Purpose

The purpose of this paper is to design an innovative autonomous carrier landing system (ACLS) using novel robust adaptive preview control (RAPC) method, which can assure safe and successful autonomous carrier landing under the influence of airwake disturbance and irregular deck motion. To design a deck motion predictor based on an unscented Kalman filter (UKF), which predicts the touchdown point, very precisely.

Design/methodology/approach

An ACLS is comprising a UKF based deck motion predictor, a previewable glide path module and a control system. The previewable information is augmented with the system and then latitude and longitudinal controllers are designed based on the preview control scheme, in which the robust adaptive feedback and feedforward gain’s laws are obtained through Lyapunov stability theorem and linear matrix inequality approach, guarantying the closed-loop system’s asymptotic stability.

Findings

The autonomous carrier landing problem is solved by proposing robust ACLS, which is validated through numerical simulation in presence of sea disturbance and time-varying external disturbances.

Practical implications

The ACLS is designed considering the practical aspects of the application, presenting superior performance with extended robustness.

Originality/value

The novel RAPC, relative motion-based guidance system and deck motion compensation mechanism are developed and presented, never been implemented for autonomous carrier landing operations.

F/A-18机载机自主着陆鲁棒自适应预控设计

目的

本文的目的是使用新颖的鲁棒自适应预览控制 (RAPC) 方法设计一种创新的自主航母着陆系统 (ACLS)，该系统能够在气流扰动和不规则甲板运动的影响下确保安全和成功的自主航母着陆。设计基于无迹卡尔曼滤波器 (UKF) 的甲板运动预测器，非常精确地预测着陆点。

设计/方法/方法

ACLS 包括基于 UKF 的甲板运动预测器、可预览下滑路径模块和控制系统。系统增加了可预览信息，然后基于预览控制方案设计了纬度和纵向控制器，其中通过李雅普诺夫稳定性定理和线性矩阵不等式方法获得鲁棒自适应反馈和前馈增益定律，保证闭环系统的渐近稳定性。

发现

通过提出稳健的 ACLS 解决了自主航母着陆问题，该方法在存在海扰和时变外部扰动的情况下通过数值模拟进行了验证。

实际影响

ACLS 的设计考虑了应用的实际方面，具有卓越的性能和扩展的稳健性。

原创性/价值

开发并展示了新颖的 RAPC、基于相对运动的制导系统和甲板运动补偿机制，但从未用于自主航母着陆操作。
