Fuzzy PID control of a stand-alone system based on PEM fuel cell (2015)
Journal Article
Rakhtala, S. M., & Shafiee Roudbari, E. (2016). Fuzzy PID control of a stand-alone system based on PEM fuel cell. International Journal of Electrical Power and Energy Systems, 78, 576-590. https://doi.org/10.1016/j.ijepes.2015.12.003

Fuel cell (FC) systems are appropriate candidates as alternative energy sources for use in stand-alone applications. However, the FC generates an unregulated voltage, which is not suitable in stand-alone application usage solely. This paper presents...

Control of PEM fuel cell system via higher order sliding mode control (2012)
Journal Article
Rostami, S. M. R., Noei, A. R., & Gaderi, R. (2012). Control of PEM fuel cell system via higher order sliding mode control. International Journal of Automation and Control, 6(3-4), 310-329. https://doi.org/10.1504/IJAAC.2012.051892

This paper presents a multi-input multi-output (MIMO) dynamic model of polymer electrolyte membrane (PEM) fuel cells. A non-linear controller is designed to prolong the stack life of the PEM fuel cell. A moderate deviation between hydrogen and oxygen...

Proton exchange membrane fuel cell voltage-tracking using artificial neural networks (2011)
Journal Article
Rakhtala, S. M., Ghaderi, R., & Ranjbar Noei, A. (2011). Proton exchange membrane fuel cell voltage-tracking using artificial neural networks. Journal of Zhejiang University Science C, 12(4), 338-344. https://doi.org/10.1631/jzus.C0910683

Transients in load and consequently in stack current have a significant impact on the performance and durability of fuel cells. The delays in auxiliary equipments in fuel cell systems (such as pumps and heaters) and back pressures degrade system perf...
