摘要
以动力电池和超级电容组成的复合电源系统为研究对象,在合理匹配复合电源系统各参数的基础上,建立基于逻辑门限和模糊控制的复合电源系统功率分配策略.利用汽车仿真软件ADVISOR2002并对其二次开发,搭建采用复合电源系统的纯电动汽车模型,结合典型的NEDC道路循环工况分别对此两种功率分配控制策略进行仿真对比分析.结果表明,基于模糊控制策略的复合电源系统可以更好地分配动力电池和超级电容之间的功率,复合电源系统性能明显提升.
Hybrid power system （HPS） with power battery and ultra-capacitor as the research object ,the parameters of HPS was matched reasonably ,then the power distribution strategy of HPS was established based on logic threshold control and fuzzy control .A pure electric vehicle model with HPS was designed by the secondary development of vehicle simulation software AD-VISOR2002 ,and a simulation and analysis of those control strategies for power allocation was conducted with a typical NEDC driving cycle .The simulation results show that the HPS based on the fuzzy control strategy can better distribute the power between the battery and the ultra-capac-itor ,and improve the performance of HPS obviously .
