2. 1. Model-Based Control of Gasoline Partially Premixed Combustion

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

   Abstract : 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. 2. 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. Data-Rich Multivariable Control of Heavy-Duty Engines

   Author : Maria Henningsson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multivariable Control; Model Predictive Control; LQG Control; Virtual Sensing; System Identification; Diesel engines; HCCI engines; Dual-Fuel Combustion; Cylinder Pressure Sensors;

   Abstract : The combustion engine is today the dominant technology for transportation of goods and people world-wide. Concerns for global warming, toxic exhaust emissions, as well as cost and availability of fuel have in recent years created incentives for technological evolution of combustion engines. READ MORE

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

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

   Abstract : 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. READ MORE
