Lie bracket approximation of extremum seeking systems
Extremum seeking feedback is a powerful method to steer a dynamical system to an extremum of a partially or completely unknown map. It often requires advanced system-theoretic tools to understand the qualitative behavior of extremum seeking systems. In this paper, a novel interpretation of extremum seeking is introduced.We show that the trajectories of an extremum seeking system can be approxim...
متن کاملNash Equilibrium Seeking in Multi-Vehicle Systems: A Lie Bracket Approximation-Based Approach
We consider problems in multi-agent systems where a network of autonomous vehicles needs to self-organize such that some global objective function is maximized. To deal with the agents’ lack of global information we define the problem as a potential game where the agents/players are only able to access local measurements of their individual utility functions whose parameters and detailed analyt...
متن کاملNon-C Lie Bracket Averaging for Nonsmooth Extremum Seekers
A drawback of extremum seeking-based control is the introduction of a high frequency oscillation into a system’s dynamics, which prevents even stable systems from settling at their equilibrium points. In this paper, we develop extremum seeking-based controllers whose control efforts, unlike that of traditional extremum seeking-based schemes, vanish as the system approaches equilibrium. Because ...
متن کاملModel-based Extremum Seeking
One possible way to approach these kind of problems is extremum seeking. A key feature of common extremum seeking schemes is that they are model free, i.e. the plant is treated as a black box and no model is required. However, this leads to low performance and reduces its range of applicability. In this work we want to overcome these drawbacks by designing extremum seeking schemes that incorpor...
متن کاملFast extremum seeking on Hammerstein plants: A model-based approach
Partial plant knowledge may be used to develop model-based extremum seekers; however, existing results rely on a type of time-scale separationwhich leads to slow optimization relative to the plant dynamics. In this work, a fast model-based extremum seeking scheme is proposed for a Hammerstein plant, and semi-global stability results are provided. The structure of a Hammerstein plant is used to ...
