Modelling for Temperature Non-Isothermal CSTR Using Fuzzy Logic

Many types of controllers have been applied on the Continuous Stirred Tank Reactor (CSTR) process to control the reactor temperature. In this book, an analysis of the response of the conventional Proportional-Integral-Derivative (PID) controller and multi types of fuzzy logic controller for temperature control of CSTR and to design a control system of a non-isothermal temperature control of a CSTR in order to produce the most theoretically stable response curve. A mathematical model of a CSTR using the most general operating condition was developed through a set of differential equations. The introduction of the most basic proportional-integral-derivative controller to the system will be shown and an activity plot or response curve can be shown to explain the behavior of the system with and without controller. The fuzzy logic controller from the fuzzy logic toolbox and compare the results that the temperature control is found better with fuzzy logic control as compared to PID control schemes respectively.
