摘要/Abstract

摘要： 在复杂的作战和着舰环境下，舰尾气流扰动是着舰误差的最主要来源之一。如果在着舰下滑阶段利用直接升力控制（DLC）的快速性和解耦性能力，可以极大地减轻飞行员着舰操纵负担并且提高着舰最后阶段对舰尾流的抑制能力。从航迹调节和姿态稳定的解耦角度出发，提出在非线性动态逆（NDI）控制框架下实现基于直接升力的着舰控制律方法，并通过建立含有舰尾流扰动的E-2C全量飞机仿真模型进行验证。结果表明：在非线性动态逆控制中引入直接升力的舰载机着舰控制律，可以实现在着舰下滑阶段姿态稳定的同时，通过直接升力快速解耦调节航迹误差，并且在引入舰尾流干扰的情况下，具有快速修正下滑倾角误差、抑制舰尾流干扰的能力，最终达到显著提高着舰精度的效果。

Abstract: In complicated combat and landing environments, the disturbances of the air wake remains one of the main sources of ship landing errors. Utilization of the rapidity and decoupling capabilities of the Direct Lift Control (DLC) in the gliding phase can significantly reduce the pilot's controlling burden during landing and improve the suppressing ability of the air wake. From the perspective of decoupling of trajectory adjustment and attitude stability, this paper proposes to implement a precision carrier landing control law scheme based on direct lift under the framework of Nonlinear Dynamic Inverse (NDI) control, and establishes an E-2C full aircraft simulation model containing ship wake disturbances for verification. The results show that the design of the carrier-based aircraft landing control law with the introduction of DLC in the NDI can achieve a stable attitude during the landing stage, and meanwhile, rapid decoupling to adjust the track error through the direct force. In the case of introducing the ship wake interference, the simulation indicates that the control law has the ability to quickly correct the glide angle error, suppress the interference of the ship's wake, and consequently, significantly improve the landing accuracy.
