Control of Fuel Cell Power Systems: Principles, Modeling, Analysis and Feedback Design
TL;DR: In this article, the authors present an analysis and simulation of the FCS air flow control for fuel cell cathode Oxygen Reactant (OCO) and Natural Gas Fuel Processor (NGFP).
Journal ArticleDOI
Control of fuel cell breathing
TL;DR: In this paper, the authors analyzed and designed air flow controllers that protect the fuel cell (FC) stack from oxygen starvation during step changes of current demand, and used linear optimal control design to identify the frequencies at which there is a severe tradeoff between the transient system net power performance and the stack starvation control.
Journal ArticleDOI
Recursive least squares with forgetting for online estimation of vehicle mass and road grade: theory and experiments
TL;DR: In this article, an ad hoc modification of the update law for the gain in the recursive least square (RLS) scheme is proposed and used in simulation and experiments, demonstrating that the proposed scheme estimates mass within 5% of its actual value and tracks grade with good accuracy.

A lumped-parameter electro-thermal model for cylindrical batteries
Xinfan Lin,Hector E. Perez,Shankar Mohan,Jason B. Siegel,Anna G. Stefanopoulou,Yi Ding,Matthew P. Castanier +6 more
TL;DR: In this paper, an electro-thermal model for cylindrical batteries is presented, which consists of two sub-models, an equivalent-circuit electrical model and a two-state thermal model which are coupled through heat generation and temperature dependence of the electrical parameters.
