MATLAB: Generate DLL from Simulink model

dllEmbedded Codermatlab coderreal time workshopsimulinksimulink coder

Hallo everybody,

I am about to start working on an interface between Simulink modules and GH BLADED, software tailored to simulate the dynamic behavior of wind turbines. Within Simulink, I plan to develop some control strategies. This control model should be then ported as DLL to BLADED and actually command the reaction of the turbine to external inputs.

I'd appreciate knowing if any of you may address me to the easier procedure to generate DLL out of a Simulink model. At the time of writing, I do not have a clear idea about the best way to go.

Perhaps, it would be an option to generate a .tlc file, suited only for BLADED, exactly as it happens with LabView (but LabView already supports such a tlc file, BLADED so far does not).

I really thank you in advance for considering my request.

Kindest regards, FPe

You can use ert_shrlib.tlc if you have the Embedded Coder product to generate generic DLLs from your Simulink model. The relevant documentation is here: Shared Object Libraries.

You can certainly do this with your Simulink model.

Simulink Coder (formerly Real-Time Workshop) allows you to generate C/C++ code from your Simulink model, as you know. Your options from there are

1. Integrate that code directly with your C# application and build them together. This is a common approach. It is fairly easy to get all of the Simulink dependencies using a feature called packngo:

The code generated from the Simulink model provides interface functions such as

<modelName>_initialize()
<modelName>_step()

which allow you to initialize and step through your model. It is then the C# application's responsibility to call them at the correct time.

2. Build the Simulink generated code into a shared library and then have your C# application use the shared library. There seems to be a way to do this but I must confess that I've never done it myself.

Here's a doc link for ya though. It seems to require the Embedded Coder product as well.

Hope this helps!

MATLAB: Difference between Simulink Coder and Embedded Coder

Both Simulink Coder generate C code from Simulink models, and both of them can put that C code in a C++ wrapper to be effectively integrated with other C++ code.

The main difference between these products is:

Simulink Coder generates code with the purpose of the model being able to run standalone without a MATLAB license, or to verify the behavior of the generated code on a host computer.

Embedded Coder generates readable code that can be much more finely configured, customized, and optimized through various settings and constructs. Embedded Coder also provides support for automatically building the generated code on embedded systems (hence its name).
