  2. 11. Multivariable control of a pneumatic conveying system

    Author : Wolfgang Birk; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Abstract : This licentiate thesis deals with a multivariable controller of a pneumatic conveying system. The industrial process used to illustrate design, analysis and implementation of a multivariable controller is the injection of fine coal into a blast furnace. READ MORE

  4. 12. Cavity Field Control for High-Intensity Linear Proton Accelerators

    Author : Olof Troeng; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Particle Acceleration; Automatic Control; European Spallation Source;

    Abstract : The European Spallation Source will, once fully operational in 2025, be the world's brightest neutron source. The neutrons will be generated by bombarding a tungsten target with protons accelerated to 96\% the speed of light by electromagnetic fields confined in 155 radio-frequency cavities along the world's most powerful linear accelerator.

  5. 13. Model-based control and monitoring of the flotation process

    Author : Benny Stenlund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Abstract : In the mineral processing industry, flotation constitutes the most important technique for extraction of the valuable minerals from the ore. This process involves both chemical and physical parts, the theory of which are not yet completely understood. READ MORE

  6. 14. Dead-Time Compensation and Performance Monitoring in Process Control

    Author : Ari Ingimundarson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotteknik; Automatiska system; reglerteknik; Automation; robotics; control engineering;

    Abstract : The thesis contains two parts, dead-time compensation and performance monitoring. The first part on dead-time compensation is about robust tuning procedures for dead-time compensating controllers (DTC). Both stable and integrating processes are considered. READ MORE

  7. 15. Optimization of Low-Level Controllers and High-Level Polymer Grade Changes

    Author : Per-Ola Larsson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process control; PID control; robustness; noise sensitivity; dynamic optimization; polymerization; Modelica;

    Abstract : Two design problems at different levels in the control hierarchy are considered; optimization of robust low-level controllers with constrained control signal activity and optimization of economical high-level polyethylene grade changes. As for the first design problem, a constraint on control signal activity due to measurement noise is presented and used when optimizing and comparing PI/PID controllers with measurement filters of different orders.
