Flow controlling tuning for the voltage of a redox flow battery considering the effect of overpotentials

Abstract

This conference paper presents a comparison between a $H_{\infty}$ control technique and a classical PID, applied on a redox flow battery system. The study presents a dynamic nonlinear electrochemical model that considers the effect of over-potentials losses in the computation of the voltage measurement. The controller is designed to regulate the output voltage of the battery. The $H_{\infty}$ controller is designed using the classical weighting function approach while the PID controller is tuned using a particle swarm optimizer. Finally, a comparison between the designed $H_{\infty}$ controller, and the classic PID is presented.
