Sliding mode controllers for hybrid storage system composed by battery and ultracapacitors

This paper is dedicated to the control of hybrid storage system composed by batteries and ultracapacitors. More precisely, the strategy for control is achieved by using a PWM-based sliding mode voltage and current controller. The goal is to improve the efficiency and stability of the used converters. Simulation results, obtained by using Scilab/Modelica, are given in order to highlight the relevance of the proposed approach.
