Abstract

This paper presents adaptive sliding mode control design for power electronic interface of fuel cell system to follow the desired reference values. The output voltage of fuel cell stack, the output load of boost converter and in grid-connected case, the line impedance are assumed as unknown parameters and they are adaptively estimated. High efficiency of proposed controllers is investigated through simulation results. A comparison study is carried out with conventional PI controller for grid-connected FC DGs.
