These controllers have proven to be robust and extremely beneficial in the control of many important applications.
PID stands for: P (Proportional)
I (Integral)
D (Derivative) کنترلر PID 18 Historical Note Early feedback control devices implicitly or explicitly used the ideas of proportional, integral and derivative action in their structures.
However, it was probably not until Minorsky’s work on ship steering* published in 1922, that rigorous theoretical consideration was given to PID control.
This was the first mathematical treatment of the type of controller that is now used to control almost all industrial processes. (more that 95% of closed-loop industrial processes.)
