Symbolic techniques for low order LFT-modelling

Kurzfassung

Symbolic preprocessing techniques are very useful to obtain low order LFT-representations for parametric models. In this paper we give an overview about existing preprocessing methods and we present new techniques and enhancements of existing methods. All methods are implemented in the new version 2 of the LFR-toolbox and their capabilities are illustrated by a challenging aircraft parametric uncertainty modelling example.
