摘要
无人机在着陆过程中地面滑跑阶段的运动特性与空中飞行时不同,建立无人机在这一阶段的数学模型,对进一步深入研究实现无人机安全着陆具有重要意义。本文以某型无人机为背景,对无人机进行详细的受力分析,研究并建立了地面滑行阶段的非线性数学模型。并在Matlab/Simulink平台上对其进行仿真,通过仿真结果与实际飞行状态数据的对比,表明模型可用。
In the course of landing, the UAV has the unique dynamical characteristics in ground motion different from that of flight, Establishing the mathematics model of unmanned plane in this stage has important meaning for realizing the safe landing of UAV. As regards a certain type of UAV, the strength pressed on the UAV is analyzed; a nonlinear modal of UAV in ground motion is established, With the simulation environment of Matlab/Simulink, a simulation system is designed. The comparison between data of real state of flight and simulation result indicates that the model can be used,
