PID control theory

[Mauricio77]

I am trying to undertand a little more about PID control theory (Proportional, Integral, Derivative) because I want to improve a Tension Control System and design it under this control theory, so, does anyone has literature regarding this topic? or a hint where I can find a deep discusion (under an engineering point of view) regarding this?

I will appreciate all your replies.

Thanks!!!!

Do an Internet search. There is a ton of information available on PID theory, tuning, etc.

Suggestion: They were dealt with thoroughly in the past before state variables became strong. Old book from 60ties or so can be very useful, e.g.:
Winfried Oppelt "Handbook of Regulation" originally German and translated to many languages.
William S. Levine "The Control Handbook," CRC Press, IEEE Press, 1996.
Etc.
