MATLAB: How to create tunable parameters for a standalone FMU Export

exportexport fmufmifmuMATLABSimscapesimulinksimulink compiler

Hello,

I want to export a standalone FMU from a Simulink model. I have already managed to export a FMU with the Simulink Compiler but I dont know how to create tunable parameters for this standalone FMU. I tried to define them as parameters in the model explorer, but they dont show up when importing the FMU into a FMU Block.

The model is made of mostly Simscape blocks and the tunable parameters should be the parameters in the Simscape Stepper Motor Block.

Thanks in Advance!

Hi David

You need to set in the Simscape Preferences (MATLAB user pane) the option Show Run-time parameters on.

https://se.mathworks.com/help/physmod/simscape/ug/about-simscape-run-time-parameters.html?searchHighlight=simscape%20run%20time%20parameters&s_tid=srchtitle

Then you should see that simscape parameters for the stepper motor have 2 options: Compile-time and Run-time. Select the second for given parameters. Once the FMU is created, these shall appear upon double clicking the block.

Hope this helped out Cheers Juan

Please follow these steps to make some of the model parameters visible in the FMU Block Parameters window:

Open the Model Explorer.
Make sure that the parameters used in the model are stored in the Model Workspace.
Check the box 'Argument' for those parameter you wish to be visible in the Parameters tab of the FMU block.

Now you can save the model and then retry the FMU Export.

Finally, the commands to run in order to start the automation server from a Windows Command Prompt are:

cd C:\ProgramData\MATLAB\SupportPackages\R2018b\toolbox\shared\ fmu_share\script
fmu-matlab-setup.cmd
start 1

MATLAB: Error using Simscape Eletrical – Boost Converter component

I was able to reproduce the problem. It seems that for the Boost Converter block there was a build issue. If you change the default value for any parameter in both Boost Converters and press apply the error will dissapear. Moreover, I've noticed that you need an Electrical Reference connected to the ref- terminal of the Controlled PWM Voltage.

Hope that helps.
