摘要: 针对四旋翼飞行器欠驱动性,提出一种用于自主降落的倾转四旋翼模型。该模型通过使用四个舵机对电机方向的控制来对位置(y)和姿态(roll)进行解耦,可实现倾斜悬停与倾斜飞行,增大了无人机的灵活性,提高了对无人机的位置和姿态的精确控制,使得跟踪和降落效果得到了提高。选取5次多项式来规划轨迹,以求鲁棒性强、距离最优。运用Matlab/Simulink对倾转四旋翼模型分析并验证,结果表明具有该结构的飞行器能够更加快速、准确地降落在斜面或移动平台上。

Abstract: Aiming at the under-actuation of general quadrotors, a novel quad tilt rotor model is proposed. The model decouples the y-direction translation and roll rotation of a quadrotor by the four servos used respectively for the tilting control of the four propellers to realized the tilt hover and tilt flight of the UAV, the UAV can keep a tilt attitude which increases the maneuverability and the precise pose position and attitude control of the tilt UAV and ensures a good performance on the trajectory tracking and landing. A 5-degree polynomial optimization is used in UAV trajectory planning for the strong robustness and optimal distance. The quad tilt rotor model is verified by Matlab/Simulink, and the results show that the aircraft with the proposed model could land on a slope or moving platform more quickly and accurately.

Key words: quadrotor, tilt rotor, landing, decoupling control, trajectory planning
