  4. 2. On Active Secondary Suspension in Rail Vehicles to Improve Ride Comfort

    Author : Anneli Orvnäs; Sebastian Stichel; Rickard Persson; Roger Goodall; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rail vehicle; active secondary suspension; ride comfort; sky-hook damping; H∞ control; multi-body simulations; on-track tests; Järnvägsgruppen - Gröna tåget; Järnvägsgruppen - Gröna tåget; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik;

    Abstract : One way to make rail vehicles a competitive means of transportation is to increase running speed. However, higher speeds usually generate increased forces and accelerations on the vehicle, which have a negative effect on ride comfort. With conventional passive suspension, it may be difficult to maintain acceptable passenger comfort. READ MORE

  6. 4. 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

  7. 5. Control of DC voltage in Multi-Terminal HVDC Transmission (MTDC) Systems

    Author : Mohammad Nazari; Mehrdad Ghandhari; Nicklas Johansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : With recent advances in power electronic technology, High-Voltage Direct Current (HVDC) transmission system has become an alternative for transmitting power especially over long distances. Multi-Terminal HVDC (MTDC) systems are proposed as HVDC systems with more than two terminals. These systems can be geographically wide. READ MORE
