H_∞控制理论在飞机阵风着陆控制中的应用

Application of H_∞ theory in design of aircraft landing control

飞机在着陆过程中 ,极易受到阵风干扰。通过设计 H∞ 状态反馈控制器 ,来抑制阵风干扰 ,并解决控制输入过大等问题。仿真结果表明 ,所设计的飞机 H∞ 状态反馈控制器能满足自动着陆要求 ,并且能有效地抑制阵风干扰和避免控制输入过大等问题。由于 H∞ 控制理论自身的优点使其在阵风着陆控制中效果良好。

The automatically landing of an aircraft is prone to be disturbed by gust. This paper studied and discussed the method of H ∞ state feedback controller to restrain that disturbance of gust. The simulation results indicate that the new design can satisfy the design specifications, and it restrains that disturbance of gust and prevent the emergence of input extremity. Because of the advantage of H ∞ controlling method, it performs a satisfying results in the landing control with gust.
