MATLAB/Simulink Application Research in the Dynamic System Simulation

本文基于一个海军防晕船训练装置——浪木的设计研究为例,介绍了MATLAB/simulink在动态系统仿真研究中的应用。首先基于系统结构进行物理模型构建,在此基础上,进行数学建模。并运用MATLAB/simulink软件,对存在阻尼的非小幅摆动系统进行系统仿真,得到了角位移、角速度随时间变化曲线,定量研究了振幅衰减关系。研究结果表明,MATLAB/simulink软件交互性好、形象直观、图形功能强大,能对动态系统进行有效的仿真研究,并可通过改变初始值,研究不同参量对结果的影响。

This article introduces the navy sickness training device --LangM MATLAB/simulink in the application of dynamic system simulation based on a u design, for example. First of all, a physical model based on system structure build, on this basis, the mathematical modeling. And using MATLAB/simulink software to system simulating for the large amplitude damping vibration system, get the angular displacement, angular velocity changing with time curve, quantitative research the relationship between the amplitude attenuation. The research results show that the MAT- LAB/simulink software interactive good intuitive, Image intuitive, powerful graphics functionsl, is effective in the simulation research of dynamic system, and by changing the initial value, study the influence of different parameters on the result.
