摘要:

传统四旋翼飞行器的轨迹设计和容错控制是近年来研究的热点。由于机械设计中的几何形状,每个推力的方向垂直于身体。与传统的四旋翼飞行器相比,四倾转旋翼飞行器在控制推力矢量方面具有更大的自由度。四倾转旋翼增加了推力的额外自由度,提供了违反常规四旋翼中的推力的法线方向的可能性。这提供了更大的控制灵活性的能力。本文提出了一种新型的四倾转旋翼(四锥旋翼)的设计,其推力可以沿圆锥形状的边缘分配。四锥倾转旋翼机除了继承了四锥倾转旋翼机灵活机动的优点外,还有望在严重动力故障(全部推力损失)下实现容错控制。利用SIMULINK、MATLAB对某无人机模拟器的控制效果进行了仿真。

英文摘要:

Conventional quadrotors received great attention in trajectory design and fault-tolerant control in these years. The direction of each thrust is perpendicular to the body because of the geometrics in mechanical design. Comparing with the conventional quadrotor, a novel quadrotor named quad-tilt-rotor brings better freedom in manipulating the thrust vector. Quad-tilt-rotor augments the additional degrees of freedom in the thrust, providing the possibility of violating the normal direction of the thrust in the conventional quadrotor. This provides the ability of greater agility in control. This paper presents a novel design of a quad-tilt-rotor (quad-cone-rotor) whose thrust can be assigned along the edge of a cone shape. Besides the inheriting merits in agile from quad-tilt-rotor, the quad-cone-rotor is expected to take fault-tolerant control in severe dynamic failure (total loss in all thrusts). We simulate the control result in a UAV simulator in SIMULINK, MATLAB.
