The invention discloses a gust mitigation control system and method for a multi-control-surface aircraft, and belongs to the field of multi-control-surface aircraft control, and the method comprises a gust mitigation control law, gust mitigation control law opening and closing logic and mitigation control surface (spoiler and flap) distribution logic; the method serves as a top layer structure to be overlaid in an original control system of an aircraft, overload of gust to the aircraft can be greatly reduced by adopting a direct lift force control method under the condition that the pitching attitude of the aircraft is not changed, the gust influence can be rapidly offset, and the system has the advantages that the aircraft attitude change is small after starting, and the system reliability is high. And meanwhile, the direct lift force control method can reduce additional torque generated by control surface deflection, so that the flight path is stable.

    本发明公开了可用于多操纵面飞机的阵风减缓控制系统及方法,属于多操纵面飞机控制领域,本发明方法包括阵风减缓控制律、阵风减缓控制律启闭逻辑和减缓舵面(扰流板、襟翼)分配逻辑;此方法作为顶层结构叠加在飞机原有的控制系统中,采用直接升力控制方法可以在不改变飞机俯仰姿态情况下,大大减小阵风对飞机的过载,可以快速抵消阵风影响,本发明的系统具有开启后对飞机姿态改变小,关闭后不影响飞机正常飞行的优点,同时直接升力控制方法可以减小舵面偏转产生附加力矩,使飞行轨迹稳定。
