  2. 21. 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. 22. Dryer Section Control in Paper Machines During Web Breaks

    Author : Jenny Ekvall; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dryer Section; Web breaks; Paper machine; steam pressure control; Physical modeling; Automatic control; Reglerteknik; Dryer section; paper machine; physical modeling; steam pressure control; web breaks;

    Abstract : Web breaks in the dryer section of a paper machine cause loss of production and quality problems. After a web break, the steam pressure in the cylinders must be reduced to avoid overheating. READ MORE

  5. 23. Gear engagement control for transmissions in hybrid electric vehicles

    Author : Muddassar Piracha; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Noise and wear minimization; Dog Clutch; Hybrid Powertrain; Optimal control; LQI control; Mechanical Synchronizers; Dedicated Hybrid Transmission; Gear shifting; Drivability; Dual Clutch Transmission; Electric Powertrain; Phase plane analysis;

    Abstract : Hybrid and electric vehicles have become very important for vehicle manufacturers due to stricter legislation, government incentives and customers’ growing awareness of the environmental issues. For conventional vehicles, Dual clutch transmissions (DCT) have better shift quality and efficiency than conventional automatic transmissions. READ MORE

  6. 24. Identification, Diagnosis, and Control of a Flexible Robot Arm

    Author : Måns Östring; Svante Gunnarsson; Mikael Norrlöf; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Identification; Robot; Flexible; Diagnosis; Control; LQG; Recursive;

    Abstract : The most important factors in manufacturing are quality, cost, and productivity. The trend is towards lighter robots with increased mechanical flexibilities, and therefore there is a need to include the flexibilities in the robot models to obtain good performance of the robot.
