Title: Sub-optimal extremum seeking
Being able to keep margins with respect to the optimum of a performance index is a requirement that may arise in several applications. Such a reserve can be used as a knob for counteracting any changes in the operating conditions of the system. In most of the situations, the system dynamics as well as the analytical expression of the cost function are only partially known from the designer. Extremum seeking control is able to steer such systems for optimizing the cost function output. Starting from classical results, we present in this talk a modified version of the extremum seeking control that is able to not reach the cost function maximum but to keep a desired margin with respect to its estimated maximum.
Christophe Labar received his master degree in electro-mechanical engineering from the Université Libre de Bruxelles (ULB), Belgium, in 2015. He started then a PhD in the department of Control Engineering and System Analysis, at ULB. In 2016, he received the Solvay Awards (Solvay Institute) for his master thesis. His research interests include extremum seeking control, singular perturbation and averaging, wind farms and bio-medical robotics.
