Loewner framework

WitrynaThe method under consideration is the Loewner framework, an established data-driven approach that requires samples of input–output mappings. The latter are known as generalized transfer functions, which are appropriately defined for both bilinear and quadratic-bilinear systems. We show connections between these mappings as well as … WitrynaAbstract. The Loewner framework for model reduction is extended to the class of bilinear systems. The main advantage of this framework over existing ones is that the …

Witryna2 Toward a certi ed greedy Loewner framework with minimal sampling (MRI) [7]. In such methods, one leverages a priori knowledge on the structure of the problem, namely, the rational dependence of the transfer function H(z) on the frequency z2C. For this reason, a rational function is introduced as ansatz for the surrogate model.
