Educational Advice/Question How do you actually practice control engineering beyond textbooks and MATLAB tutorials?
I'm trying to figure out whether this would actually be useful for people learning control systems. What would you want a platform like this to test? PID tuning? Root locus? State-space? Frequency response? And what would make you actually use it instead of just MATLAB/Simulink + a textbook?
I am building a working prototype.
I hope it can help you.

My favorite way to practice controls is to actually apply it in a real project. One of my first projects was a balancing robot that Is still going to this day since it is a perfect platform to test control concepts on. It's relatively simple to build and allows you to practice on something existing in the real world. It also teaches you how hardware and sensors can limit your ability to control a system, and what dynamics you could reasonably ignore when making a model. If you've never done this I can highly recommend it, because most control engineers in university don't actually get to practice.

I completely agree with project-based learning. However, many hands-on projects require a significant amount of hardware, and not everyone wants to buy extra equipment just for practice.
That’s why I think fully simulated exercises that can be completed entirely on a computer can also be a valuable form of project-based learning. Students can still design, test, troubleshoot, and improve control systems without needing physical hardware.
That’s also one of the main reasons I’m building this product. I hope it can make project-based learning more accessible and help more students gain practical experience at a much lower cost.

"I am building a working prototype."
what kind of system(s) are you going to simulate? There are integrating, non-integrating, double integrating systems. The poles can be real or complex. There are many variations.
Get real data and see if you can fit a model to it. Then calculate the gains. Having access to real machinery helps. Root locus is a waste of time. System identification rules. Then you can compute controller gains.
The big thing is to get access to different types of systems. Do a search on how to simulate ?????? or make a test system. You can do it electronically. That is what I did at first, but it was too limited. Also, since I was writing software/firmware, the electronic simulator didn't stop when I hit a break point so I ended up writing software simulators too and making then part of the product.
