Ok, if we look at a basic Linear Time-Invariant Open Loop transfert function H(s) in the frequency domain. Then the poles are the values for s for which H(s) is infinite, right?
So if H(s) is infinite than the time domain output for t->infinity is also infinite too right? (If not, why not?)
But how is that possible? If f.e. s = -3+2i. Then the the output should die out!
In other words, what is the meaning in the time domain of a pole in the frequency domain??

This is more /sci/ than /diy/ I would say, but whatever. Poles are points in the complex plane Which are the zeroes of the denominator of H(s). H(S) is not defined a these points, but I guess you could say that H(s) is infinite if evaluated at a pole.
The time and freq domains are linked by the Laplace transform, and what matters is the position of the poles (poles with positive real parts make a system divergent in the time domain).
Look up some control systems theory on wikipedia or ask /sci/ to give you some reference material to get a better understanding

I think you lack basic theoretical knowledge that some 4chan posts won't be able to explain to you

Watch the youtube lectures by brian douglas on control systems, from his first video until his last. Trust me, it is the best thing you will do in control engineering. He will tell you the answer to your question as well, next to things you might not have known.
Just search for "Brian Douglas" or "Control System Lectures" on youtube and you will find him.

I think this applies perfectly well on /diy/ as long as it is for a do it yourself project. Of course seeing from the way the question is asked, it is more appropriate for /sci/, but then again, have you seen it recently? Horrible board and degraded very badly in the last 2 years.
Also, I like to see something with at least a bit of substance on /diy/ once in a while instead of the endless 'should i buy x tools' threads.

That feel when i hated my controls class. Electrical engineering is WITCHCRAFT!

Circuits classes maybe, but I feel like control systems had a lot of theory to ground it quite well. Fuck RF circuits though

agreed, that shit is the real
