Abstract

In this paper, we consider a fuel cell based distributed generation system unit which includes a PEM fuel cell, a storage element (battery), and a boost DC-DC converter. A dynamic model of the overall system is developed and a nonlinear robust control design that depends only on signal measurements available in typical practical implementations is proposed. The control design addresses both the fuel cell inputs (hydrogen and oxygen supply pressures) and PWM control of the switch in the boost DC-DC converter. Adaptations are utilized to handle uncertainty in system parameters.
