  1. 1. Model-Based Vehicle Dynamics Control for Active Safety

    Författare :Brad Schofield; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Control Allocation; Vehicle Dynamics Control; Friction Estimation; Model-Based Control Design;

    Sammanfattning : The functionality of modern automotive vehicles is becoming increasingly dependent on control systems. Active safety is an area in which control systems play a pivotal role. Currently, rule-based control algorithms are widespread throughout the automotive industry. LÄS MER

  3. 2. Model Based Fault Diagnosis : Methods, Theory, and Automotive Engine Applications

    Författare :Mattias Nyberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Model based fault diagnosis is to perform fault diagnosis by means of models. An important question is how to use the models to construct a diagnosis system. To develop a general theory for this, useful in real applications, is the topic of the first part of this thesis. LÄS MER

  4. 3. Model Based Optimization of a Complete Diesel Engine/SCR System

    Författare :Claes Ericson; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MPC; model based optimization; real time models; model based control; SCR; optimization; EGR;

    Sammanfattning : Achieving upcoming emissions legislation (Euro VI) for heavy trucks is a serious challenge for the manufacturers. Apart from the increasingly strict limits on nitrogen oxides (NOx) and particulate emissions (PM), the limited amount of fossil fuels as well as alarming climate changes simultaneously drives the demand for low CO2 emissions.

  5. 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.

  7. 5. 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.
