小型飞翼布局无人机控制律设计与试飞验证

摘要

For a due to the cancellation of the vertical tail and horizontal tail result in decreased stability, especially unstable heading for flying-wing. We design the flight control law for the full process base on the scaled flying-wing aircraft. Taking certain type shrinkage ratio aircraft of flying-wing as the control object, analysis aerodynamic characteristics of the aircraft longitudinal and lateral directional, and using eigenstructure assignment method, respectively, the longitudinal and lateral directional add stability design. The simulation results and actual test data show that, the control law can track a desired trajectory effectively, inhibit the gust disturbance, and has great practical significance.%针对无尾飞翼布局的无人机由于取消了水平尾翼和垂直尾翼，导致纵向、横航向的稳定下降，特别是横航向变为静不安定的问题，设计一种小型飞翼布局无人机全流程飞行控制律。以某型飞翼布局飞机的缩比飞机为控制对象，分析该飞机纵向与横航向的气动特性，采用特征结构配置方式，分别对纵向与横航向进行增稳设计。仿真与实际试飞结果表明：该控制律能够很好地跟踪期望的轨迹，并能有效地抑制侧风扰动，具有良好的工程应用价值。
