Mar 9, 2025 · 本文介绍如何建立 Simulink 数据字典，并关联 模型。 简单来说，数据字典的作用就是把一个模型用到的所有 数据对象 都统一放到一个地方管理起来。 Simulink中，数据对象包括信号对象、参数对象、枚举量、常量等。 也就是说，数据字典是很多个数据对象的集合。 举个最简单的数据对象的例子，新建一个 Simulink模型，其中有3个Gain模块，他们的放大参数相同，都是2。 如果要修改的话，就必须每个模块都打开来，把其中的2改成3，会很麻烦。 为了解决修改很麻烦的问题，可以在 Matlab 工作空间建立一个常量Gain_Const=2，再把Gain模块中的放大参数改成Gain_Const常量，如下图所示。 需要修改的时候直接把值改成3就行了。 Return value of data dictionary entry. 语法. 点击Apply，这时会出现一个询问窗口，问我们要不要同时关联Matlab工作空间的数据对象。 An object of the Simulink. 在弹出的窗口中选中Data Dictionary–>点击Browse…–>在弹出的路径中选中刚刚建立的demo.
