摘要: 研究自动着陆过程中的非最小相位飞机对象的轨迹精确输出跟踪问题.分析了自动着陆过程的特点,采用稳定逆控制方法并结合反馈控制器设计了大型运输机的自动着陆控制律.稳定逆根据对象模型产生期望控制输入和期望状态轨迹,反馈控制器处理飞机对象参数不确定性及外界干扰.基于飞机对象的相对阶,设计了满足舒适性的光滑进场着陆期望轨迹.仿真结果表明,自动着陆控制律具有精确跟踪能力,自动着陆过程满足美国联邦航空局III类精密进场着陆要求,并且飞机内部动态稳定有界.

Abstract: The problem of trajectory exact output tracking of non-minimum phase aircraft plant in automatic landing process was studied. The characteristic of aircraft automatic landing process was analyzed. Combined with a feedback controller, the stable inversion control method was adopted to design the automatic landing control law of a commercial jet airplane. The stable inversion calculated the desired control input and desired state trajectory according to nominal aircraft plant model, and the feedback controller deals with the parameter uncertainties of aircraft plant and external disturbance. Based on the relative degrees of aircraft plant, the smooth landing trajectory was also designed to satisfy the comfortable requirement of commercial jet airplane. The simulation results showed that the automatic landing control law had exact output tracking ability, and the automatic landing process met federal aviation administration (FAA) requirements for the category III precision approach landing. The internal dynamic of aircraft was stable and bounded.
