CONTROL STRATEGIES OF HEAT EXCHANGER

This work consists of experimental work for heat exchanger. The approach are made for comparison purpose instead of validation of experimental data. Behaviors of heat exchanger are to be observed through these approaches under two different control systems, open loop and closed loop response. The one concern is the closed loop control system, at which the behaviors are study and clarify. However, for closed loop control system to be es tablished, some data such as PI, and PID values must be calculated from the open loop control system. Then, behaviors are justified through some calculations using establ ished tuning method available in literature such as IMC based PI controller and using Ziegler - Nichols formula based PID controller.
