Abstract

A heat exchanger is a piece of equipment that continually transfers heat from one medium to another in order to carry process energy. In order to ensure its smooth operation, modeling and simulation of the system can be made so that its performance can be analyzed and improved. The scope of this study is more on simulation and software implementation of the control system design by using MATLAB. The main issue tackle in this study is to improve the performance of the heat exchanger process control. In this study, the heat exchanger is modeled using an empirical model to simulate the heat exchanger temperature response. A controller is then designed for the process using two approaches, one using a conventional PI method and another based on a fuzzy logic controller employing Mamdani inference method as an alternative approach. From the results obtained, it has been proven that both controllers are proven stable with good output temperature response. The responses of both controllers are further scrutinized where the fuzzy logic controller is shown to have better control performance compared to the PI controller. As a conclusion, intelligent control is better than the conventional PID control.
