中文摘要
      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,阵风干扰能够被抑制在工程允许的范围之内.
英文摘要
      This paper is concemed 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∞ con-troller is developed to guaranteethe 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 re-strained by using the new controller.
