Commande d’un moteur à courant continue alimenté par un panneau photovoltaïque via un convertisseur DC-DC

Abstract

The use of power converters is becoming more and more important. We are interested in this work in the modeling of DC-DC converters and the development of control laws. For this reason, various control strategies are tested in this work to regulate DC motor output voltage with DC-DC converters. And we have seen that PI control applied to DC electric motors is a regulator that can provide good performance. We have made a study and simulation of the LRCM method for PV systems and its application to control a DC motor via a Buck converter and under variable radiation and temperature conditions.
