Energy Management Of Fuel Cell/ Supercapacitor Hybrid Source Corresponding Author. Tel: +213 (0) 6 64 5g 47 06:fax: Based On Linear And Sliding Mode Control
Résumé: This paper, presents the modelling and control strategy based on linear proportional-integral @I) and nonlinear sliding mode-based controllers of hybrid fuel celUsupercapacitor power system. This source is composed of a polymer Electrolyte Membrane Fuel Cell (PEMFC 500 w) and a supercapacitor module (800w) as a main and an auxiliaryo*"é, respectively to satisfy the load requirements in the transient and steady states. Due to the weak request on the FC, a classical pI controller has been udupt"d to control it through an interleaved boost converter. However, because of the fast response in the transient state and its ability tà work with a constant or variable frequency, a sliding mode controller has been used to manage the SCs power variation through a DC-DC bidirectional converter. The simulaüon results under Matlab/Simulink showed that the p.opor"d control strategies had managed and had controlled successfully the hybrid system \ /hich satisûed the load requirements with a stable and robust performances
