Abstract

A flatness based control of a hybrid system composed of a fuel- cell and an ultracapacitor is investigated and implemented in this paper. For this purpose, at first, the system is provided to be flat and an expression which takes into account the power losses in converters is extracted to control variables. Three control methods, sliding mode, state feedback and classical PI controllers are considered to ensure the control of the flat outputs to their references. The dSPACE-based implementation results are presented to validate operation of each control method in the purposed hybrid system.
