The Skew Mu Toolbox.This toolbox was written in
colloboration with Gilles Ferreres. The aim of this freeware is to
provide computational µ and skew µ methods for analysing the
robust stability and performance properties of an uncertain closed
loop, subject to LTI parametric uncertainties, neglected dynamics
and to some extent uncertain time-delays. It could also be
considered as a software complement to the book "A practical approach
to robustness analysis with aeronautical applications"
written by Gilles Ferreres and published in 1999 with Plenum (now
available with Springer).
This toolbox includes basic routines to compute upper and lower bounds of classical but also skew µ, for both complex and real uncertainties. Several types of algorithms (exponential-time and polynomial-time) are made available. Unlike most other available robustness analysis tools, this toolbox also contains fully automated procedures which allows a non specialist to obtain guaranteed stability or performance robustness margins. Finally, different realistic engineering applications are included (missile, rigid and flexible aircraft, telescope mock-up), which illustrates the efficiency and the reliability of the proposed tools.
In this last version (version 3.0) of the Toolbox, specific routines have been added to handle the case of highly repeated parametric uncertainties with numerous states. The main routine of this toolbox, upgraded by Jean-Marc Biannic in 2005 is called mu_margin. The algorithm is described in the paper below:

Note that this Toolbox is no longer maintained and has been deeply revised with Clément Roos. The most up-to-date LTI robustness analysis tools are now available with the SMART Library from the SMAC Toolbox.
AWAST
The Anti-Windup Analysis & Synthesis ToolboxThis Toolbox contains a set of
user-friendly routines to perform stability and performance
analysis and design for anti-windup systems. The main routines are
based on the implementation of recent analysis and synthesis
results dedicated to saturated systems:
- J-M. Biannic, C. Roos and S. Tarbouriech. A practical method for fixed-order anti-windup design. In IFAC Symposium on Nonlinear Control Systems, Pretoria, August 2007.
- C. Roos and J-M. Biannic. A convex characterization of dynamically-constrained anti-windup controllers. To appear in Automatica, 2008.

LFRT-SLK
A Simulink interface for the LFR ToolboxThis package is an additional
module to the last version of LFRT Toolbox (version 2.0) which
should then be downloaded first from J-M. Biannic's homepage. This
module contains specific libraries and tools which permit very
easily to build and simulate interconnected LFR objects. The case
of high-order LFRs has received a particular attention.
SMAC
Systems Modelling
Analysis and Control ToolsThis new package is under active
development by a team of 12 research scientists from ONERA/DCSD.
The central objective is to collect and unify various toolboxes in
the field of Automatic Control (Modeling, Analysis,Control).
Coordinated by Jean-Marc Biannic, this project has started in 2012 and is expected to finish in 2015 with a Workshop.
See the specific project page hosted by ONERA for further details and links where limited versions of the tools can be downloaded for evaluation.
