This paper is a contribution to the problem of the control of PEM Fuel Cell. More precisely, a theoretical result is proposed to prove that the oxygen excess ratio value can controlled by using a continuous state feedback. The result is established without any linearization.
In this paper, an adaptive observer for nonlinear systems is proposed in order to estimate simultaneously the system state and some possible parametric faults in the fuel cell system. The question of stability is addressed in terms of Lyapunov quadratic stability and sufficient conditions are obtained through the formulation of strict linear matrix inequalities (LMIs). The convergence of the parameter...
