General Realization Algorithm for Modal Identification of Linear Dynamic Systems.De Callafon, Raymond A.
Conte, Joel P.
The general realization algorithm (GRA) is developed to identify modal parameters of linear multi-degree-of-freedom dynamic systems subjected to measured (known) arbitrary dynamic loading from known initial conditions. The GRA extends the well known eigensystem realization algorithm (ERA) based on Hankel matrix decomposition by allowing an arbitrary input signal in the realization algorithm. This ... read more
