飞机穿越风切变时的地速/空速控制

Ground-Speed/Air-Speed Control of Airplane During Penetration of Windshear

为解决飞机穿越风切变过程中控制系统解耦和飞行轨迹的实时 /在线控制问题 ,对飞机纵向三自由度非线性模型 ,运用非线性动态逆方法 ,在风轴系中设计了飞行轨迹的高度变化率 /空速控制模式 ,在地轴系中设计了高度变化率 /地速控制模式 .对 2种控制模式进行比较并将其结合起来 ,得到更加完善的地速 /空速控制律 .

To design the control logic during the penetration of wind shear, nonlinear inverse dynamics method was employed to achieve the decoupling of the nonlinear flight control system and the implementation of the real-time/on-line control for the flight trajectory. Climb rate/air speed control mode in the wind-coordinate system and climb rate/ground-speed control mode in the ground-coordinate system were developed. These two modes were integrated to form ground speed/air speed control law. The simulative calculation results show that the nonlinear inverse dynamics method works effective in the trajectory control of airplane during the penetration of wind shear.
