Chapter 7: Introduction to Simulink
Simulink 初步(Primer of Simulink)
MATLAB Simulink是一个动态仿真系统,用于对动态系统进行仿真和分析,预先模拟实际系统的特性和响应,根据设计和使用要求,对系统进行修改和优化。
Simulink提供了图形化用户界面,只须点击鼠标就可以轻易的完成模型的创建、调试和仿真工作,用户不须专门掌握一种程序设计语言。
Simulink可将系统分为从高级到低级的几个层次,每层又可以细分为几个部分,每层系统构建完成后,将各层连接起来构成一个完整系统。
模型创建完成后,可以启动系统的仿真功能分析系统的动态特性,其内置的分析工具包括各种仿真算法、系统线性化、寻求平衡点等。仿真结果可以以图形方式在示波器窗口显示,也可将输出结果以变量形式保存起来,并输入到MATLAB中以完成进一步的分析。
Simulink可以仿真线性和非线性系统,并能创建连续时间、离散时间或二者混合的系统。支持多采样频率系统。
