Abstract :
Two non-perturvative extremum seeking control approaches are analyzed; the first approach needs the sensing of the function´s gradient while the second one does not. Relationships between the algorithms parameters and their dynamic behavior are found. Also expressions for the steady state error of both approaches are derived. Finally, these results are used to verify and to compare, by means of simulation, the performance of both methods.
