2. 1. Embedded Systems and FPGAs for Implementation of Control Oriented Models, Applied to Combustion Engines

   Author : Carl Wilhelmsson; Förbränningsmotorer; []
   Keywords : NOx; NO; Nitrogen Oxides; Emissions; Air pollution; Algorithms; Physical model; Mathematical model; FPGA; Field Programmable Gate Arrays; Embedded Systems; Micro-controllers; Engine; Diesel Engine; Internal Combustion Engine; Combustion Control; Engine Control.;

   Abstract : Performance demands put on combustion engines are ever increasing, e.g. demands on emissions and fuel consumption. The increased demands together with new combustion concepts increase the need for feedback engine and combustion control. READ MORE

4. 2. Diesel Engine Modeling for Engine Management System Development

   Author : Markus Grahn; Chalmers University of Technology; []
   Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Engine control; Diesel engines; Engine management system; Emissions; Simulation; Optimization; Modeling;

   Abstract : Due to increasingly strict emission legislation and stronger demands on fuel consumption, typical passenger car diesel engines become increasingly complex with more and more controllable systems added. These added systems open up for the possibility to operate the engine at more efficient conditions, but it also becomes more challenging to optimize the settings in the engine management system.

5. 3. Model-Based Diesel Engine Management System Optimization - A Strategy for Transient Engine Operation

   Author : Markus Grahn; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Engine management system; Modeling; Engine control; Diesel engine; Fuel Consumption; Optimization; Emissions; Calibration; Simulation;

   Abstract : To meet increasingly strict emission legislation and stronger demands on fuel consumption, typical passenger car diesel engines become increasingly complex with more and more controllable systems added. These added systems open up for the possibility to operate the engine at more efficient conditions, but it also becomes more challenging to optimize the settings in the engine management system.

6. 4. Control of EGR and VGT for emission control and pumping work minimization in diesel engines

   Author : Johan Wahlström; Lars Nielsen; Lars Eriksson; Tore Hägglund; Linköpings universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mean value modeling; Oxygen fuel ratio; EGR-fraction; System analysis; Sign reversal; PID-control; European Transient Cycle; Automatic control; Reglerteknik;

   Abstract : Legislators steadily increase the demands on lowered emissions from heavy duty vehicles. To meet these demands it is necessary to integrate technologies like Exhaust Gas Recirculation (EGR) and Variable Geometry Turbochargers (VGT) together with advanced control systems. READ MORE

7. 5. Observer Design and Model Augmentation for Bias Compensation with Engine Applications

   Author : Erik Höckerdal; Erik Frisk; Tomas McKelvey; Linköpings universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Estimation; observer; bias compensation; diesel engine; EKF; Automatic control; Reglerteknik;

   Abstract : Control and diagnosis of complex systems demand accurate knowledge of certain quantities to be able to control the system efficiently and also to detect small errors. Physical sensors are expensive and some quantities are hard or even impossible to measure with physical sensors. This has made model-based estimation an attractive alternative. READ MORE
