Design and Simulation on Aerocraft Auto Flatten-Out and Landing System

摘要:

简述了自动拉平系统基本工作原理,对拉平轨迹及指数拉平规律进行分析,之后设计了自动拉平耦合器和拉平着陆系统。在 MATLAB平台下,建立了自动拉平着陆系统结构图,并进行了大量仿真研究。仿真结果表明,所设计的自动拉平耦合器和拉平着陆系统参数合适、结构合理,系统工作稳定,并能满足预定的着陆参数要求。

Abstract:

Firstly, the basic principle of aerocraft auto flatten-out system was simply depictioned, level fly trajec. tory and exponential rule were analyzed. Secondly, the auto pullout coupler and auto changed level landing sys. tem were designed. Lastly, under the MATLAB platform, the structure diagram of aero auto changed level fly system was established. A great deal of simulation researches was done. Simulation results indicated that the structure of designed auto flatten-out system and it’s coupler was reasonable, and the control system was stabili. ty, and could meet demand for scheduled landing parameters
