Description

In this paper we present a simple computer-based laboratory set-up for experiments concerning real-time system identification. The set-up is constituted by a 'Process Simulator' computer and a 'Control' computer, communicating via serial RS-232 protocol. The former can simulate multivariable non-linear systems in real-time, in this specific experiment the fed-batch fermentation of baker's yeast. The latter performs the tasks of system identification and control, viz - (i) identification is performed employing a methodology based on a general non-linear deterministic model representation of fed-batch fermentations; (ii) control is performed employing an adaptive linearizing scheme.
