Modelación, simulación y control de procesos de fermentación

Abstract

We present a simulator in Matlab/Simulink environment to control the fermentation process, designing an invariant control law, after that a stabilizing control to keep the plant within the reference system and finally a stabilizing control improved with the implementation of a fuzzy controller. The Monod model is used and tested via simulation above strategies in order to control the specific growth rate of biomass. The stabilizing control is applied above the invariant law and the fuzzy PI was improved behavior compared with traditional PI control.
