Abstract:
|
This paper presents the design of a sliding mode
control strategy through an input decoupling of an hybrid
fuel cell based system. The hybrid system is composed by a
fuel cell stack and a Supercapacitors module, connected to a
single DC bus. A continuous conduction mode MIMO model is
considered and the control strategy for the system is discussed.
The latter is developed using a diffeomorphism to decouple
the control inputs to surface interactions. Finally, an adaptive
switching function for the two inputs is designed to robustly
reject system perturbations and parameters variations. The
control strategy is then evaluated through extensive simulation,
considering strong load demand variations. |
