本文对阵风干扰下的飞机着陆控制问题进行了研究，将Ｈ∞方法与大系统结构摄动递阶控制思想相结合，给出了具有鲁棒稳定性的递阶Ｈ∞控制器．在求解摄动矩阵时，针对系统矩阵不可逆的情况，提出了一种摄动矩阵的计算方法．对某型飞机的应用仿真结果表明，采用本文所给的递阶Ｈ∞控制器，阵风干扰能够被抑制在工程允许的范围之内 In this paper, the problem of aircraft landing control under gust disturbance is studied. The H∞ method is combined with the theory of perturbed and hierarchical control of large-scale system structure, and a hierarchical H∞ controller with robust stability is given. In solving the perturbation matrix, aiming at the irreversibility of the system matrix, a method of calculating the perturbation matrix is ​​proposed. The simulation results of a certain type of aircraft show that the gust disturbance can be restrained within the range allowed by the project by using the hierarchical H∞ controller given in this paper
