  1. 6. Optimized processes in sawmills

    Författare :Carl Gustav Lundahl; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Technology; Träteknik;

    Sammanfattning : This work was initiated in order to show the potential for Swedish sawmills to achieve higher productivity by implementation of improved process control tools in breakdown and production flows. Accessible and reliable production data are crucial information concerning the area of process control; hence the objective in this study was to create a "toolbox" of suitable tools for decision support, surveys and analyses.

  3. 7. Recipe-Based Batch Control Using High-Level Grafchart

    Författare :Charlotta Johnsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Batch control; Grachart;

    Sammanfattning : High-Level Grafchart is a graphical programming language for control of sequential processes. Sequential control is important in all kinds of industries: discrete, continuous and batch. Sequential elements show up both on the local control level and on the supervisory control level. LÄS MER

  5. 9. Traceability methods for continuous processes

    Författare :Björn Kvarnström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management;

    Sammanfattning : The subject of this thesis is traceability in continuous processes, i.e. the ability to trace products or batches through a certain process. Examples of the benefits from traceability are that it minimises the extent to which products are affected by product recalls and assures lot uniformity in production. LÄS MER

  7. 10. Perturbation-based Control of Industrial Fed-batch Bioprocesses

    Författare :Ola Johnsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perturbation-based control; process control; fed-batch control; industrial bioprocesses;

    Sammanfattning : The topic of this thesis is bioprocess control, more specifically control of industrial-scale microbial fed-batch bioprocesses. Its focus is therefore on methods which are easy to implement in an industrial setting, which gives certain limitations on sensors, actuators and control systems. LÄS MER
