Abstract: “A program in MATLAB’s Graphical User Interface (GUI) is developed to study dynamic behavior and traditional PID control of simple nonlinear reference systems, such as a discontinuous batch reactor and a continuous bioreactor. Once either system is selected by the GUI user, the program underlying the GUI provides simulation for various values of the input variables in an easy and intuitive way, showing a strong educational value. It allows exploration of simulation, modeling and control for users without theoretical knowledge.”
