  2. 21. Dependable Distributed Control System : Redundancy and Concurrency defects

    Author : Bjarne Johansson; Thomas Nolte; Alessandro Papadopoulos; Luis Almeida; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Abstract : Intelligent devices, interconnectivity, and information exchange are characteristics often associated with Industry 4.0. A peer-to-peer-oriented architecture with the network as the system center succeeds the traditional controller-centric topology used in today's distributed control systems, improving information exchange in future designs.

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

    Author : Lena de Maré; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; control engineering; Automatiska system; robotteknik; reglerteknik; Automation; Temperature; Mid-ranging control; Amino acid; Complex media; Fed-batch bioreactors; Probing control; Biotechnology; Bioteknik; Parameter estimation; Feeding strategies;

    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

  5. 23. 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

  6. 24. Control of EGR and VGT for emission control and pumping work minimization in diesel engines

    Author : Johan Wahlström; Lars Nielsen; Lars Eriksson; Tore Hägglund; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mean value modeling; Oxygen fuel ratio; EGR-fraction; System analysis; Sign reversal; PID-control; European Transient Cycle; Automatic control; Reglerteknik;

    Abstract : Legislators steadily increase the demands on lowered emissions from heavy duty vehicles. To meet these demands it is necessary to integrate technologies like Exhaust Gas Recirculation (EGR) and Variable Geometry Turbochargers (VGT) together with advanced control systems. READ MORE

  7. 25. PID Control, Design, Extension, Application

    Author : Helene Panagopoulos; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; PID control. Design. Optimization. Load disturbance rejection. Measurement noise filtering. Set point response.

Pulp and paper.; robotics; Automation; Automatiska system; robotteknik; reglerteknik;

    Abstract : This thesis considers the design of PID controllers, the extensions of these controllers to improve their performance, and the applications of these design methods to industrial processes. New tuning methods for PI and PID controllers have been presented. These methods uses a model of the process to be controlled, given as a transfer function. READ MORE
