Modelling and Control of Biotechnical Processes


Book Description

Modeling and Control of Biotechnical Processes covers the proceedings of the First International Federation of Automatic Control Workshop by the same title, held in Helsinki, Finland on August 17-19, 1982. This book is organized into seven sections encompassing 37 chapters. The opening section deals with the measurement techniques in fermentation processes and the use of automated analyzers to control microbial processes. The next sections consider the concepts of bioreactor modeling and related problems, as well as the modeling and control of biological wastewater treatment processes. Other sections discuss the economic and static optimization, the computer control of production processes, and the application of estimation and identification methods to biotechnological processes. The final sections explore the principles of real-time analysis, use of computer control in specific biotechnical production, process control design, and the modeling of adaptive control. This book is of great value to biotechnologists, biochemists, and control engineers.




Modelling and Control of Biotechnological Processes


Book Description

Modelling and Control of Biotechnological Processes contains the proceedings of the International Federation of Automatic Control's First Symposium on Modeling and Control of Biotechnological Processes held in Noordwijkerhout, The Netherlands, on December 11-13, 1985. The papers explore modeling and control of biotechnological processes such as fermentation and biological wastewater treatment. This book consists of 37 chapters divided into 11 sections and begins with a discussion on the control of fermentation processes; modeling of biotechnical processes; and application of measurement and estimation techniques to biotechnology. The following sections focus on adaptive control theory, applications of adaptive control, and control and modeling of bioreactors. The reader is also introduced to measurement techniques and sensors, with emphasis on pyrolysis mass spectrometry; rapid bioelectrochemical methods; and a self-tuning controller for multiloop controlled fed-batch fermentation. The remaining sections deal with parameter identification and estimation; Kalman filtering techniques; optimization of production processes; modeling of microkinetics; and optimization theory. This monograph will be of interest to researchers and practitioners in the field of biotechnology.




Computer Applications in Fermentation Technology: Modelling and Control of Biotechnological Processes


Book Description

Richard Fox Chairman, Scientific Programme Committee Between 25th and 29th September, 1988, 243 people who either apply or research the use of computers in fermentation gathered together at Robinson College, Cambridge, UK. They came from 30 countries. The conference brought together two traditions. Firstly, it continued the series on Computer Applications in Fermentation Technology (ICCAFT) inaugurated by Henri Blanchere in Dijon in 1973 and carried forward in Philadelphia and Manchester. Secondly, it brought the expertise of the many members of the International Federation of Automatic Control (IFAC), who focused their attention on biotechnology at Noordwijkerhout in the Netherlands in December, 1985. I am happy to say that the tradition carries on and a successor meeting will hopefully take place in the USA in 1991. If you find these proceedings useful or stimulating, then we hope to see you there. We set out to make ICCAFT4 a close-knit friendly conference. We housed all who cared to in Robinson College itself and organised no parallel sessions. Because we, the organisers, experience difficulty with the jargon of our colleagues from other disciplines, we asked Bruce Beck to present a breakfast tutorial on modern control and modelling techniques, and we set up informal panel discussions after dinner on two evenings. Neville Fish chaired a forum on the microbiological principles behind models, while Professors Derek Linkens and Ron Leigh led a discussion on expert systems in control.







Modelling and Optimization of Biotechnological Processes


Book Description

Mostindustrialbiotechnologicalprocessesareoperatedempirically.Oneofthe major di?culties of applying advanced control theories is the highly nonlinear nature of the processes. This book examines approaches based on arti?cial intelligencemethods,inparticular,geneticalgorithmsandneuralnetworks,for monitoring, modelling and optimization of fed-batch fermentation processes. The main aim of a process control is to maximize the ?nal product with minimum development and production costs. This book is interdisciplinary in nature, combining topics from biotechn- ogy, arti?cial intelligence, system identi?cation, process monitoring, process modelling and optimal control. Both simulation and experimental validation are performed in this study to demonstrate the suitability and feasibility of proposed methodologies. An online biomass sensor is constructed using a - current neural network for predicting the biomass concentration online with only three measurements (dissolved oxygen, volume and feed rate). Results show that the proposed sensor is comparable or even superior to other sensors proposed in the literature that use more than three measurements. Biote- nological processes are modelled by cascading two recurrent neural networks. It is found that neural models are able to describe the processes with high accuracy. Optimization of the ?nal product is achieved using modi?ed genetic algorithms to determine optimal feed rate pro?les. Experimental results of the corresponding production yields demonstrate that genetic algorithms are powerful tools for optimization of highly nonlinear systems. Moreover, a c- bination of recurrentneural networks and genetic algorithms provides a useful and cost-e?ective methodology for optimizing biotechnological processes.




Bioreaction Engineering


Book Description

Alongside presenting the fundamentals, this book reviews the state of the art of mathematical modeling and control of bioprocesses, while demonstrating the application in various biological systems important to industry. At the same time, the application of different types of models and control strategies are illustrated, taking into account the recent developments in reactor modeling. In addition to modeling and control, the metabolic flux analysis and the metabolic design and their application to bioprocesses are considered.

Model Based Process Control


Book Description

Presented at this workshop were mathematical models upon which process control is based and the practical applications of this method of control within industry; case studies include examples from the paper and pulp industry, materials industry and the chemical industry, among others. From these presentations emerged a need for further research and development into process control. Containing 19 papers these Proceedings will be a valuable reference work for all those involved in the designing of continuous production processes for industry and for the end user involved in the practical application of process control within their manufacturing process.




Methods of Model Based Process Control


Book Description

Model based control has emerged as an important way to improve plant efficiency in the process industries, while meeting processing and operating policy constraints.

Dynamic Modelling and Control of National Economies 1989


Book Description

The Symposium aimed at analysing and solving the various problems of representation and analysis of decision making in economic systems starting from the level of the individual firm and ending up with the complexities of international policy coordination. The papers are grouped into subject areas such as game theory, control methods, international policy coordination and the applications of artificial intelligence and experts systems as a framework in economic modelling and control. The Symposium therefore provides a wide range of important information for those involved or interested in the planning of company and national economics.
