摘要
在无人机空中飞行的过程中,风场对无人机飞行姿态和航迹的影响是必然的,分析不同风况下所引起的飞行姿态和航迹的变化不仅有利于对无人机飞行力学的理解,更有利于对飞行控制参数调节方法的掌握。首先建立了常值风场模型,然后以某型号无人机为例,推导出其在常值风场影响下的空中飞行全量非线性动力学模型,最后基于Matlab/Simulink无人机六自由度飞行仿真系统,对不同风况下的无人机无控飞行进行仿真,分析了不同风况下的姿态与航迹的变化原因。
In the progress of UAV flying, the influence from the wind to the flight attitude and track is in- evitable, and the analysis of different wind environment influence on the flight attitude and track is bene- fit for the comprehension of flight mechanics and the regulation of control parameters. This paper firstly established the constant wind dynamic mode, then deduced the flight full variable nonlinear dynamic model with the influence of constant wind. Finally it simulated the UAV uncontrolled flight and analyzed the causes of changing attitude and track in different wind conditions based on the Matlab/Simulink 6- DOF flying simulation system.
