HI, I have been reading all the pid related posts on this site and had an Idea what it is, but still have a question..now why do I have to set for example 30 minuts for the integral ("I")?? What will happen in 30 minutes of time ??
I understand how proportional works...it scale the input signal eg. from an analog input(this is the PV), then compare it with the setpoint
this is the SP, and act accordingly, here I am a little confused..why do I need the integral term ??
any help that will enlighten me I will appriciate alot.
ps: I'd read all the post related to pid so please don't suggest to use the search button on the top of this page loooooooool
thanks in advance
