  2. 1. Realising full-scale control in wastewater treatment systems using in situ nutrient sensors

    Author : Pernille Ingildsen; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; robotteknik; Automatiska system; control engineering; Instrumentation; Wastewater treatment; Control; Full-scale plants; Control structures; Electronics and Electrical technology; Elektronik och elektroteknik; robotics; Automation; kontroll av utsläpp; pollution control; Miljöteknik; Environmental technology;

    Abstract : Abstract A major change in paradigm is taking place in the operation of wastewater treatment plants as automatic process control is becoming feasible. This change is due to a number of different reasons, not least the development of online nutrient sensors, which measure the key parameters in the biological nutrient removal processes, i.e. READ MORE

  4. 2. Non-intrusive instrumentation and estimation : Applications for control of an additive manufacturing process

    Author : Petter Hagqvist; Anna-Karin Christiansson; Bengt Lennartson; Stewart Williams; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; Automation; Emissivity; Emissivity Compensated Spectral Pyrometry; Laser Metal Wire Deposition; Metal Deposition; Pyrometry; Resistance Feedback Control; Thermometry; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : For integration of additive manufacturing into industrial production, there is a need for capable yet robust automation solutions. Such solutions are to ensure consistent process outputs, both with regard to deposit geometry and material properties. READ MORE

  5. 3. Instrumentation, Control and Automation in Anaerobic Digestion

    Author : Jing Liu; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; ICA; automation; control; monitoring; biosensor; instrumentation; anaerobic digestion; biogas;

    Abstract : Anaerobic digestion (AD) is a biochemical process in nature. It has been used to decompose organic waste in order to reduce environmental pollution, and to destroy pathogenic microorganisms for the protection of human and animal health. The process itself produces methane, which can then be used as an energy source. READ MORE

  6. 4. Data-Rich Multivariable Control of Heavy-Duty Engines

    Author : Maria Henningsson; Institutionen för reglerteknik; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. Cavity Field Control for High-Intensity Linear Proton Accelerators

    Author : Olof Troeng; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Particle Acceleration; Automatic Control; European Spallation Source;

    Abstract : The European Spallation Source will, once fully operational in 2025, be the world's brightest neutron source. The neutrons will be generated by bombarding a tungsten target with protons accelerated to 96\% the speed of light by electromagnetic fields confined in 155 radio-frequency cavities along the world's most powerful linear accelerator.
