  1. 26. On repetitive control

    Författare :Gunnar Hillerström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : This thesis will concern control systems ability to enhance performance by repeating, while maintaining a stable and sufficiently fast closed loop performance. Iterative techniques can be divided into repetitive and learning control. LÄS MER

  2. 27. Probing Control of Glucose Feeding in Escherichia coli Cultivations

    Författare :Mats Åkesson; Institutionen för reglerteknik; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 28. Integer Quadratic Programming for Control and Communication

    Författare :Daniel Axehill; Anders Hansson; Manfred Morari; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integer Quadratic Programming; Model Predictive Control; Hybrid Systems; Semidefinite Programming; Code Division Multiple Access; Multiuser Detection; Automatic Control; Communication; Automatic control; Reglerteknik;

    Sammanfattning : The main topic of this thesis is integer quadratic programming with applications to problems arising in the areas of automatic control and communication. One of the most widespread modern control methods is Model Predictive Control (MPC). In each sampling time, MPC requires the solution of a Quadratic Programming (QP) problem. LÄS MER

  4. 29. Management Control : Linking Strategy with Inter‐Organisational Relationships

    Författare :Zita Ambrutytė; Jonas Gerdin; Linköpings universitet; []
    Nyckelord :Management control systems; business strategy; inter-organisational relationships; management control variables; intra-organisational controls; Management control systems; styrsystem; affärsstrategi; inter-organisatoriska relationer; styrvariabler; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : The alignment of strategies and control systems is believed to affect the chances for firms to successfully achieve competitive edge. Contemporary business trends like globalization, vertical disintegration, the reduction in supplier bases, the focusing of operations and outsourcing of non-core activities, have caused companies to rely increasingly on relationships with other firms.

  5. 30. Data-Rich Multivariable Control of Heavy-Duty Engines

    Författare :Maria Henningsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multivariable Control; Model Predictive Control; LQG Control; Virtual Sensing; System Identification; Diesel engines; HCCI engines; Dual-Fuel Combustion; Cylinder Pressure Sensors;

    Sammanfattning : The combustion engine is today the dominant technology for transportation of goods and people world-wide. Concerns for global warming, toxic exhaust emissions, as well as cost and availability of fuel have in recent years created incentives for technological evolution of combustion engines. LÄS MER
