摘要
运载火箭的时域仿真软件如果采用C语言开发、工作量庞大、周期长,Matlab包含仿真平台Simulink,它拥有丰富的函数模块库,无需单独开发界面,无需为实现积分算法而专门编写程序。结合实例,介绍如何利用Simulink搭建火箭姿态控制系统时域仿真模型,其中重点分析如何采用S-function实现箭体模型,如何解决时变参数输入、多维微分方程计算、合理加快仿真速度等难题。开发过程与开发结果充分表明,这种方式具有开发速度快、界面直观、通用性强等优点。
It is burdensome and time-consuming to develop a software for time domain simulation of a launch vehicle by using C Language.Instead,The software Matlab provides a platform called Simulink where there are enrichment common function libraries.Neither does it need to develop alone an interface between man and machine,nor to develop special programs in order to perform the integral calculation.Based on an example.The development of software for time domain simulation of launch vehicles with Simulink is introdu...
