Abstract: Considering the lack of coupling in the energy system modeling of solar powered Unmanned Aerial Vehicles (UAVs) and the incomplete description of energy flow process, this paper introduces multiple factors affecting the operation of the energy system in different dimensions such as the external atmospheric environment and UAV attitude angle, into the modeling process. The modeling process of the heterogeneous atmospheric environment model, the aircraft motion model, the motor model, the decelerator model, the propeller model, the photo-voltaic cell model and the battery model are presented successively. Meanwhile, the coupling relationships among the models are established to obtain the coupling model reflecting the dynamic flight behavior in inhomogeneous atmospheric environments. Simulation results show that the coupling model can comprehensively describe the coupled effects, such as the influence of the external atmospheric environment and the UAV attitude angle on the generated power and dynamic load power, and that the coupling model proposed is suitable for simulation analysis and construction of the ground hardware-in-the-loop simulation platform.
