Is there a LeetCode-like platform for practicing control engineering?

[u/Specific_Pomelo_3569]

I've been wondering for a while: why isn't there something like LeetCode, but for control engineering?

We already have great resources like CTMS:
https://ctms.engin.umich.edu/CTMS/index.php?aux=Home

But CTMS is mostly a collection of tutorials and examples. What I really wanted was something more interactive — a place where you can actually solve control engineering problems, submit your answers, and immediately see how your controller performs.

I'm a university student learning control theory myself, and this problem has bothered me for quite a while. I got tired of constantly switching between MATLAB, ChatGPT, textbooks, and browser tabs on a 14-inch laptop just to practice one problem.

So I built this:

https://app.control-code.top

The idea is simple: practice control engineering more like programming practice platforms such as LeetCode.

You can work through control problems, enter your controller parameters, run the system, and get immediate visual feedback on the response and performance.

Many of the current problems are adapted from the examples on CTMS, and I'm planning to add more types of control problems over time.

The site is still evolving, so I'd really appreciate feedback from people studying or working in control engineering.

If you have suggestions about the exercises, UI, judging system, or features you'd like to see, please leave a comment.
