NOVEL APPROACH TO MODAL MODEL REDUCTION BY MEANS OF THE BALANCED REALIZATION METHOD PART 1 - THEORY

The paper concerns quality improvement of modal model parameters estimation by means of the application of the Balanced Realization (BR) method to identification and removing spurious poles from stabilization diagrams. The author proposed modification of the classical BR method algorithm by introducing an objective criterion of model reduction. Formulated algorithm was implemented in the Matlab environment and verified for data measured on real structures.
