چکیده

A model free control technique (extremum seeking) is employed to address problems of large-scale systems involving multi-agents in real-time. This thesis focuses on the use of extremum seeking control in a distributed, coordinated and a cooperative fashion to solve distributed control and optimization problems. First, the problem of maximizing the power produced in a wind farm is considered. To tackle this problem, a distributed time-varying extremum seeking control (TVESC) technique is employed to overcome the need to provide accurate models of aerodynamic wake interactions among the wind turbines. Solutions in continuous-time and discrete-time are presented. Secondly, precise knowledge of the structure of network connectivity has been utilized in solving cooperative optimization problems of multi-agent systems to achieve global objectives. In this thesis, a distributed proportional-integral extremum seeking control technique is designed to tackle such problems over unknown networks.

Multi-agent gradient climbing via extremum seeking control ?

A unified framework based on discrete-time gradient-based extremum seeking control is proposed to localise an extremum of an unknown scalar field distribution using a group of equipped with sensors. The controller utilises estimates of gradients of the field from local dithering sensor measurements collected by the mobile agents. It is assumed that distributed coordination which ensures uniform...

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...

Distributed extremum-seeking control over networks of unstable dynamic agents

In this paper, a distributed extremum seeking control technique is proposed to solve a class of real-time optimization problems over a network of dynamic agents with unknown unstable dynamics. Each dynamic agent measures a cost that is shared over a network. A dynamic average consensus approach is used to provide each agent with an estimate of the total network cost. The extremum seeking contro...

Adaptive Distributed Consensus Control for a Class of Heterogeneous and Uncertain Nonlinear Multi-Agent Systems

This paper has been devoted to the design of a distributed consensus control for a class of uncertain nonlinear multi-agent systems in the strict-feedback form. The communication between the agents has been described by a directed graph. Radial-basis function neural networks have been used for the approximation of the uncertain and heterogeneous dynamics of the followers as well as the effect o...
