摘要
以高效率和低排放的燃料电池汽车为研究对象,使用模糊控制对燃料电池混合动力汽车的能量分配进行实时管理,在满足功率跟随的条件下保证动力电池的充放电能力,以提高燃油经济性。本次研究中,以燃料电池发动机和动力电池组作为动力源,使用Matlab软件进行动力系统建模和模糊逻辑策略应用,最后进行了仿真计算。仿真结果显示经过优化的模糊控制能量管理可以为燃料电池汽车提供好的燃油经济性和系统效率。
Fuel cell hybrid electric vehicle has been focused for alternative powertrain due to their high efficiency and low emission. This paper presents a real time fuzzy logic controller （FLC） approach to design a power management strategy for a hybrid electric vehicle. The purpose is to meet power requirement and keep the battery with good charge and discharge capacity to achieve good fuel economy. The fuel cell （FC） and battery （B） are the primary and secondary power sources. Matlab is used to model the electrical and power system of the hybrid vehicle and implement a fuzzy logic strategy. Simulation results show that optimally designed and controlled fuzzy logic can provide good fuel e- conomy and overall system efficiency for the fuel cell hybrid vehicle.
