The IFAC Symposium NOLCOS will be held in Toulouse on September 4th‐6th 2013

Our book on Stability and Stabilization of Linear Systems with Saturating Actuators, coauthored with Sophie Tarbouriech, Germain Garcia and João-Manoel Gomes da Silva Jr has been published
(Springer, 2011).

NEW:The software SATAW-Tool, which gathers multiple theoretical results regarding the presence of saturation elements in the control loop, including analysis and design of controllers and of anti-windup controllers, is now available.

Last update: March, 2013

Research projects



Isabelle Queinnec is currently CNRS researcher at LAAS-CNRS, Université de Toulouse. She received her PhD degree and HDR degree in automatic control in 1990 and 2000, respectively, from University Paul Sabatier, Toulouse. Her current research interests include constrained control and robust control of processes, with particular interest in applications on aeronautical systems, biochemical and environmental processes. She serves as member of the IFAC technical committees on "Biosystems and Bioprocesses" and on "Modelling and Control of Environmental Systems", respectively from 2002 and 2005.

My main research interests include

Publications The full list of my publications is available on the  publication web base of the LAAS ou directly here. Less often updated, but definitively more readable, you can access the pdf publication list that I transmit to CNRS every two years.
The selection by themes only considers a partial list of my publication, but presented by research subjects. The pdf version of the papers are sometimes given, and the publications may appear several times in the list if required by their subject.

SATAW-Tool (SATuration AWare Tool) is intended to gather multiple theoretical results regarding the presence of saturation elements in the control loop. Simple functions for manipulating saturation elements in the control loop are provided, which build LMI optimization problems allowing analysis and design of controllers, including anti-windup controllers.  The goal is not a commercial product but a platform for academic cooperative exchanges and possible demonstrations for small size application examples.

More details and the complete package are available here.
