垂直起降固定翼无人机混合动力系统参数匹配
VTOL fixed-wing UAV hybrid system parameter matching
摘要
Abstract
Fuel cell UAVs have become a research hotspot in green aviation because of their high efficiency,pollu-tion-free emissions and high energy density.Parameter matching of fuel cell hybrid system has an important impact on the economy,environmental protection and efficiency of UAVs.In this study,a vertical take-off and landing(VTOL)fixed-wing UAV is used as a hybrid system of fuel cell+lithium-ion battery.According to the technical indicators,the components of the UAV power system are selected.Firstly,the topology of fuel cell hybrid system is designed,and the parameters of fuel cell,lithium battery,brushless DC motor,propeller and unidirectional DC/DC converter in the hybrid system are matched.Then,the load power is created according to the task profile,and finally the MATLAB/Simulink simulation analysis of the hybrid system is carried out using the finite state ma-chine energy management control strategy.The results show that the designed fuel cell hybrid system can meet the flight load requirements,meet the changes of working conditions during flight,and achieve zero-emission flight.关键词
