Abstract

When thermal energy flows between fluids, from a solid surface to a fluid, or between
particles, and the flow of that thermal energy occurs at different temperatures, that
combination of fluid and thermal energy is known as a heat exchanger. Industrial heating
and cooling heat exchangers are commonly employed. Applications in the transportation,
building, chemical, and refrigeration industries. For the heat exchanger process the suitable
control scheme is provided by implementing the cascade control with optimized PID
controller with various optimization techniques such as ZN method, Process Reaction
Curve method and Fmincon-GA optimization techniques. The optimization is included to
minimize the maximum peak overshoot to less than 5 %, the settling time 10% and nullifying
the offset.
