Consistency analysis of Kalman Filter for Modal Analysis of Structures

In this paper, consistency analysis of Kalman filter for modal analysis of structural systems is made. As a future work, A fundamental modal analysis algorithm, eigensystem realization algorithm(ERA) will be used with Kalman filters together to make a modal parameter estimation for a structural system. By applying ERA to the impulse response measurements taken from the structure, a state-space representation will be written. Kalman filter will be used as a state estimator in this study and it will have a critical role on minimizing the measurement noise. Before using Kalman filter with ERA, a consistency analysis of Kalman filter is made for artificial impulse response data of the structural system.
