Abstract：The compound-wing vertical take-off and landing(VTOL)unmanned aerial vehicle(UAV)with a maximum takeoff mass of 25 kg is selected as the research object for a hybrid propulsion system.A mathematical model of key components in the power system is constructed using the MATLAB/Simulink platform.Furthermore,an integrated system-level simulation model of the compound-wing UAV hybrid propulsion system is developed.Based on the flight mission requirements of the compound-wing UAV in a multi-point hover operation scenario,corresponding flight mission profiles are designed.An energy management strategy based on equivalent minimum fuel consumption is employed.Simulation experiments are conducted to validate the proposed models and strategies.The simulation results demonstrate that the throttle response of the UAV power system based on the equivalent minimum fuel consumption energy management strategy(ECMS)meets the practical operational requirements of the UAV.The state of charge of the power battery can be maintained near the set value,with a relative error of less than 1.5%.In comparison with rule-based energy management strategies,the hybrid propulsion system UAV based on the ECMS exhibits a reduction in fuel consumption of 6.07%and 5.49%in point-to-point flight and multi-point hover operation scenarios,respectively.
