着舰导引系统 H_∞ 控制器设计

Design of an Automatic Carrier Landing System Using H ∞ Synthesis

舰载机着舰导引误差的最大来源是舰尾气流扰动。为抑制气流扰动，提高舰载机自动着舰导引的精度，本文将Ｈ∞控制方法应用于着舰导引系统设计，将导引系统性能要求转化为对Ｈ∞控制分析模型的结构及权阵的选取。仿真表明，用Ｈ∞控制方法设计的着舰导引系统能满足着舰要求，并十分有效地提高了导引系统着舰精度及抗扰动的能力。

A new design methodology, in which the typical single input/output design specifications were translated into the weighting functions of an H ∞ ouput feedback synthesis problem is used to design an automatic carrier landing system. The objective of the design is to improve the automatic carrier landing system′s (ACLS) path precision under the worst case condition of vertical gust during carrier landing. The simulation results indicate that the new design can satisfy the design specifications.
