Phase-based Extremum Seeking Control
Extremum Seeking Control (ESC) is a model-free adaptive control method to locate and track the optimal working point for nonlinear plants. However, as shown recently, traditional ESC methods may not work well for dynamic systems. In this thesis, we consider a novel ESC loop to locate the optimal operating point for both static and dynamic systems. Considering that the phase-lag of the system un...
متن کاملIterative learning control based on extremum seeking
This paper proposes a non-model based approach to iterative learning control (ILC) via extremumseeking. Single-input–single-output discrete-time nonlinear systems are considered, where the objective is to recursively construct an input such that the corresponding system output tracks a prescribed reference trajectory as closely as possible on finite horizon. The problem is formulated in terms o...
متن کاملA proportional integral extremum-seeking control approach
This paper proposes an alternative extremum seeking control design technique for the solution of real-time optimization control problems. The technique considers a proportionalintegral approach that avoids the need for a time-scale separation in the formulation of the ESC. It is assumed that the equations describing the dynamics of the nonlinear system and the cost function to be minimized are ...
متن کاملExtremum Seeking Control for Energy Optimization of Vapor Compression Systems
In this paper, an energy optimizing extremum seeking controller is developed for vapor compression systems (VCS) that automatically discovers sets of inputs that minimizes the energy consumption while the machine is in operation. This controller optimizes an input-output map (from VCS inputs to electrical energy consumed) in realtime, and without relying on a model of the dynamics of a vapor co...
متن کاملInvariant Manifold Approach for Time-Varying Extremum-Seeking Control Problem
In this paper, the minimization of an unknown but measurable cost function using extremum-seeking control is considered. The main contribution of the paper is to formulate the extremum-seeking problem as a time-varying estimation problem. The concepts of invariant manifold and adaptive parameter update law are used for adaptive estimation of the timevarying gradient of the unknown cost function...
