2. 1. Probing Control : Analysis and Design with Application to Fed-Batch Bioreactors

   Author : Stéphane Velut; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronik och elektroteknik; Electronics and Electrical technology; Large scale fermentations; Extremum control; Feeding strategy; Probing control; Fed-batch bioreactors; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : In most control problems the objective is to control the output at a desired value in spite of disturbances. In some cases, the best setpoint is not known a priori and it should be found online to optimize the process performance. This thesis examines a probing strategy that can be applied for this class of problems. READ MORE

4. 2. Feeding Strategies Based on Probing Control for E. coli and V. cholerae Cultivations

   Author : Lena de Maré; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; control engineering; Automatiska system; robotteknik; reglerteknik; Automation; Temperature; Mid-ranging control; Amino acid; Complex media; Fed-batch bioreactors; Probing control; Biotechnology; Bioteknik; Parameter estimation; Feeding strategies;

   Abstract : The recombinant DNA techniques have made it possible to produce many different proteins for a wide range of applications. The vector encoding for the recombinant protein is often inserted in the bacterium E. coli as it is a well studied and a well-known organism. To achieve a high productivity, it is important to reach a high cell density. READ MORE

5. 3. Probing Control of Glucose Feeding in Escherichia coli Cultivations

   Author : Mats Åkesson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatiska system; control engineering; robotics; Automation; dissolved oxygen; acetate; glucose feeding; robotteknik; Escherichia coli; Process control; fed-batch cultivation; reglerteknik; Biotechnology; Bioteknik;

   Abstract : Production of many proteins can today be made using genetically modified organisms. One of the most frequently used host organisms is the bacterium Escherichia coli. A difficulty encountered in cultivations of E. coli is the accumulation of the metabolic by-product acetate which inhibits cell growth and production of a desired protein. READ MORE

6. 4. On Robot Control using Range Sensors : with Special Reference to Active Uncertainty Reduction

   Author : Bernt Nilsson; Aarne Halme; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Robot Gripping and Docking; Gripper-Object Feedback; Non-contact Sensing; Laser Ranging; Flexible Arm; Mobile Robot; Probing; Dual Control; LQG-Feedback;

   Abstract : This thesis addresses the problem of positioning robots relative to objects in the surrounding work space. The object's position and orientation (posture) are measured using a non-contact sensor on-board the robot. For gripping/docking tasks the goal posture is specified relative to the object and not in a fixed coordinate system of the robot. READ MORE

7. 5. Topics in Modeling, Control, and Implementation in Automotive Systems

   Author : Magnus Gäfvert; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; Automation; robotics; robotteknik; Automatiska system; control engineering;

   Abstract : This thesis treats different aspects of automotive control-systems and consists of four papers covering different areas in this large field. The first paper presents a 9-degrees-of-freedom dynamic model of a tractor-semitrailer vehicle, aimed at simulation and evaluation of active chassis-systems for stability enhancements. READ MORE
