Abstract :
A MATLAB/SIMULINK-based simulator was employed for studies concerning the control of baker´s yeast fed-batch fermentation. Four control algorithms were implemented and compared: the classical PID control, two discrete versions-modified velocity and position algorithms, and a fuzzy law. The simulation package was seen to be an efficient tool for the simulation and tests of control strategies of the nonlinear process
