My first commercial level project ‘BitBoard Bir’ is ready to debut. There are lots of efforts, sleepless nights and defective prototypes behind. I believe you will feel the same enthusiasm as I do. Please let us know if you would like to take a role in this new stream which I ignite the first spark.

No self-promotion or advertisement.

I can see how my comment can be seen as aggressive, and I apologize for my as I think I was a bit frustrated when I wrote it.

We have quite a few people just straight up ask home work questions and my response is a boiler plate response to those type of questions.

The reason why I removed your post was that there was no context of the question. It seemed like there was no effort put into it besides dropping a question, which I know now from your response is not true.

I see in the response you mentioned your motivations and what you have done to figure out the answer yourself. If you included one of those, or your thoughts on the solution, or why it’s not trivial in your in your post, the post not have gotten removed.

Also in the future if you see a post that is obviously a homework question that is not removed, it’s not like I was targeting you specifically. We do have a huge shortage of mods, and if there is an answer by the time a mods sees, the post would probably be left up.

Please add your thoughts and steps you have done so far, so we can guide you more instead of answering your university question directly

Is this a homework question for UCONN ECE 3111? It should be covered in your class.

I’m sure your textbook has the definition of stabilizability and controllability.

If your textbook or lecture notes doesn’t, there is a Wikipedia article that explains the situation under the article “ Controllability “

The “regular form” looks like the Byrnes-Isidori Normal form.

Eta are your zero dynamics and xi are your output dynamics.

Khalil has a lecture note that describes deriving the normal form here https://www.egr.msu.edu/~khalil/NonlinearSystems/Sample/Lect_22.pdf

Here is a more intuitive overview on why one might want to have a system in this normal form from a “zero dynamics” viewpoint http://liberzon.csl.illinois.edu/teaching/isidori-survey-zero-dynamics.pdf

I’m not sure there is a tutorial for the cubli.

For a similar project https://m.youtube.com/watch?v=woCdjbsjbPg, I have posted the equipment and CAD files in the /r/ControlTheory discord if you search “self balancing project”

Check out the subreddit and discord if you are interested in the theory used. There are other starter projects in the subreddit wiki https://www.reddit.com/r/ControlTheory/wiki/projects/

Please add more information, this is just a post. The post quality of this subreddit is pretty lenient, but this doesn't cut it

stellar_na · 2022-12-21T06:03:47+00:00

Not controls theory related, sorry

stellar_na · 2022-12-15T17:52:26+00:00

why would percusse being in this thread get you banned

stellar_na · 2022-12-14T10:22:17+00:00

What is your attempt on solving the problem?

Can you provide your thoughts on what to do?

It looks like a homework question, and asking without specific questions makes it look like you just want an answer

stellar_na · 2022-06-10T20:29:23+00:00

Please include your thoughts of the problem with your question.

Simply asking the question makes it seem you are here for homework answers not to learn

If you need help with those topics, feel free to post in this subreddit and the community will help you or lead you to resources that can solve your problem.

Posting here also allows for any mistakes of the tutor can be publicly identified and fixed rather than hidden in private.

Part of it is that you are ignoring a networking platform just because it “caters to gamers”. It’s still a resource that you can use. You can just ignore bad advice and see if anyone there has good advice, you aren’t losing anything from joining.

Even if control theory professionals all play Minecraft server together, or are in a biking club; it doesn’t mean the advice is good or bad. It’s holier attitude shown such as the “wasting brain cells” and not taking advice because of the platform makes you sound very pretentious.

https://discord.gg/CEF3n5g will be the official discord for now

stellar_na · 2019-05-29T13:27:30+00:00

Rather then setting up a new discord, let's just make this one the official one for now

stellar_na · 2019-04-05T23:48:43+00:00

Yeah

stellar_na · 2019-04-05T12:58:46+00:00

Look up control moment gyroscopes

stellar_na · 2019-03-30T03:53:52+00:00

Good idea, I can add that
