文章分析并建立了基于能量的大型飞机纵向自动着陆控制系统.利用特征结构配置方法(Eigen structure Assignment,EA)设计了飞机俯仰姿态保持内回路和控制增稳系统,针对发动机推力回路复杂模型不确定性,用定量反馈法(Quantitative Feedback Theory,QFT)对推力回路进行了补偿设计,以总能量控制为核心控制结构,协调控制飞机升降舵和油门杆,实现飞行速度和飞行航迹的解耦,进而完成定坡度下滑和拉平过程.仿真表明所设计的自动着陆控制系统满足飞机精确进场和着陆要求.%Aim. The introduction of the full paper reviews some papers in the open literature, mostly in Chinese,and then applies total energy control to achieving its feasibility. Sections 1, 2 and 3 explain our design and give simulation results to verify its feasibility. The core of section 2 consists of: ( 1 ) we utilize the Eigen-structure assignment (EA) method to design the pitch inner-loop of aircraft and its control augmentation system; (2) taking both the uncertainty and complexity of aircraft engine control loop into consideration, we use the quantitative feedback theory (QFT) method to perform the compensation design of a thrust loop. The core of section 3 consists of:(1) we take a B-737-100TSRV aircraft as a numerical example to design its longitudinal landing control system;(2) we apply total energy control to coordinating the elevator of aircraft and its thrust commands, thus implementing the decoupling of flight path from speed control, glide-down and landing; (3) we perform the simulation of our aircraft longitudinal automatic landing control system; the simulation results, given in Figs. 4 and 5, and the analysis of Fig. 5 show preliminarily that the landing control system is feasible for decoupling the flight path of aircraft from its speed control and thus achieving precise landing.
