SURESH BABUAbstract In this paper an algorithm is developed based on model predictive control for controlling the temperature of a shell and tube heat exchanger. Model predictive and PID controllers are two control algorithm mostly used for controlling the temperature of the heat exchanger. The control parameters of PID controller should be tuned to the process to obtain a satisfactory closed loop process performance and also conserve the energy. The model of the heat exchanger is designed using principles and empirical method. The proposed algorithm is used for controlling a temperature of a shell and tube heat exchanger. The result of proposed controller is compared with conventional PID and model predictive controller. The result shows that PID controller based on dynamic matrix control gives excellent performance.
