摘要 为保障在迎角传感器失效,且飞机处于大机动状态的情况下的飞行安全,提出了一种利用俯仰角速度重构迎角信号的方法并进行仿真验证。首先,分析了俯仰角速度重构迎角的原理;然后,在控制系统中建立重构控制律结构;最后,利用插值方法计算重构环节参数;仿真结果表明,设计的迎角重构方法能够限制迎角,为飞行员提供调整时间,保障飞行安全。 In order to ensure flight safety during the disability of Angle Of Attack (AOA) sensors and the maneuver of aircraft, a reconfiguration method of AOA by pitch rate was proposed and proved by simulation. Firstly, the principle of reconfiguration was analyzed. Secondly, the reconfiguration control law structure was established in control system. Finally, the reconfiguration parameters were calculated by interpolation. The simulation results show that the method of reconfiguration can limit AOA and provide adjustment time for pilot to ensure flight safety.
