空天飞机再入GNC一体化建模与仿真方法

Integrated Modeling,Design and Simulation Platform for Aerospace Vehicle Entry Guidance and Control

集建模、制导控制律设计与数学仿真分析于一体的建模与仿真平台是进行空天飞机再入制导导航与控制系统(Guidance,Navigation and Control,GNC)研究的有效手段。提出一种基于Matlab平台和STK软件的空天飞机再入GNC一体化建模与仿真平台方案。基于Matlab平台进行二次开发,建立空天飞机建模工具,开发制导控制律辅助设计工具和数学仿真程序,利用STK软件进行结果的可视化仿真,为空天飞机再入GNC系统研究提供有效的建模、设计与仿真分析工具。

Integrated modeling,design and simulation platform is a useful tool for aerospace plane guidance,navigation and control system design.A simulation platform based on Matlab and STK was proposed.Modeling and simulation tools were developed using Matlab software,and GNC computer aided design tool was developed in this design environment.STK was used to visualize simulation results.The proposed platform provides an effective way to model,design and simulate entry GNC system for aerospace plane.
