Dynamically Adaptive Gain Super Twisting Sliding Mode Control for Extending the range of Hydrogen Fuel Cell based Electric Vehicles

The sustainable development towards green energy enforces this proposed research paper which works on the hydrogen carrier eco-friendly Fuel Cell Based Vehicles (HFCBV). Proton exchange membrane fuel cell stack system is implemented to develop the electric fuel cell reference current which is the desired input to the next energy conversion process to drive the FC drive. An intelligent bi-directional DC-DC converter is proposed to operate the hybrid backup energy source and to enhance the power and energy density capabilities even under the hydrogen carrier energy has insufficient energy to drive the remaining circuit. An efficient and reliable estimation method is applied to obtain the optimum power and energy densities. A new dynamical adaptive sliding mode second-order sliding mode controller is applied with a new strategy to get the better adaptive control system, which mainly reduces the chattering effect which is introduced into the control system adaptive path while evaluating the performance of intelligent power converters and dynamic vehicles due to their dynamical and robust behaviour in nature. The developed fuel cell stack controlling unit along with the power and energy density management system is integrated into the permanent magnet synchronous motor along with the drive circuit which intern operates the HFCBV dynamic modelling unit.
