The invention relates to the field of unmanned aerial vehicle manufacturing and the like in the high-end equipment manufacturing industry, in particular to a fixed-wing aircraft landing control method, a storage medium and an unmanned aerial vehicle. The fixed-wing aircraft landing control method comprises the steps that according to the maximum deflection range of a flap, the flap balance angle is determined, and the fixed-wing aircraft enters a leveling section at the flap balance angle; in a flap control channel, a real-time given lifting speed is determined according to an initial given lifting speed when the fixed-wing aircraft enters a leveling section and an expected lifting speed when an undercarriage is grounded; determining a flap deflection instruction according to the real-time given lifting speed; in an elevator control channel, a real-time given pitch angle is determined according to the pitch angle of the fixed-wing aircraft entering the leveling section and the optimal grounding pitch angle; an elevator skewness command is determined from a real-time given pitch angle. Pitch angle control and lifting speed control are decoupled, and the problem of coupling of the lifting speed and a pitch angle control loop can be solved.

    本发明涉及高端装备制造产业中无人航空器制造等领域,尤其涉及一种固定翼飞行器着陆控制方法、存储介质及无人机。本发明固定翼飞行器着陆控制方法包括:根据襟翼的最大偏转范围,确定襟翼平衡角,令固定翼飞行器以该襟翼平衡角进入拉平段;在襟翼控制通道中,根据固定翼飞行器进入拉平段时的初始给定升降速度和起落架接地时的期望升降速度确定实时给定升降速度;根据实时给定升降速度确定襟翼偏转指令;在升降舵控制通道中,根据固定翼飞行器进入拉平段的俯仰角和最佳接地俯仰角确定实时给定俯仰角;根据实时给定俯仰角确定升降舵偏度指令。本发明将俯仰角控制与升降速度控制解耦,可以解决升降速度与俯仰角控制回路的耦合问题。
