Interconnection and damping assignment passivity-based control of a fuel cell system

This paper presents the design of a non-linear controller for an energy hybridization structure involving a hydrogen fuel cell with supercapacitors for applications with high instantaneous dynamic power. The design of the controller is based on the interconnection and damping assignment - passivity based control, and compared with a standard controller strategy based on proportional-integral controller. The stability properties, the number of degree of freedom and performances of both controllers are discussed.
