Obtaining the model topology from a Simulink model

女生的网名这么多〃 提交于 2019-11-30 17:40:20
问题 I would like to create a structure in Python which represents a Simulink model. I am aware of at least two ways of doing this - by parsing an ".mdl" file, or by using Matlab's api for communicating with the model. Can you recommend good libraries or APIs for doing this? In particular, I need to perform some processing on a Simulink model and I would like to do it in Python. Also I don't want to be constantly communicating with Matlab for doing this (so that I can release the floating license)

How convert simulink files to XML

我的未来我决定 提交于 2019-11-30 16:36:26
I need convert an Simulink file (.mdl) to an XML file, after any searches i'm not found any content to help me with this problem. You'd know some way or ready solution for this in Java? Starting in R2008b, you can export an .mdl file to an .xml file using save_system , >> save_system('model.mdl', 'model_xml.xml','ExportToXML', true); I know of no easy solution. However, there are a couple of libraries in Java that apparently can parse simulink files. They should be sufficient to give you an in-memory representation, and you could then use an XML binding to produce passable XML. 来源: https:/

How to export simulink data to workspace during simulation?

本秂侑毒 提交于 2019-11-30 04:36:51
问题 I want to retrieve the data from simulink during simulation , and use serial network function to send these data to another program. Because I need to use another program to do some tricks and send command back to simulink, so I have to get data from simulink during runtime so that another program can make the right command. I've tried using To Workspace block to export the data. However, I can only got value in the very beginning of the simulation. And I've also tried using scope and change

Slowing Down Simulink

爷,独闯天下 提交于 2019-11-29 16:30:34
I have a simulation that runs in Simulink with input base on a set of 5000 samples. With my simulation time set to 5000 steps, the model runs (in about 2 seconds) and then I get the results. Is there a way I can change my model so that it runs more slowly and I can see the results change as the simulation progresses? I haven't touched Matlab or Simulink for about 12 years so assume I'm a noob. I'm sure the information is there somewhere in one of the manuals I just don't know what to look for :-( TIA Mark Yes, there are various utilities to slow down the execution of a Simulink model on the

Matlab 2013b generated code produces Undefined symbols for architecture x86_64 error in mex

穿精又带淫゛_ 提交于 2019-11-29 15:47:08
I have a C-Code generated by the Simulink Coder that I need to use in a C S-function. This may sound a bit strange but I need this Code to be executed multiple times within the s-function before writing the outputs of the s-function (it's an evolutionary algorithm that needs to simulate a prediction for a lot of individuals before evaluation and ranking...but those details do not really matter). The Problem is that I seem to have a problem with the 64bit instruction set when trying to mex my code. I am taking the generated erg_main.c as an example on how to interact with the generated code: /*

Deployment of Simulink Models

扶醉桌前 提交于 2019-11-29 15:29:50
I have been trying to find out how to deploy a Simulink model. There are possibilities and problems as well. If I use Simulink Coder how can I find the generated code on my computer? Where is it saved as a file or package of files? Can we deploy Simulink as .NET Assembly? If we can, where can I find a detailed documentation about it. Is there any other way to use my Simulink model standalone? Thank you for any effort. By default all the code gets placed into a folder, in the current directory, called ModelName_CodeTarget, where ModelName is the name of your model and CodeTarget is the

3rd-order rate limiter in Simulink? How to generate smooth triggered signals?

First for those, who are not familiar with Simulink, there is a imaginable outside-Simulink partial solution: I need to create a vector satisfying the following conditions: known initial value a1 known final value a2 it has a pre-defined step size, but the length is not pre-determined the first derivative over the whole range is limited to v_max resp. -v_max the second derivative over the whole range is limited to a_max resp. -a_max the third derivative over the whole range is limited to j_max resp. -j_max at the first and the final point all derivatives are zero .

Input data to Simulink from workspace

…衆ロ難τιáo~ 提交于 2019-11-29 11:28:42
Hello anyone does know? I have data(myData) from matlab workspace. And in matlab simulink I have to do control system with regulator.First how to put data(myData) to simulink model input,and I want to show in graph two value(myData and regulator). You can use the From Workspace block to read the data( lets say simin ) from the worspace. The variable simin should a structure with following fields: signals : values : A column vector representing data. Description : A string describing the data (can be empty) time : The time stamp, Its a column vector, with dimension same as that of the signals

How do I provide input to a Simulink model without placing it in the workspace

白昼怎懂夜的黑 提交于 2019-11-29 03:06:18
问题 I have a Simulink model that is currently being run from a script (i.e. not a function). The script writes variable values to the MATLAB workspace, runs the model simulation (which uses these values), and then the model writes additional values to the workspace. If I try to convert the script into a function (i.e. by placing function [output] = runSim() at the top of the file) then Simulink complains that it doesn't know about the variables, presumably because they are not in the MATLAB

simulink中定义结构体信号线

浪尽此生 提交于 2019-11-28 07:29:09
在simulink中,有需要用到Sfunction函数,Sfunction函数的输入为结构体,就需要外部跟Sfunction函数的连线也为结构体,这样就需要定义simulink中信号线也为结构体类型。 1.定义bus总线 1.在simulink界面中,点击view->model explorer->base workspace 2.在model Hierarchy窗口栏选中base Workspace.点击Add->simulink bus->Launch Bus Editor 3.选中BUS信号,在右侧修改信号名和类型。点击工具栏里面黄色图标,添加成员变量 4.在simulink中使用BUS Creater将信号线组合在一起 5.双击BusCreater,在output data type选中上面定义的结构体名字就可以了 至此就OK了 来源: https://www.cnblogs.com/xingjian92/p/11399154.html
