Fuel Cell Voltage Regulation Using Dynamic Integral Sliding Mode Control

Fuel cells guarantee ecological ways of electricity production by promising zero emissions. Proton exchange membrane fuel (PEMFCs) are considered one the safest methods, with a low operating temperature and maximum conversion efficiency. In order to harness full potential PEMFC, it is imperative ensure membrane’s safety through appropriate control strategies. However, most strategies focus on economy along viable cell life, but they do not assure constant output voltage characteristics. A comprehensive design regulate boost voltages PEMFC under varying load conditions addressed dynamic integral sliding mode (DISMC) combining properties both SMC. The proposed system outperforms in robustness against parametric uncertainties eliminates reaching phase assured stability. hardware test rig consisting portable connected power converter using technique that regulates for loads conditions. results compared proportional (PI) based system. Both simulation provided validate technique. experimental show improvements 35.4%, 34% 50% rise time, settling time robustness, respectively.
