Comparison Study of IMC and IMC Based PID Controller for Heat Exchanger System

Abstract

Heat exchanger is generally used in chemical and process industries for efficient
heating purpose of liquid steam where huge amount of heats are required and electrical
heating is not economical. This communication provides the comparative performance
analysis of different control structures such as feedback only, feedback-feed forward, Internal
Model Control, Model Predictive Control and IMC based PID control of process. In this
paper, I have studied mainly the Comparative response analysis for the heat exchanger
system using internal model control and internal model based PID control. I have got a good
set point tracking and more disturbance rejection taking place using IMC based PID control
strategy for heat exchanger system when compare to generalized internal model control.
