Abstract

General anesthesia consists in the control of the anesthetic and analgesic states of the patient by adjusting the perfusion of hypnotic and/or analgesic drugs based on clinical indicators. This is an old problem but yet challenging due to numerous phenomena to be considered, such as patient variability, multivariable characteristics, positivity constraints, influence of the hypnotic agent, measurement access, actuator limitation, and so on. It partly explains that, until now, clinical practice remains in open-loop, manually control by the anesthesiologist.

This presentation revisits the control problem of the anesthetic state of a patient under the framework of saturated systems. It pays attention to various phenomena as above described to propose some desgin strategies based on the Lyapunov framework and expressed as LMI-based optimization problems.

Biography

Isabelle Queinnec is currently CNRS researcher at LAAS-CNRS, Toulouse University. 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 limited information, with particular interest in applications on aeronautical systems, robotic, electronic, health, biochemical and environmental processes. She has been serving as member of the IFAC technical committees on "Biosystems and Bioprocesses" and on "Modelling and Control of Environmental Systems", respectively from 2002 and 2005 and of the IEEE CSS-CEB from 2013. She is currently AE for IET Control Theory and Applications and for the IFAC Journal NAHS (Nonlinear Analysis: Hybrid systems). She is co-author of a book on saturated systems and of more than 50 journal papers, both in control theory and in process engineering.
