How to create Simulink model with multiple versions?

I have Simulink models that are different versions of a controller. The versions change static data, used throughout the model, and some blocks in the model. I am wondering if there is a way to create one Simulink model that can be changed between all these versions. A similar functionality exists in standard Simulink functions, such as with the PID Controller when you switch the form between Parallel and Ideal or the Logical Operator switching between AND and OR. Has anyone created or found similar functionality for making Simulink models with different versions?

I would suggest reading about Variant Subsystems. They are intended for doing exactly that.

Hi Les, thanks for bringing the variant subsystem to my attention. Do you know if there is a way to change which varient the model uses after compiling the model at the beginning of runtime?

@Tiernan Moore

I'm pretty sure it is possible to select the desired variant programmatically (e.g., in a script that initializes things and runs the model with the sim() function).

It has been years since I did any work with Simulink, so I don't remember off the top of my head how to do it. Seems like you set the variant selector (probably not the right name for it) to be a workspace (model or base) variable and set that in your initialization script.

Sorry I'm not more help.

If my answer addressed your initial question sufficiently, would you please Accept it?
