Vibrational Control Of A Class Of Bioprocesses

Abstract

The classical control techniques for bioreactors necessitate measurements of states and/or disturbances. The bioprocesses are systems that require costly and difficult on-line implementation for sensors. Vibrational control is an open-loop technique that does not requires measurements of states or disturbances. The vibrational control is applied by means of zero mean parametric vibrations for shaping the response of a linear or nonlinear system. This work addresses the problem of vibrational control for bioprocesses that take place in Continuous Stirred Tank Bioreactors (CSTB). The application of the vibrational control for two cases is discussed: the CSTB without and with recycle stream. The performances of the controlled bioprocesses are illustrated by computer simulation.
