针对传统建模方法建模效率低问题,将Modelica语言应用于某弹道导弹飞行仿真。简要比较了Modelica语言平台与Simulink,介绍了Modelica的基本建模方式,高效实现了系统数学模型到仿真模型的转化,解决了建模过程中弹道导弹的多阶段飞行切换问题,对导弹参数进行了有效管理,在可视化建模环境下通过拖拽图标搭建系统,过程快速直观,模型层次分明,仿真结果得到验证。

Focused on the problem of low efficient of traditional modeling method, the Modelica was briefly introduced and compared with Simulink, the typical modeling modes of Modelica were expounded. Conversion from mathematic model to simulation model was realized, and switch proposition of multi-phase flight of ballistic missile during modeling was solved, and parameters of model are managed effectively. The construction of missile system model was realized by dragging model icons under graphics modeling environment. The hierarchy of model was clear and the simulation results were verified. Some fine characteristics of Modelica were displayed in this contribution and it is of certain reference value for developing homogenous model using Modelica.
