Traditional sliding mode controller applied to a DC/DC boost converter for the improvement and optimization of the proton exchange membrane fuel cell (PEMFC) system efficiency, has the drawback of chattering phenomenon. Thus, based on the analysis of the mathematical model of PEMFC, this paper addresses the second order super twisting algorithm (STA) as a solution of chattering reduction, Stability...
The Proton Exchange Membrane Fuel Cell (PEMFC) is one of the most important power supplies. Maintaining a constant voltage in PEM fuel cells with the presence of inputs and load variations, has always attracted the attention of many researchers and many articles have been published on this issue. This paper presents modeling of a PEM fuel cell connected to DC/DC boost converter. Subsequently, proportional...
A model of a stand-alone Proton Exchange Membrane Fuel Cell PEMFC power supply for AC motor application is studied in this paper. As an AC load, a permanent magnet synchronous motor PMSM is chosen. The power conversion chain is basically composed of DC-DC boost converter and DC-AC inverter to increase and regulate the generated voltage by the PEMFC in order to satisfy the load requirements. Then,...
This paper presents a robust Sliding Mode Controller (SMC) for Proton Exchange Membrane Fuel Cell (PEMFC). The aim of this work is to keep the PEMFC working at its maximum operating power point in presence of inputs and load variations. However, due to the low output voltage of the PEMFC, DC/DC boost converter is used to obtain regulated high voltage DC. Therefore, the SMC is proposed to fix the fuel...
Proton Exchange Membrane fuel cell (PEMFC) is hybridized to share the current in a Hybrid Electrical Vehicle (HEV) power demand. The performance of the PEMFC model is analyzed for various loads connected nearer to the permanent magnet synchronous machine (PMSM), this latter is used to drive the air-compressor of a 6 kW fuel cell (EC) which will be beneficial for Electric Vehicle (EV) application....
Considering limited ability of Proton Exchange Membrane Fuel Cell (PEMFC) systems to produce power, it is necessary to provide conditions, in which, the maximum power of the PEMFC can be achieved. The maximum power point tracker has an important role in increasing the efficiency of the PEMFC. One of its difficulties is rapid changes in operating conditions which affects on the maximum power point...
This paper presents a comparision between two controllers for Proton Exchange Membrane Fuel Cell PEMFC power system. The aim of this work is to keep the PEMFC working at its MPP by acting on the DC/DC converter, and ensure an adequate robustness against load and inputs variations. Conventional controller PI and backstepping technique are applied to the DC/DC boost converter. The stability of the backstepping...
