Abstract: In this paper, an operator-based nonlinear control system for a polymer electrolyte fuel cell (PEFC) reformer is proposed. Firstly, structure of the reformer is introduced and modelled. Secondly, an operator-based nonlinear control system for the reformer is designed by using the model. Here, uncertainties which are assumed ΔP are considered. And the desired performance of temperature tracking is discussed. Finally, robust stability analysis and the effectiveness of the proposed control system are confirmed by simulations.
Keywords: polymer electrolyte fuel cells; PEFC reformers; robust control; right coprime factorisation; operators; uncertainties; output tracking; temperature control; nonlinear control; simulation.
