Setting/Tuning parameters of a Simulink model in Realtime

I am currently working on a desgin of a GUI for a Real-time Simulink model. The problem I am facing is that in real-time I have no access to all the parmeters in my model like the resistance or capacitance.

I simulated a simple model for illustration and I attached the screenshots.

In addition , I also tried to use instrument panel in Simulink Real-time explorer to tune the parameters in realtime but I had the same problem which is the limitation of the parameters I can tune.

Answer 1

[Diego Kuratli]

Instead of the Resistor and Capacitor blocks, use Variable Resistor and Variable Capacitor.

Answer 2

I believe Diego's suggestion will help.

I would also suggest to use Simulink Parameter variables inside the Model workspace and change those instead of the values inside the blocks directly.
