Hey all, Im using a simscape model as a plant for a feedback control problem, and the crux of my issue is i want to adjust the controller then run the simulation in a loop. Not adjusting the simscape plant just the controller, but recompiling the simulink model is way too slow even using rapid accelerator mode. And fast restart doesnt allow the controller model to be changed. I was wondering if there was a way to have the simulink simscape model be composed of just the plant, and apply it to the feedback loop in the matlab code. Or some way to allow me to run the simulink model and be able to change the controller while still using the fast restart and not recompiling the model. Thanks

Hi Leo,
You can apply the Fast Restart Mode to the plant model only, by using the command:
>> set_param('plant', 'FastRestart', 'on');
In this way, if you are using the model references properly, you will be able to adjust the controller, and the plant model will be set to the Fast Restart Mode.
In case you want to update the plant model, set the Fast Restart Mode to ‘off’ again.
Also, set the plant model reference to Accelerator Mode / Rapid Accelerator Mode so that it becomes even more faster.

Hey thanks a bunch for that, I'll give it a try at some point to fully confirm, I put that on the backburner. But seems like that puts me on the right track. Big thanks!
