  1. 1. PID control of TITO systems

    Författare :Pontus Nordfeldt; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decoupling; PID Control; Linear Systems; Process Control; Multi-variable Control;

    Sammanfattning : This thesis treats controller design and tuning for systems with two input signals and two output signals in the process industry. Two design methods that can be combined to form a core in an algorithm for automatic design and tuning for the considered systems are presented. LÄS MER

  2. 2. Glycemic Control and Temperature Control in Buildings

    Författare :Meike Stemmann; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; MEDICIN OCH HÄLSOVETENSKAP; ENGINEERING AND TECHNOLOGY; MEDICAL AND HEALTH SCIENCES; Diabetes; Prediction; Optimization; Decision Support System; Inverted Decoupling; PID; Buildings; Ventilation System;

    Sammanfattning : This thesis consists of two parts, applying concepts from automatic control to different application areas.The first part of this thesis concerns the development of an optimization-based algorithm, determining the size of insulin and glucose doses for patients suffering from Diabetes Mellitus and treated with multiple insulin injections.

  3. 3. Exception Handling in Recipe-Based Batch Control

    Författare :Rasmus Olsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; S88; grafchart; exception handling; recipe; batch;

    Sammanfattning : The focus of this thesis is exception handling in recipe-based batch control. Exception handling is a critical element for achieving long-term success in batch production. It is reported to constitute 40-60 percent of the batch control design and implementation effort. LÄS MER

  4. 4. Model-Based Optimization of Combustion-Engine Control

    Författare :Gabriel Turesson; Institutionen för reglerteknik; []
    Nyckelord :Model Predictive Control MPC ; Partially Premixed Combustion; Pressure Sensor Feedback; Model Based Control; Particle Filter; Multiple Fuel Injections; Gasoline Compression Ignition; Model Predictive Control MPC ; Partially Premixed Combustion PPC ; Low Temperature Combustion; Model Based Control; Multiple Fuel Injections; Pressure Sensor Feedback; Particle Filter; Gasoline Compression Ignition;

    Sammanfattning : The work presented in this thesis is motivated by the need to reliably operate a compression-ignition engine in a partially premixed combustion (PPC) mode. Partially premixed combustion is a low temperature combustion concept, where the ignition delay is prolonged to enhance fuel-air mixing in the combustion chamber before the start of combustion.

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

    Författare :Anneli Orvnäs; Sebastian Stichel; Rickard Persson; Roger Goodall; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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;

    Sammanfattning : 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. LÄS MER
