Design of a Robust H_∞ Controller for Automatic Landing System of an Aircraft

利用鲁棒 H∞ 控制理论设计了某型飞机的自动着陆系统。讨论了飞机自动着陆过程的要求 ,分析了系统中可能受到的干扰 ,之后建立了 H∞ 控制问题的系统模型。针对飞机着陆时的要求设计了一种鲁棒 H∞ 控制器以抑制阵风的影响。仿真结果表明 ,所设计的控制器对自动着陆时的干扰具有较好的抑制能力 。

This paper mainly designs a robust H ∞ controller for an aircraft. The special requirements for the autolanding process are taken into account.The probably encountered disturbances and errors are analyzed.The system mathematic model for the H ∞ control problem is established in this paper. A kind of robust H ∞ controller is designed to make the needs of the special requirements. Numerical simulation presents the designing procedure of the proposed controller and shows that this kind of controller makes disturbance attenuated, and makes the autolanding system properly follow the expected trace and satisfy the landing requirements.
