Abstract :
In this paper we consider extremum seeking for plants that can be represented as a series connection of an integrator chain and an unknown nonlinear system. Using recent results on singularly perturbed Lie bracket approximations we develop an extremum seeking scheme that exploits the special structure of the plant. We illustrate our results by means of a source-seeking example for double integrator vehicles.
