摘要

针对太阳能无人机能源系统建模的耦合性考虑不足、能量流动过程描述不全面等问题，将外部大气环境、无人机的姿态角度等不同维度下影响能源系统运行的多个因素纳入到建模过程中，先后给出了非均质大气环境模型、无人机运动模型、电机模型、减速器模型、螺旋桨模型、光伏电池模型和蓄电池模型的建立过程，并建立了各模型间的耦合关系，得到反映非均质大气环境下、动态飞行行为的太阳能无人机中能量流动的耦合模型。仿真结果表明：该模型可以完整的描述外部大气环境和无人机飞行姿态对无人机发电功率以及动力负荷功率的影响等耦合作用，适合用于仿真分析和地面半实物仿真平台的搭建。

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.
