飞机穿越风切变的非线性动态逆控制

Nonlinear Inversion Dynamics Control during Windshear Penetration

介绍了非线性动态逆的基本原理及其在低空风切变改出飞行中的应用。利用较真实的风切变工程化模型和非线性动态逆方法,对飞机改出低空风切变的控制进行了设计。文中获得了动态逆方法控制下的改出飞行参数曲线,并与其他的改出引导策略的结果进行了对比。结果表明,动态逆方法在飞机穿越风切变的轨迹控制过程中实用有效。

The Non-linear Inverse Dynamics (NID for short) and its application in the flight control during windshear penetration are introduced here. With the employment of a real engineering windshear model and NID, a low-altitude windshear penetration flight control law is designed. The simulative calculation results indicate that the NID control logic works effectively in the trajectory control of airplane during the penetration of windshear.
