Unified Matrix Polynomial Approach for Operational Modal Analysis
نویسندگان
چکیده
The Unified Matrix Polynomial Approach (UMPA) was developed to understand the basic similarities among various commercially used experimental modal analysis (EMA) algorithms like LSCE, ERA, PTD, PFD etc. It provided a common framework to develop most of these algorithms that have been developed in isolation, thus making it easier to understand and compare them. This paper extends the concept of UMPA to Operational Modal Analysis (OMA) and illustrates methodologies needed in order to make UMPA suitable for cases where the forces exciting the system are not measured.

Using the unified matrix polynomial approach (UMPA) for the development of the stochastic subspace identification (SSI) algorithm
The unified matrix polynomial approach (UMPA) was developed in order to understand and derive various experimental modal analysis algorithms (which have been developed in isolation) using a common mathematical formulation. Various commercially available algorithms – such as the polyreference time domain, least squares complex exponential, and eigensystem realization algorithm etc. – can be expl...
متن کاملA Unified Approach for Design of Lp Polynomial Algorithms
By summarizing Khachiyan's algorithm and Karmarkar's algorithm forlinear program (LP) a unified methodology for the design of polynomial-time algorithms for LP is presented in this paper. A key concept is the so-called extended binary search (EBS) algorithm introduced by the author. It is used as a unified model to analyze the complexities of the existing modem LP algorithms and possibly, help ...
متن کاملOperational Modal Parameter Estimation from Short Time-Data Series
Operational Modal Analysis (OMA) is a technique of extracting modal parameters of a system from output responses only. It is an emerging field in structural dynamics and has been applied to complex structures that are often difficult to analyze using traditional Experimental Modal Analysis (EMA) techniques. Since the input information is unavailable in OMA, the technique makes use of certain as...
متن کاملCombined State Order and Model Order Formulations in the Unified Matrix Polynomial Method (UMPA)
The unified matrix polynomial (coefficient) method (UMPA) has been used by the authors to provide a single, educational framework that encompasses most commercial and research methods used to estimate modal parameters from measured input-output data (normally frequency response functions). In past publications of this methodology, the issue of state order has not clearly been identified in the ...
متن کاملA comparison between modal damping ratios identified by NExT-ERA and frequency domain impact test
In this research, the modal parameters of a beam in free-free condition are extracted by performing different experiments in laboratory. For this purpose, two different techniques are employed. The first methodology is considered as a time domain method in Operational Modal Analysis. While the other one is frequency domain impact hammer test which is categorized as an Experimental Modal Analysi...
