In this presentation, we propose an extremum-seeking control framework to solve dynamic-optimization problems in finite dimensional nonlinear systems. The extremum-seeking controller design technique leads to
closed-loop systems that can stabilize nonlinear control systems to orbits
that maximize a functional of interest. The problem is posed as a real-time optimal trajectory generation problem in which the optimal orbit is
computed using an extremum-seeking approach. The control algorithm
provides simultaneous tracking of the optimal orbit. A drug delivery system is considered to demonstrate the application of the technique. The
issue of real-time dynamic optimization has also been of concern in the application of model predictive control. In this talk, we will also present an
application of the extremum-seeking technique to solve general nonlinear
model predictive control problems.
Martin Guay received his Ph.D. in Chemical Engineering at Queen’s University in 1996. From 1995 to 1997, he was a research scientist in Research and Development Center at Dupont Canada Inc. In 1997, he joined
the Department of Chemical and Materials Engineering at the University
of Alberta where he was Assistant Professor until 1999. He then joined
the Department of Chemical Engineering at Queen’s University where he is
Associate Professor. He is currently on leave at CESAME at l’ Université
Catholique de Louvain in Louvain-la-Neuve, Belgium. In 2004, he received
the Premier Research Excellence Award from the Government of Ontario.
His research interests are in the area nonlinear control theory, process
control, bioprocess control and manufacturing systems control.
