ABSTRACT The automatic carrier landing system (ACLS) is an indispensable component of modern aircraft carriers, and it can be considered a special cyber-physical system. However, the disturbance of the carrier air-wake in the final approach is detrimental to the landing safety and complicates the design of the ACLS. An air-wake rejection control strategy can be designed by analyzing the signal flow chart. To suppress the air-wake disturbance, the ACLS in this study is designed based on an adaptive backstepping sliding mode control. This design compensates and restrains the flight performance deviation, and it can also ensure the robustness of the system. Compared with the conventional ACLS design, the capability to restrain the flight performance deviation is significantly enhanced. The simulation results show that the system robustness is improved significantly. Moreover, the proposed design can achieve strict control of the ideal glide slope tracking and realize safe landing under the air conditions of the final approach.

航母纵向自动着陆信息物理系统的空气尾流抑制控制设计

摘要 航母自动着陆系统（ACLS）是现代航母不可或缺的组成部分，可以认为是一种特殊的信息物理系统。然而，在最后进近时对载气尾流的干扰不利于着陆安全，并使ACLS的设计复杂化。通过对信号流图的分析，可以设计出空气尾流抑制控制策略。为了抑制空气尾流扰动，本研究中的 ACLS 是基于自适应反步滑模控制设计的。这种设计补偿和抑制了飞行性能偏差，同时也保证了系统的鲁棒性。与传统的ACLS设计相比，抑制飞行性能偏差的能力显着增强。仿真结果表明，系统鲁棒性得到显着提高。此外，所提出的设计可以实现对理想下滑道跟踪的严格控制，并在最后进近的空气条件下实现安全着陆。
