Manipulating Parameters real-time in SpeedGoat

Hello,

I would like to have the ability to manipulate parameters (workspace or otherwise) when my simulation is running on a Speed Goat xPC. The requirement is to manipulate these live to support interface debugging with another PC.

Is there a standard procedure or accepted method for doing this?

Hi Leonid,

Do you mean the parameters of the various blocks in your Simulink model? If so, there are several convenient ways to do this:

1. Tune parameters using MATLAB command lines
2. Tune parameters using the Simulink model as a user interface to the real-time application running on your target machine
3. Tune parameters using the Simulink Real-Time Explorer (note that this version of the Explorer is deprecated in R2020b, so it might not be the best long-term solution)

In case you decide to go with the first approach, note that you can integrate these commands in a custom UI that you can create using App Designer.

Best,

Dimitri

I am currently running real-time simulations in MATLAB Simulink, and I would like to modify certain parameters while the model is running. For example, I would like to manipulate the values of some Constant blocks during execution.

When I configure these parameters as tunable in the model settings, the displayed value of the block changes as expected. However, the signal output from the block continues to hold its previous data, without reflecting the new value. Additionally, when I attempt to apply changes directly from the MATLAB workspace, the modifications are not accepted. Is this same problem with yours? If you could solve, could you share solution with me?
