  1. 1. Modeling and control of mill discharge pumps in the Aitik copper mine

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Tomas Vikner; [2018]
    Nyckelord :;

    Sammanfattning : Boliden Aitik is the largest open-pit copper mine in Sweden, and during 2017, more than 39 million tonnes of ore was processed into concentrated copper, silver and gold. The distributed control system 800xA is provided by ABB, and this is what the operators use for process monitoring and control. LÄS MER

  3. 2. Iterative Learning Control for Milling with Industrial Robots in Advanced Manufacturing

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Thomas Daun; [2014]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The demand of today for advanced manufactured parts with high precision is due to the increasing complexity of technologies. The parts are typically made by CNC (Computer Numerical Control) machines, which are expensive and comparably big. LÄS MER

  5. 4. Model Predictive Control of Skeboå Water system

    Uppsats för yrkesexamina på avancerad nivå, KTH/Reglerteknik

    Författare :Fredrik Gabrielsson; [2012]
    Nyckelord :;

    Sammanfattning : This thesis is a study of model predictive control of water levels and flows in a water system. The water system studied includes five lakes and six dams that are regulated manually by sluice-gates. The water is used in the papermaking process at Holmen Paper Mill in Hallstavik. LÄS MER

  7. 5. Reglering av transportband

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Carl Raskowski; [2012]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis investigates the possibility of improving level control in a buffer silo fed by a long conveyor belt at Stora Enso's industrial paper mill in Hyltebruk. The controller controlling the process has difficulties when the input to the conveyor belt stops since it takes at least 2.5 minutes for the empty belt segment to reach the buffer. LÄS MER
