How to dynamically change a parameter in a Matlab simulink model using a knob

In this video I show you how to add a knob into your Matlab simulink model and how to connect it to a part of your model. Using a knob you can dynamically change a parameter while the simulation is running and see the influence of that dynamic on the response of your system.

thanks, just what i needed. go example to

Hi, how do you change the time of simulation?, i mean the real time of the simulation, how can you take 1 second of the simulation to take i.e 2 seconds on real time? Thanks!, great video

Hi, I have made a simple example how to run your simulation in real-time, this is not exactly what you asked for, but this is more useful I think. ua-cam.com/video/I33XalLxFsA/v-deo.html

Thank you it helps really

[@shoaibamjad4599]

how to find this switch in matlab that you use in your video

[@yimintan4927]

What if we want to change the parameters in the RL part?

thanks

Why cant I used the Dash Board tools to change my parameters during simulations

[@growingcrystals1133]

The same problem. Maybe you've found solution?

[@growingcrystals1133]

For me it works to add block "Real time simulation" into the project. (with sample time 0.001 in settings). But maybe there is another way

[@gimon2233]

@@growingcrystals1133 Because the timing is not in sync with the Simulation. I used aerospace add in to introduce a block that will let me change the parameters realtime. I forgot the name of that function block sorry.
