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.engBaker’s yeast fermentationPID controlFuzzy controlconference object10.1109/IECON.2001.976712
