An analysis on modeling and optimal control of the heat exchangers using PI and PID controllers

In this paper the dynamic behaviour of the heat exchangers are studied using different control strategies. By experimentation the dynamic behaviour of the outlet cold water temperature for the change in hot water flow rate are observed and the values are simulated using MATLAB and the results are compared. The conventional PI and PID are implemented and the control strategies along with the tuning procedures such as ISE, IAE, ITAE are observed and the design fitness of the heat exchangers are analyzed for effective control of the process there by improving the performance and the heat transfer rate of the heat exchanger irrespective of sudden disturbance or nonlinearity of the process.
