Design of a Database-driven Extremum Seeking Controller Based on a Just-in-time Approach

Abstract

In considering the efficiency and/or profitability of a system, a reference value should be set to maximize them. An extremum seeking (ES) control, a type of gradient method, does not require prior information related to the optimization function to find the extreme value of the optimization function. However, this scheme has a problem of taking time to reach an optimal value because the search point is updated repeatedly. This study proposes the database-driven extremum seeking control (DD-ES) method in order to solve the problem and applies the DD-ES to an anti-lock braking system (ABS) model to verify the effectiveness of the actual system case.
