Abstract:
The fast depletion of fossil fuels, oil, and natural gas due to their excessive use is a source
of motivation for finding alternative ways for overcoming their rapid depletion. Global
warming is also an important issue caused by the emission of harmful gases. Therefore,
various studies have been carried out on FC-based hybrid electric vehicles (FCEVs) to
tackle the issue of natural resources depletion and emission of harmful gases. In this
paper, the proposed model consists of four sources namely Fuel Cell (FC), solar panel,
battery, and a supercapacitor (SC). The FC is the primary source whereas the other
three sources act as secondary sources. All the sources are connected via DC converters
to a DC bus. A supertwisting sliding mode non-linear controller has been formulated
for the hybrid energy storage system. The system’s global stability has been assured
through Lyapunov criteria. The proposed model is simulated in MATLAB/Simulink
2021b for verifying controller performance. The results of the controller are verified
through dSPACE RTI1202 hardware. Both the simulation and the hardware results
authenticate stability, robustness, and efficient performance under various dynamic con ditions.
