniques for modal identification using ambient vibration measurements. Several models and structures characterized by increasing degrees of complexity ...

Abstract: The problem of system identification is an inverse problem of difficult solution. Currently, difficulties lie in the development of algorithms that use measured data from the system to characterize it without significant ...

Abstract: This paper and its companion study constitute a two-part attempt at providing a common framework for some methodologies used in obtaining physical parameters of mechanical systems from identified state space models. In the ...

Abstract: This paper presents various numerical investigations about obtaining physical parameters of second-order mechanical systems using the algorithms that were investigated in detail in the first part of this study. To discuss ...

Abstract: This article briefly presents the theory for a system identification and damage detection algorithm for linear systems, and discusses the effectiveness of such a methodology in the context of a benchmark problem that was ...
