| 摘要: |
| 飞翼布局无人机利用多组气动舵面产生所需要的控制力和力矩,属于典型的过驱动系统;多组操纵舵面赋予其较高冗余配置的同时也使舵面故障率成倍增加。对横航向静不稳定的飞翼无人机而言,操纵面故障带来的力矩失衡会严重影响飞行安全,故以升降、方向舵损伤故障为例,提出一种气动为主,矢量推力为辅的控制分配方法;利用二元矢量偏转机构产生矢量推力,补偿损伤执行机构舵效,释放舵面控制裕度,恢复飞机操纵性;在气动舵面损伤的故障下,实现无人机的稳定控制。 |

| Abstract: |
| The flying-wing layout vectored thrust UAV often uses multiple sets of aerodynamic rudder surfaces and vector nozzles to jointly generate the required control force and torque, which belongs to a typical overdrive system. Multiple sets of rudder surfaces give UAV a higher redundancy configuration, but also result in multiplying the rudder surface failure rate. Especially for the statically unstable flying-wing UAV in lateral direction, the moment imbalance caused by the failure of the executive rudder will seriously affect the flight safety. Therefore, this paper takes the failure of elevator and rudder damage as an example, and proposes a kind of control distribution method of aerodynamic-based control and vectored thrust as auxiliary. The binary vector deflection mechanism is used to generate vector thrust, compensate damaged actuator mechanism rudder effect, release the control margin of the rudder actuator, and restore the maneuverability of the aircraft. Under the failure of the aerodynamic rudder actuator damage, the stable control UAV is realized. |
