1. 1. Look-ahead Control of Heavy Vehicles

   Författare :Erik Hellström; Lars Nielsen; Jan Åslund; Lino Guzzella; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automotive control; dynamic programming; predictive control; fuel-optimal control; long haulage truck; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Automatic control; Reglerteknik;

   Sammanfattning : Trucks are responsible for the major part of inland freight and so, they are a backbone of the modern economy but they are also a large consumer of energy. In this context, a dominating vehicle is a truck with heavy load on a long trip. LÄS MER

3. 2. Control of Systems with Limited Capacity

   Författare :Stefan Solyom; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; voltage collapse; power systems; anti-windup; piecewise linear systems; synthesis; ABS; PID control; LMI; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Sammanfattning : Virtually all real life systems are such that they present some kind of limitation on one or many of its variables, physical quantities. These systems are designated in this thesis as systems with limited capacity. This work is treating control related problems of a subclass of such systems, where the limitation is a critical factor.

4. 3. Probing Control : Analysis and Design with Application to Fed-Batch Bioreactors

   Författare :Stéphane Velut; Institutionen för reglerteknik; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

5. 4. Performance Quantification of Interarea Oscillation Damping Using HVDC

   Författare :Joakim Björk; Karl H. Johansson; Lennart Harnefors; Robin Preece; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVDC transmission control; interarea oscillations; power oscillation damping; small-signal stability; frequency control; controllability; MIMO control; decoupling control; multivariable interaction; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : With the transition towards renewable energy, and the deregulation of the electricity market, generation patterns and grid topology are changing. These changes increase the need for transfer capacity. One limiting factor, which sometimes leads to underutilization of the transmission grid, is interarea oscillations. LÄS MER

7. 5. Modeling and Control of the Open Plate Reactor

   Författare :Staffan Haugwitz; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process control; process intensification; heat exchange reactor; mid-ranging control; extended Kalman filter; model predictive control;

   Sammanfattning : The focus of this thesis is on modeling and control of the Open Plate Reactor (OPR), a new heat exchange reactor being developed by Alfa Laval AB. It combines intensified mixing with enhanced heat transfer capacity into one operation. LÄS MER
