dc.description.abstract | We present a framework for constructing structured realizations of linear dynamical systems having transfer functions of the form C̃(∑<sub>k=1</sub><sup>K</sup> h<sub>k</sub>(s)Ã<sub>k</sub>)<sup>-1</sup>B̃ where <i>h<sub>1</sub>, h<sub>2</sub>, ..., h<sub>k</sub></i> are prescribed functions that specify the surmised structure of the model. Our construction is data-driven in the sense that an interpolant is derived entirely from measurements of a transfer function. Our approach extends the Loewner realization framework to more general system structure that includes second-order (and higher) systems as well as systems with internal delays. Numerical examples demonstrate the advantages of this approach. | en |
