2. 21. 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. 22. Relay Feedback and Multivariable Control

   Author : Karl Henrik Johansson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Frequency methods; Process control; Sequential control; Automatic tuning; Control education; Laboratory process; Performance limitations; Decentralized control; Multivariable zero; Multivariable systems; Hybrid control; Nonlinear dynamics; Limit cycles; Oscillations; Relay feedback; Sliding modes; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : This doctoral thesis treats three issues in control engineering related to relay feedback and multivariable control systems. Linear systems with relay feedback is the first topic. Such systems are shown to exhibit several interesting behaviors. READ MORE

5. 23. 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

6. 24. Flexible Embedded Control Systems : Design and Implementation

   Author : Johan Eker; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automation; Feedback scheduling; Quality of service; Linear quadratic control; Toolbox; Simulation; Rapid prototyping; Programming language; Scheduling; Embedded systems; Real-time system; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : Embedded control system design is a complex and error prone task, and there is a great need for better development tools. Today most real-time control systems are static systems, designed in an ad-hoc fashion. A more interactive way of working would give shorter development times, reduced costs for testing, and safer, more robust systems. READ MORE

7. 25. Methods for Control of Liquid Slosh

   Author : Mattias Grundelius; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; robotics; Automation; Electronics and Electrical technology; Elektronik och elektroteknik; Automatiska system; robotteknik; reglerteknik; Production technology; Produktionsteknik;

   Abstract : Horizontal movement of liquid containers is a common operation in an industrial packaging machine. During the movement the acceleration of the container induces motion of the liquid within the container, this is referred to as liquid slosh or liquid vibration. READ MORE
