Heat exchanger is a device that uses to thermal energy (enthalpy) between two or more fluids, between a solid surface and a fluid, or between solid particulates and fluid, at different temperatures and in thermal contact. A variety of heat exchanger are used in industry and it classified according to transfer process, number of fluids, degree of surface compactness, construction features, flow arrangements, and heat exchanger mechanisms. One example of the application that used heat exchanger is a pilot plant, which provides design and operating information before construction of a large chemical plant. This heat exchanger usually will be controlled by PID controller. PID controller also known as conventional controller and can achieve good control performance with the proper choice of tuning parameters. However, the control performance can perform poorly and even become unstable, if improper values of the controller parameters are used. The main objective of this project is to design and simulate an advanced control strategy of heat exchanger pilot plant by using Fuzzy Logic Controller (FLC). The development of the plant model will be based on a pilot plant at Universiti Teknologi PETRONAS (UTP). While the development of the controller and all simulation work will be based on MA TLAB simulation. The aim is to improve the controller performance of pilot plant to become more smoothly, efficient, and optimize the product yield. The expected result for this project is to get the smooth process operation when using FLC compared to conventional method (PID controller). iv
