摘要

摘要:
以串联式结构作为航用油电混合系统能量管理方法研究的对象，针对发动机不同的负载匹配形式对能量管理进行研究。基于MATLAB/SIMULINK软件搭建一套研究能量管理方法的仿真平台，其中动力部件性能由实验获得，分别搭建了以PSO算法为基础的全局优化策略以及基于ECMS的瞬时优化策略，并应用于仿真平台。计算结果表明：考虑发动机变负载的匹配形式后，不同的能量管理方法下的耗油量相比于不变负载均有所降低，在全局优化策略下降低了6.27%；在瞬时优化策略下降低了7.4%。

Abstract:
Taking the series structure as the research object of the energy management method of the aviation fuel-electric hybrid system, the energy management was studied according to different load matching forms of the engine. A simulation platform for studying energy management methods was built based on MATLAB/SIMULINK software, whereby the performance of power components was obtained by experiments. The global optimization strategy based on PSO algorithm and the instantaneous optimization strategy based on ECMS were built and applied to the simulation platform. The calculation results showed that after considering the matching form of engine variable load, the fuel consumption under different energy management methods was reduced compared with the constant load, and the global optimization strategy was reduced by 6.27%; the instantaneous optimization strategy decreased by 7.4%.
