  2. 1. Thermo-electric temperature measurements in friction stir welding : Towards feedback control of temperature

    Author : Ana Magalhães; Gunnar Bolmsjö; Jeroen De Backer; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FSW; Robotic; Temperature; TWT; Plunge; Control; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Friction Stir Welding has seen a fast uptake in many industry segments. Mechanical properties superior to fusion welding, the ability to weld "unweldable" aluminium alloys and low distortion are often described as the main reasons for the fast industrial implementation of FSW. Most existing applications consist of long straight welding joints. READ MORE

  4. 2. Nonlinear Identification and Control with Solar Energy Applications

    Author : Linda Brus; Bengt Carlsson; Torbjörn Wigren; Graham C. Goodwin; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; feedforward control; model predictive control; nonlinear control; nonlinear systems; recursive identification; solar power; system identification; time delay systems; Automatic control; Reglerteknik; Reglerteknik; Automatic Control;

    Abstract : Nonlinear systems occur in industrial processes, economical systems, biotechnology and in many other areas. The thesis treats methods for system identification and control of such nonlinear systems, and applies the proposed methods to a solar heating/cooling plant. READ MORE

  5. 3. Modeling and Control of the Paper Machine Drying Section

    Author : Ola Slätteke; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; robotteknik; Automatiska system; Moisture control; Paper-making; Pressure control; Predictive Control; Mid-ranging Control; Wood; Drying Section Modeling; Automation; control engineering; robotics; pulp and paper technology; Pappers- och massateknik;

    Abstract : The topic of this thesis is modeling and control of the last part of the paper machine - the drying section. Paper is dried by letting it pass through a series of steam heated cylinders and the evaporation is thus powered by the latent heat of vaporization of the steam. READ MORE

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

    Author : Lena de Maré; Institutionen för reglerteknik; []

    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

  7. 5. Modeling, Control and Optimization of a Plate Reactor

    Author : Staffan Haugwitz; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mid-ranging control; transition control; start-up; exothermic reaction; chemical reactor; modeling; process control; optimization; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : A new chemical reactor, the Alfa Laval Plate Reactor, is being developed by Alfa Laval, a Swedish world-leading heat exchanger company. The plate reactor combines the high-heat-transfer capabilities of plate heat exchangers with the efficient mixing and reaction control typical of microreactors. READ MORE
