Application of Proportional-Integral-Derivative (PID) Regulator for Regulation of Basic Parameters in Production Process

Abstract

Proportional-Integral-Derivative (PID) control is the most common control algorithm used
in industry and has been universally accepted in industrial control. The PID controller is
composed of three distinct parts called Proportional, Integral, and Derivation, each of them
accept the error signal as internal signal and operates on it, and ultimately the final signal of
their output is combined together. The output signal of them, which is the same signal of PID
output, is sent to the system for error correction. For this reason, we need to know the
correctness of their operation by checking the regular measuring equipment. An enhanced
PID developed for wireless measurements has been found to inherently eliminate oscillations
from a wide variety of sources including discontinuous and delayed responses in the
automation system and interactions between loops when used with a threshold sensitivity
setting and the dynamic reset limit. The advancements in new techniques and a greater
understanding of existing capabilities enable the PID to not only improve loop performance
but to individually optimize unit operations. For this reason, types of controllers that are more
common in the chemical industry and which deals with the use and exploitation of operators
closed loop systems, the theory of classical PID and the effects of tuning a closed loop control
system are discussed in this paper. Finally, we find exact gain for controlling basic
parameters; at first we control the level.
