摘要
以燃料电池大客车为研究对象,根据其经济性、可靠性以及低成本的需求,提出了一种包含两套独立的燃料电池、直流/直流变换器及电机的双驱动动力系统结构形式.该结构在通过动力系统的冗余设计提高整车可靠性的同时,为进一步提高整车经济性的控制方法提供了更为广阔的空间.在此基础上,采用了遗传算法的优化方法,提出了一种双电机转矩优化分配控制策略,并通过路况实验验证了控制策略的有效性.
A double power structure, which includes two sets of power train system （FCE ＋ DC/DC ＋ motor）, is presented for the hybrid power system of a fuel cell bus to meet the requirement in economy, stability and low cost. The bus reliability is improved by redundancy power system, which also prorides much more space for improving the economical performance. A distribution strategy of double electric motors torque is studied with GA algorithm methods. Finally, simulation and calculation are carried out and the results show that the algorithm is feasible.
