چکیده

Optimal productivity of S. cerevisiae cultures can be achieved through the regulation of the ethanol concentration at a low value. In this study, a robust control strategy is developed, which requires very little knowledge about the process, i.e. only one yield coefficient and the on-line measurement of the ethanol concentration. A Youla parametrization is selected in order to reject asymptotically the exponential growth disturbance and to robustify the control scheme against unstructured uncertainties and measurement noise. The performance of the control scheme is illustrated with real on-line experimental data. Copyright 2005 IFAC.

Optimization of A Fed-Batch Fermenter Producing Baker’s Yeast Using Simulated Annealing Method

Modeling of fermentation processes is so complicated and uncertain; therefore it is necessary to provide a robust and appropriate dynamic optimization method. In order to obtain the maximum amount of yeast (Saccharomyces cerevisiae), the bioreactor must be operated under optimal conditions. To determine substrate feeding in a fed-batch bioreactor, a simulated annealing (SA) approach was examine...

Youla Parametrization Applied to a Gpc Controlled Siso System

This paper presents a new approach based on Youla parametrization, to retune Generalised Predictive Control (GPC) law while preserving its two degrees of freedom structure. This results in a more robust controller with improved high frequency disturbance rejection properties. The proposed strategy expresses an initial controller in a powerful form via the Youla theory, each transfer function of...

Robust Controller Design for Teleoperation Systems

The controller design for a bilateral teleoperation system involves trade-offs between performance and robust stability. Beyond simple intuition, little is known how performance and robust stability trade off. This paper shows that it is possible to achieve robust stability and nominal performance of a bilateral teleoperation system by using a four-channel control architecture [1, 2]. The contr...

Kinetics of Biphasic Growth of Yeast in Continuous and Fed-Batch Cultures

The influence of dilution rate on the production of biomass, ethanol, and invertase in an aerobic culture of Succharornyces carlsbergensis was studied in a glucoselimited chemostat culture. A kinetic model was developed to analyze the biphasic growth of yeast on both the glucose remaining and the ethanol produced in the culture. The model assumes a double effect where glucose regulates the flux...

A user-friendly, low-cost turbidostat with versatile growth rate estimation based on an extended Kalman filter

For various experimental applications, microbial cultures at defined, constant densities are highly advantageous over simple batch cultures. Due to high costs, however, devices for continuous culture at freely defined densities still experience limited use. We have developed a small-scale turbidostat for research purposes, which is manufactured from inexpensive components and 3D printed parts. ...
