摘　　要：飞机自动着陆系统是现代飞行控制系统的重要组成部分。为解决飞机的精确定位问题,本文采用非线性逆系统方法对飞机自动着陆系统进行控制。通过状态变换输出与输入间的线性关系使飞机原非线性方程反馈线性化,使原非线性系统解耦为一个一阶和一个二阶线性系统,并设计了神经网络控制器。仿真研究结果表明,基于非线性逆系统的神经网络滑模控制器方法能较好实现飞机自动着陆系统的有效独立控制。Auto landing system is an important part of modern flight control system. In the paper, to solve the problem of the aircraft positioning accurately, a control method based on inverse system theory has been presented for aircraft auto- matic Landing. The nonlinear equation of aircraft is linearzed by state transforming differential relationship between input and a new input, and the nonlinear system is decoupled to a one order linear system and a two order linear system, then the Neural Network Sliding Mode Variable Structure controller is designed. Furthermore, the feasibility of the method is validated by the results of simulation.
