hi, in a purely integral controller, why does the height of the overshoot/undershoot decrease continuously? can someone pls help with this? I cant find anything on the internet or here.

(this question is related to pid controllers)

@insipidintegrator Decrease continuously as a function of what? Are you asking why the overshoot decreases with time (and eventually settles)?

yes, i meant to ask why the peak values of successive over/undershoots decrease continuously
