无人机单副翼大角度卡死配平策略研究

Study on UAV's trimming strategy for single aileron jammed at a large angle

针对无人机单侧副翼大角度卡死的情况,研究了基于飞行状态的配平方法和策略选择问题。首先进行理论分析和实际计算,提出了利用侧滑角配平的方案;进而根据不同的配平方案得出配平策略:在空中飞行阶段,为了保证飞机具有较大的操纵能力,可以加入较大的侧滑角配平;在返航着陆阶段,可以加入较大的左副翼。最后通过PID控制器设计对两种配平方案分别进行了仿真验证,证明了方案的正确性及响应的快速性。

Trimming strategy based on the flight state of UAV is studied in this paper,to deal with the problem of single aileron jammed at a large angle. And then trimming with the other aileron or sideslip angle is analyzed and concluded： in the air phase,in order to ensure the aircraft has greater maneuverability,a larger sideslip angle can be used in trimming; on the landing phase,larger left aileron should be used. Finally,the simulation with PID controller design verifies the correctness and feasibility of the two methods.
