This paper presents control of the nonlinear system represented by a Continuous Stirred Tank Reactor (CSTR) using MATLAB’s Graphical User Interface (GUI). This simulation provides computation for various values of the input variables, which made this program universal for the wide range of the users without theoretical knowledge about modeling, simulation, and control.

Chemical reactors are the most influential and therefore important units that a chemical engineer will encounter. To ensure the successful operation of a Continuous Stirred Tank Reactor (CSTR) it is necessary to understand their dynamic characteristics. A good understanding will ultimately enable effective control systems design. The aim of this paper is to introduce some basic concepts of chem...
