Adaptive Second-Order Sliding Mode Observer-Based Fault Reconstruction for PEM Fuel Cell Air-Feed System
TL;DR: An observer-based fault reconstruction method for PEM fuel cells using an adaptive-gain second-order sliding mode (SOSM) observer for observing the system states, where the adaptive law estimates the uncertain parameters.
Journal ArticleDOI
Control of PEMFC Air-Feed System Using Lyapunov-Based Robust and Adaptive Higher Order Sliding Mode Control
TL;DR: An experimental demonstration of the applicability of the recently developed fixed-gain robust and adaptive higher order sliding mode (HOSM) controllers for the air-feed system of polymer electrolyte membrane fuel cells, which is a nonlinear single-input, single-output system with bounded uncertainty.
Journal ArticleDOI
Effect of variation of hydrogen injection pressure and inlet air temperature on the flow-field of a typical double cavity scramjet combustor
Krishna Murari Pandey,Gautam Choubey,Fayez Shakil Ahmed,Dilbahar Hussain Laskar,Pushpdeep Ramnani +4 more
TL;DR: In this paper, a double cavity scramjet combustor has been simulated using the two-dimensional compressible Reynolds-Averaged Navier-Stokes (RANS) equations coupled with two equation standard k-ɛ turbulence model as well as the finite-rate/eddy-dissipation reaction model.
Journal ArticleDOI
Load governor based on constrained extremum seeking for PEM fuel cell oxygen starvation and compressor surge protection
Salah Laghrouche,Salah Laghrouche,Imad Matraji,Imad Matraji,Fayez Shakil Ahmed,Fayez Shakil Ahmed,Samir Jemei,Samir Jemei,Maxime Wack,Maxime Wack +9 more
TL;DR: A Load Governor based on constrained Extremum Seeking (ES) approach has been proposed in this paper, which ensures that the physical constraints of the system are not violated and the ES controller varies the LG bandwidth parameter to optimize the net power output.
Journal ArticleDOI
Comparison of robust and adaptive second order sliding mode control in PEMFC air-feed systems
TL;DR: The experimental results demonstrate the effectiveness of both controllers and highlight that the adaptive controller is more power-efficient as the adaptive gains further reduce the internal power consumption of the air-feed system.
