Summary:This paper studies a real-time control problem for a hybrid power system consisting of a proton exchange membrane fuel cell (FC), a unidirectional boost converter, and a lithium-ion battery. An adaptive control strategy is proposed to manage the power sharing in this hybrid power system. System constraints, including the slow dynamics of the FC and the state of charge of the battery, are explicitly considered. The controller achieves tracking a dynamically changing load demand while satisfying the system constraints based on parameter estimations. The main contribution is that, compared with the previous control methods, the proposed control design for hybrid power systems has provable stability and convergence closed-loop properties. Simulation and experimental results are provided to validate the control design.
