Abstract
Regulation of the biomass specific growth rate is an important goal in many fermentation fed-batch processes. Inspired in an invariant control law, we propose in this paper a controller with the structure of a partial state feedback with gain dependent on the output error. Further, to make the desired state trajectory effectively invariant despite modeling errors and parameter variations, the feedback gain is continuously adapted by means of a sliding mode algorithm. The stability properties of the closed–loop process are investigated in detail.
