  2. 1. Emittance preservation and luminosity tuning in future linear colliders

    Author : Peder Eliasson; Tord Ekelöf; Grahame Blair; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; linear colliders; CLIC; ILC; emittance preservation; luminosity tuning; beam-based alignment; dispersion free steering; tuning bumps; trajectory feedback; static imperfections; dynamic imperfections; jitter; ground motion; ATL model; multi-pulse emittance; curved tunnel; Elementary particle physics; Elementarpartikelfysik;

    Abstract : The future International Linear Collider (ILC) and Compact Linear Collider (CLIC) are intended for precision measurements of phenomena discovered at the Large Hadron Collider (LHC) and also for the discovery of new physics. In order to offer optimal conditions for such experiments, the new colliders must produce very-high-luminosity collisions at energies in the TeV regime. READ MORE

  4. 2. Automatic Controller Tuning using Relay-based Model Identification

    Author : Josefin Berner; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic tuning; Relay feedback; PID control; Model identification; Process control;

    Abstract : Proportional-integral-derivative (PID) controllers are very common in the process industry. In a regular factory there may be hundreds or thousands of them in use. READ MORE

  5. 3. Model-Based Optimization of Combustion-Engine Control

    Author : Gabriel Turesson; Institutionen för reglerteknik; []
    Keywords : 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;

    Abstract : 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.

  6. 4. State Estimation of Lithium-ion Batteries

    Author : Xiaolei Bian; Longcheng Liu; Jinying Yan; Huazhen Fang; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion battery; State of charge; State of health; Model-based method; Extended Kalman filter; Filter tuning; Fusion model; Chemical Engineering; Kemiteknik;

    Abstract : To guarantee the safety operation, the key states of lithium-ion battery, e.g., the state of charge and the state of health, must be estimated and monitored accurately. This thesis is mainly to develop models and algorithms to accurately and robustly estimate the key battery states, based on the available measurements i. READ MORE

  7. 5. Spectral Moment Problems : Generalizations, Implementation and Tuning

    Author : Enrico Avventi; Anders Lindquist; Giorgio Picci; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : Spectral moment interpolation find application in a wide array of use cases: robust control, system identification, model reduction to name the most notable ones. This thesis aims to expand the theory of such methods in three different directions. The first main contribution concerns the practical applicability. READ MORE
