Mathematical Modelling and Variable Structure Control Systems for Fed-Batch Fermentation of Escherichia coli

In this paper some problems of the mathematical modelling and high control algorithms of feed-batch fermentation process of Escherichia coli are considered. An unstructured mathematical model for E. coli feed-batch fermentation is developed on the base of FIA measurements. Methodology for the models’ parameters estimation is proposed on the basis of nonlinear optimization methods. The model acc...

Modelling and Control of Process Industry Batch Production Systems

Many models of process industry batch production systems are of a continuoustime/discrete-event (CT/DE) nature: physical processes are modelled using CT specifications, operating procedures are modelled using DE specifications. For scheduling of batch production systems, special purpose tools are available. The Chi language is a CT/DE language with high level DE language elements. This makes it...

Modelling A PCT40 Heat Exchanger For Control Purposes

This paper presents a simulation model of a PCT40 heat exchanger. It starts with a motivation, followed by description of the system and of the whole modelling process. The mathematical model includes simplified description of heating and cooling systems together with a more detailed description of a proportioning solenoid valve. It is formed using combination of both analytical and empirical a...

An IMC-DMC Control for Heat Exchanger Process

In this paper, a novel method to eliminate the steady-state offset that is encountered when dealing with load change occurs in processes is proposed for identified heat exchanger process model. The algorithm proposed is based on the fact that DMC algorithm is equivalent to an IMC structure. Then we can improve conventional DMC using a modified IMC structure to remove the offset. A simulation re...
