One of the main difficulties in applying modern control theories for designing robust
controllers for linear uncertain plants is the lack of adequate models describing structured …

This paper considers the identifiability of state space models for a system that is expressed
as a linear fractional transformation (LFT): a constant matrix (containing identified …

This report provides a practical and tutorial proof for the existence of linear fractional
representations of multidimensional rational matrix mappings. The existence result is used …

The motivation for this paper is to contribute to a unified approach to modeling, realization,
approximation and analysis for systems with a rich class of uncertainty structures. The …

Les travaux présentés dans ce mémoire s' inscrivent dans le cadre d'un projet de dimension
européenne réalisé en partenariat avec l'Agence Spatiale Européenne et EADS Astrium sur …

A mixed linear parameter-varying (LPV)/μ technique is applied to global control of an air
defense missile. The technique is a direct extension of μ-synthesis that additionally …

First, the LFT modeling framework and the inherent problems are introduced. After the
description of the generic aircraft, the applied LFT modeling procedure is detailed. Then …

The model based design of advanced flight control systems raises many computational
challenges both in developing design adequate models as well as in solving optimization …

This paper presents an overview of system modelling in LFT (Linear Fractional
Transformation) form. An LFT form serves often to replace a bank of linearized models by a …
