Computer-aided teaching of process engineering : VI - studies on bioprocess identification and control through a process simulator

摘要

In this paper we present a simple computer-based laboratory set-up for experiments concerningreal-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 simulatemultivariable non-linear systems in real-time, in this specific experiment the fed-batchfermentation 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-lineardeterministic model representation of fed-batch fermentations; (ii) control is performedemploying an adaptive linearizing scheme.
