Temperature control of Shell and Tube Heat Exchanger by using Intelligent Controllers

Abstract

Temperature control of the shell and tube heat exchanger is characteristics of nonlinear, time varying and time lag. Since the temperature control with conventional PID controller cannot meet a wide range of precision te mperature control requirement, the temperature control system of the shell and tube heat exchanger by combin ing fu zzy and PID control methods was designed in this paper. The simulation and experiments are carried out; making a comparison with conventional PID control showing that fuzzy PID strategy can efficiently improve the performance of the shell and tube heat exchanger.
