摘要
以某型号运载火箭为研究对象,建立飞行仿真系统各功能模块的数学模型,并基于MATLAB/Simulink仿真工具对这些模型进行相应的仿真。采用Simulink子系统及其封装技术,把大的模型分割成几个小的模型系统,最终完成飞行全过程的仿真。以一、二级飞行段仿真为例进行分析,仿真结果与试验数据较为吻合,验证该仿真模型正确有效。
Mathematical model of flight simulation system is established based on a certain type launch vehicle. The models are simulated based on MATLAB/Simulink. The complex models are divided into several smaller system, and the flight ion is realized at last. Taking simulation of first and second flight phase as an example progress analyzed, the simulation results are consistent with the tested data, which proves that the model is accurate and valid.
