摘　　要：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。This paper is concerned with the problem of airplane landing under the influence of wind disturbance. By combining the H ∞ optimization method with the structural perturbation approach of large scale systems, a hierarchical H ∞ controller is developed to guarantee the robust stability of the system. Since the system matrix is not invertible, a new method is suggested to get the perturbation matrix. The application to flight control shows that the influence of wind disturbance can be restrained by using the new controller.
