加装空中加油状态下的受油机飞行控制律设计研究

为了克服受油飞机飞行控制系统本身复杂性以及加油机干扰气流带来的影响,根据空中加油对受油飞机的要求,结合神经网络和增益调度控制,对某型飞机飞行控制系统加装空中加油状态控制律的设计进行研究。数值仿真结果表明,经过重新设计的受油机飞行控制系统,在空中加油状态下,飞机稳定性增加,并且能在规定范围内稳定地改变和保持姿态角,从而来跟踪加油机的姿态变化。

Redesign of the flight control law for receiver aircraft after adding air-refueling status

To reduce the airflow disturbance effect of tanker and considering the requirement of air-refueling to the receiver aircraft,the flight control law of a receiver aircraft after adding air-refueling system is redesigned based on neural network method and gain scheduling.The simulation results of Longitudinal-loop show that:with the redesigned flight control system,the stability of the receiver is improved at air-refueling status;every joystick longitudinal displacement corresponds to a pitch rate at stable state,and if current pitch is out of this area,the customer can restore the original operation.This relationship can be applied for Bank-loop too.
