An Evaluation on Optimal Control of Shell and Tube Heat Exchanger for Various Time Delay and Disturbance

Heat exchangers in common are used to transfer heat from one medium to another. In real time systems there are much complexities that contributes to disturbance and delay in the system which often lead the process to instability because it's difficult to prevail over the effects [1]–[3]. In this paper relative analysis is done to control the output temperature of the heat exchanger system. Since it'sobligatoryto evade undesirable process variables including various time-delay theconvectional, model based and predictive controllers are studied and based on theirresult the conclusions are made. In addition to that Hybrid controller (i.e.) PID based IMC controller was studied shows for better competent temperature control over other controller for various delay and disturbance[4].
