A Combined State-Space Identification Algorithm Applied to Data From a Modal Analysis Experiment on a Separation System

Abstract [en]

This paper discusses identification of state-space models from impulse response or initial value experiments. Kung's geometrical realization algorithm is combined with classical nonlinear parametric optimization to improve the quality of the estimated state-space model. These ideas are applied on real data originating from a modal analysis experiment on a separation system. The results indicate that the parametric optimization step increases the model quality significantly compared with the initial model the realization algorithm provides.
