Fuzzy Logic Control Strategy and Instrumentation of Shell and Tube Heat Exchangers

The main control issue in a heat exchanger system is to regulate the outlet cold fluid temperature according to the setpoint. An appropriate control system is required in handling the heat exchange, whereby it involves the setpoint achievement of the system resulting in an excellent performance of the temperature control. In this paper, a comprehensive study regarding the standard PID controller and intelligent control such as Fuzzy logic control (FLC), FPID controller has been made. This study aims to develop a control system and to find the most effective optimization technique for the temperature control system of STHE. The comparison between controllers’ performance based upon the transient response concerning the time domain specification has been carried out. As the findings from the data analysis, the FPID controller is one of the effective control techniques in controlling the outlet temperature of cold water in STHE as an improvement to the PID controller. From the transient response functionality, it is proven that the combination of FLC and PID controller delivered a good output response with minimal overshoot, rise time, and settling time.
