Hello. How do you know when you cannot apply PID-controllers to a system? Have you had an experience where you first thought that a PID-controller might work but eventually find it impossible? How would you decide?

Not at first. I have learned over the years that if it doesn't work in theory it doesn't work in the real world.You seem to be a textbook guy, so an example outside of the noise reason, it is easy to visualize.
None, in reality. There may be systems where only one pole is dominant. Only those systems can be tuned using a PI controller and only if one doesn't excite the higher order poles.BTW... A "plant" with "1" pole? What real life plant has only "1" pole?
