4. 2. Closed-Loop Control of HCCI Engine Dynamics

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

   Abstract : The topic of the thesis is control of Homogeneous Charge Compression Ignition (HCCI) engine dynamics. HCCI offers a potential to combine high efficiency with very low emissions. In order to fulfill the potential benefits, closed-loop control is needed. READ MORE

5. 3. On Sensor-Controlled Robotized One-off Manufacturing

   Author : Per Cederberg; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; one-off manufacturing; arc welding; world model; real-time; task-oriented programming; simulation; control; robotics; sensor; Automation; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : A semi-automatic task oriented system structure has been developed and tested on an arc welding application. In normal industrial robot programming, the path is created and the process is based upon the decided path. Here a process-oriented method is proposed instead. READ MORE

6. 4. Integrated Control and Real-Time Scheduling

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

   Abstract : The topic of the thesis is codesign of flexible real-time control systems. Integrating control theory and real-time scheduling theory, it is possible to achieve higher resource utilization and better control performance. The integration requires new tools for analysis, design, and implementation. READ MORE

7. 5. 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
