Good Night, I’m a student of Computer Engineering here in Brazil and I’m taking this class, given that I’m trying to learn different things to complement my knowledge. Is there any way to find a transfer function or estimate other ways to find PID values based on data ( by hand or Matlab) ? Where can I find papers about estimating based on data ?

Thank you so much !

Who is proposed this approximation method?. .can you give me the reference paper!

Sir please tell me the reference book you used for this topic because I didn't find this is coughnowr or stephanopolos.
Thanks

hey thanks for your explanation. i dont get what the K is. you said that K is the steady state gain of the system, and it is equal to the change in the output divided by the change in the input. i dont understand what is the meaning of "the change in the input". i mean how did you get 1.2gpm on your data? thanks

to find K why is it (initial-final) output/(final-initial) input?

Sir please tell me the book name of that topic.. This topic I didn't get anywhere 🙏
