Heat exchanger´s shell and tube modeling for intelligent control design

The shell and tube of heat exchanger is a medium where heat transfer process occurred. The accuracy of the heat exchanger depends on the performance of both elements. Therefore, both components need to be controlled in order to achieve a substantial result in the process. For this purpose, the actual dynamics of both shell and tube of the heat exchanger is crucial. This paper discusses two methods used in deriving the mathematical modeling of the system. First, physical dynamic modeling is obtained using physics and dynamics laws where actual parameters of the shell and tube are considered. Secondly, the model is determined by applying non-parametric system identification based on experimental response on the heat exchanger. Two models are used to design the shell and tube intelligent control. The intelligent control type is a Fuzzy Proportional Derivative (FPD) control. The experiment results shows that the shell and tube heat exchanger model develop using its physical parameters and controlled with FPD controller give better response, it means it can used as a model and controller of the shell and tube heat exchanger.
