Title
Modal Analysis By State-Space Approach In Frequency Domain.
Abstract
This paper tests a new procedure to identify the eigenvalue problem matrix 'A' and thus the system's modal parameters, by utilizing the frequency response of the system in state-space. A sample identification test is performed with added random error in order to simulate real measuring conditions. Results indicate that it is slightly difficult to identify the 'A' matrix of an undamped system. The error in that system must be very small for these types of systems to be identified. However, when the identification is repeated several times and then averaged, the identification becomes more accurate.
