Simulink-以编程方式指定外部输入 [英] Simulink - programmatically specifying external inputs

问题描述

我想以编程方式调整Simulink的一些参数，即指定外部输入和初始状态. 数据导入/导出上的Mathworks帮助文档. a>展示了如何在视觉和程序上做到这一点.显然，对于外部输入，我需要将LoadExternalInputs指定为'on'；我想通过ExternalInput到[myTimeVar, myInputVar]覆盖默认的外部输入，如该链接中所述.

I would like to adjust some Simulink parameters programmatically, namely specifying external inputs and initial state. The Mathworks' help document on Data Import/Export shows how to do so both visually and programmatically. Apparently for external inputs, I need to specify LoadExternalInputs to 'on'; I would like to override the default external input via ExternalInput to [myTimeVar, myInputVar], as documented in that link.

尝试运行命令

sim('mySim', 'LoadExternalInputs', 'on', 'ExternalInput', [myTimeVar, myInputVar]);

产生以下错误消息:

block_diagram'mySim'中参数'ExternalInput'的设置无效

Invalid setting in block_diagram 'mySim' for parameter 'ExternalInput'

如果不应该在sim()调用中指定我的外部输入，我应该在哪里做?我对如何指定输入和状态感到很困惑.

If I'm not supposed to specify my external input in the sim() call, where am I supposed to do it? I'm quite confused as to how to specify my inputs and states.

推荐答案

ExternalInput参数必须是字符串，请尝试以下操作:

The ExternalInput parameter must be a string, try this:

sim('mySim', 'LoadExternalInputs', 'on', 'ExternalInput', '[myTimeVar, myInputVar]');
