摘　　要：针对燃料电池动态响应上的不足,本文探讨了燃料电池发电系统中的能量管理控制系统的设计方法。讨论了能量管理控制系统的结构和控制器的设计,提出了一种基于电流间接控制的能量管理控制方式。建立了能量管理控制系统的控制模型,重点分析了控制系统中电流控制环路的设计方法,设计了能量管理环节中的电流控制器。建立了5kW燃料电池发电系统,通过实验验证了所设计的能量管理控制系统的有效性。Fuel ceil is known as a slow dynamic response application, in this paper, the energy management design for Fuel Cell power system is discussed to solve the limitation. The structure and the controller design of the energy management system are discussed. An energy management control system based on indirectly current control is proposed in this paper. The system model is obtained based on a practical fuel celt power system. The design process of the energy management control system is presented and the current control loop design is discussed in detail. The current controller of the energy management is designed based on the analysis. Finally, the experiment results on a 5 kW fuel cell power system with energy management are given to verify the Cneoretical analysis.
