本文提出了基于PI和非线性滑模控制器的混合燃料电池/超级电容器电源的建模和控制策略。它由一个聚合物电解质膜燃料电池（PEMFC 500 W）和一个超级电容器堆（800 W）组成，分别作为主电源和辅助电源，以满足瞬态和稳态的负载要求。一个经典的PI控制器已被适配来控制直流母线电压，并确定FC的参考电流。由于在瞬态中的快速响应及其以恒定或可变频率工作的能力，滑模控制器已被用于分别控制通过升压和DC-DC双向转换器的SC和FC电流。在Matlab/Simulink下的仿真结果表明，所提出的控制策略成功地管理和控制了混合系统，满足了负载要求，具有稳定性和鲁棒性。
This paper presents the modelling and control strategies based on PI and nonlinear sliding mode controllers of a hybrid fuel cell/supercapacitor source. It is composed of a Polymer Electrolyte Membrane Fuel Cell (PEMFC 500 W) and a supercapacitor stack (800 W) as a main and an auxiliary sources respectively, to supply the load requirements in the transient and steady states. A classical PI controller has been adapted to control DC bus voltage and to determine the FC's reference current. Due to the fast response in the transient state and its ability to work with a constant or variable frequency, a sliding mode controllers have been used to control the SC and FC currents through boost and DC-DC bidirectional converters, respectively. The simulation results underMatlab/Simulink showed that the proposed control strategies managed and controlled successfully the hybrid system and satisfied the load requirements with a stable and robust performances.
