本文介绍了一个火箭模型，并讨论了使用变结构方法来重新建模关键部件的优点。两个版本的模型都在Modelica中实现，并使用Dymola作为仿真环境进行仿真。DySMo框架，它支持在常见的仿真环境中的变结构模型的仿真，被用来促进重新设计。变结构方法的一般好处，并在火箭模型的基础上，我们提出，仿真时间和数据量的仿真可以减少，同时保持仿真结果的准确性。变结构建模，仿真速度，数据简化，降低方程刚度，火箭发射
This paper introduces a rocket model and discusses the advantages of refining it using a variable-structure approach to remodel critical parts. Both versions of the model are implemented in Modelica and were simulated using Dymola as simulation environment. The DySMo framework, which supports the simulation of variable-structure models in common simulation environments, was used to facilitate the redesign. The general benefits of the variable-structure approach are presented, and on the basis of the rocket model we present that simulation time and the data volume of the simulation can be reduced while maintaining the accuracy of the simulation results. variable-structure modeling, simulation speed, data reduction, reduce equation stiffness, rocket launch
