Introduction

With this toolbox, LFR-objects (for a definition, see below) are created:

This toolbox proposes order reduction and approximation tools for after are realization.

It is also possible to consider nonlinear systems, for example the continuum of linearized models can be modelled as an LFR-object. This problem is addressed considering a simplified missile model.

LFR-objects can be used in particular for µ-analysis.
