Design of a Robust sliding mode controller for bioreactor cultures in overflow metabolism via an interdisciplinary approach

Blog Article

Microorganism culture is highly complex due to the different metabolic pathways, which are very complex.A metabolic phenomenon called overflow is a challenge to overcome in automatic control tasks of microorganism cultures.In this study, a nonlinear algorithm by T-Shirt sliding modes (sliding mode nonlinear control, SMNC) is proposed for the robust regulation of a fed-batch bioreactor in the presence of parametric and system perturbations.

A control design is obtained using Lyapunov functions by techniques to propose a control law such that it is robust, only the output signals Top Load Washer (biomass and volume) are used, and the reaction rates do not have to be wholly known.Therefore, a novel and simple controller capable of solving the above problems is obtained.
