大型运输机推力不对称补偿控制律设计

为了补偿推力不对称对大型飞机造成的影响,基于推力不对称对飞机姿态及运动的影响分析,提出了引入侧滑角反馈的横航向控制律补偿方案,并进行了仿真验证。仿真结果表明,补偿后的控制律能够减小侧向偏离、侧滑角及滚转角,保持航向和飞行姿态,从而减轻了飞行员负担,保证了飞行安全。

Design of asymmetric thrust compensation control law for the large transport aircraft

In order to compensate the influence of the asymmetric thrust on the large transport aircraft,based on the analysis of airplane attitude and dynamic characteristics at the asymmetric thrust condition,a compensation method with the side slip angle feedback was proposed and simulated as well.Simulation results show that the control law effectively decreases lateral deviation,side slip and roll angel,holds direction heading and flight attitude,which could relieve the flight burden and ensure the flight safety.
