摘要

无人机的运动受到其与邻近各种表面的相互作用的极大影响。在本文中，我们通过对其动态响应的数学建模，解决了无人机面临的被称为“地面效应”的空气动力学挑战。AR无人机2.0已被用于收集参数的变化，如在光滑表面上不同高度的滚转和俯仰。在MATLAB R2013a上对所获得的数据进行了分析，并建立了数学模型，对其进行校正，以实现更稳定的起飞、着陆和近地飞行。无人机的控制器通过不断调整来稳定无人机。结果表明，所建立的模型可用于对抗无人机的地面效应。获得的模型也将减少对控制器的压力，并且它将消耗更少的功率，因为它不必在试图稳定无人机时花费额外的功率。

Analysis of ground effect on multi-rotors

The motion of a UAV is greatly influenced by its interaction with different kinds of surfaces in proximity. In this paper, we address the aerodynamic challenge termed as `The ground effect' faced by a UAV, by mathematical modelling of its dynamic response. An AR Drone 2.0 has been used to collect the variations of parameters such as roll and pitch at different heights above a smooth surface. The data thus obtained has been analyzed on MATLAB R2013a and mathematical models have been created to correct them for a more stable take-off, landing and near ground flights. The controller in a UAV constantly adjusts to stabilize the UAV. Results show that model obtained can be used to counter the ground effect in UAVs. The model obtained would also decrease stress on the controller and it will consume less power as it would not have to expend extra power in attempting to stabilize the UAV.
