An Improved PID controller Design based on Model Predictive Control for a Shell and Tube Heat Exchanger

In this paper an algorithm of PID controller based on model predictive control is designed for a shell and tube heat exchanger. PID controllers and model predictive controls are two control algorithm mostly used these types of process applications. The three parameters of PID controller must be tuned to the process to obtain a satisfactory closed loop process performance. The model of the heat exchanger is identified by using principles and empirical method. The proposed PID algorithm is used for controlling a temperature of a shell and tube heat exchanger. The results of the proposed controller are compared with conventional PID and model predictive control. The result shows that the PID controller based on model predictive control gives excellent performance.
