In this work, we discuss about the process parameter identification and control of a Counter Flow Shell and Tube Heat Exchanger using Recursive Least Square Algorithm(RLS) and Self Turning controller respectively. Here, we model the process with the help of experimental data using RLS Algorithm. Then an ST controller which comes under adaptive controller is used to control the process. With the help of STC, the tube outlet temperature is controlled by adjusting the flow of cold fluid through the shell side. In conventional way a PID controller is also tuned, and the performance is compared with STC using MATLAB simulations.
