1. 6. On repetitive control

   Författare :Gunnar Hillerström; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Sammanfattning : This thesis will concern control systems ability to enhance performance by repeating, while maintaining a stable and sufficiently fast closed loop performance. Iterative techniques can be divided into repetitive and learning control. LÄS MER

3. 7. Model-Based Control of Gasoline Partially Premixed Combustion

   Författare :Gabriel Ingesson; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pressure-Sensor Feedback; Model Predictive Control; Model-Based Controller Design; Partially Premixed Combustion;

   Sammanfattning : Partially Premixed Combustion (PPC) is an internal combustion engine concept that aims to yield low NOx and soot emission levels together with high engine efficiency. PPC belongs to the class of low temperature combustion concepts where the ignition delay is prolonged in order to promote the air-fuel-mixture homogeneity in the combustion chamber at the start of combustion.

4. 8. Modeling and Control of the Open Plate Reactor

   Författare :Staffan Haugwitz; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process control; process intensification; heat exchange reactor; mid-ranging control; extended Kalman filter; model predictive control;

   Sammanfattning : The focus of this thesis is on modeling and control of the Open Plate Reactor (OPR), a new heat exchange reactor being developed by Alfa Laval AB. It combines intensified mixing with enhanced heat transfer capacity into one operation. LÄS MER

5. 9. Modelling, Analysis, and Control Aspects of a Rotating Power Electronic Brushless Doubly-Fed Induction Generator

   Författare :Naveed ur Rehman Malik; Chandur Sadarangani; Torbjörn Thiringer; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brushless doubly-fed induction generator; dual vector control; dynamic model; induction machine; internal model control; Lindmark concept; low-voltage ride-through; passive resistive network; rotating power electronic converter; rotating exciter; symmetrical faults; synchronous machine; thermal model; unity power factor; unsymmetrical faults; vector control; wind turbines.; Electrical Engineering; Elektro- och systemteknik; Energy Technology; Energiteknik;

   Sammanfattning : This thesis deals with the modeling, analysis and control of a novel brushlessgenerator for wind power application. The generator is named as rotatingpower electronic brushless doubly-fed induction machine/generator (RPEBDFIM/G).A great advantage of the RPE-BDFIG is that the slip power recoveryis realized in a brushless manner.

7. 10. Predictive Control of HCCI Engines Using Physical Models

   Författare :Anders Widd; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control; HCCI engine; engine control;

   Sammanfattning : Homogeneous Charge Compression Ignition (HCCI) is a promising internal combustion engine concept. It holds promise of combining low emission levels with high efficiency. However, as ignition timing in HCCI operation lacks direct actuation and is highly sensitive to operating conditions and disturbances, robust closed-loop control is necessary. LÄS MER
