Title (EN) METHOD AND SYSTEM FOR USING LOGARITHM OF POWER FEEDBACK FOR EXTREMUM SEEKING CONTROL
(FR) PROCÉDÉ ET SYSTÈME D'UTILISATION D'UN LOGARITHME DE RÉACTION DE PUISSANCE EN VUE D'UN CONTRÔLE DE RECHERCHE D'EXTREMUM
Abstract:
(EN) The present disclosure provides a method and system for optimizing a control process. The method and system comprise using a sensor to generate a feedback signal that represents a measured performance index for an extremum seeking control (ESC) method and sending the feedback signal to an ESC conditioning circuit that applies a logarithmic transformation to the feedback signal to obtain a modified feedback signal. An ESC controller applies the modified feedback signal to the ESC method to generate an output value that is used to control an actuator to maximize the performance of a machine or process.
(FR) La présente invention concerne un procédé et un système d'optimisation d'un processus de contrôle. Le procédé et le système consistent à utiliser un capteur pour générer un signal de réaction qui représente un indice de performance mesuré concernant un procédé de contrôle de recherche d'extremum (ESC), et à envoyer le signal de réaction à un circuit de conditionnement d'ESC qui applique une transformation logarithmique au signal de réaction de façon à obtenir un signal de réaction modifié. Un contrôleur ESC applique le signal de réaction modifié au procédé ESC de façon à générer une valeur de sortie qui est utilisée pour commander un actionneur afin d'optimiser les performances d'une machine ou d'un processus.
