  1. 6. On model based aero engine diagnostics

    Författare :Mikael Stenfelt; Konstantinos Kyprianidis; Asteris Apostolidis; Mälardalens universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aero engines; model based diagnostics; gas path analysis; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Maintenance and diagnostics play a vital role in the aviation sector. This is especially true for the engines, being one of the most vital components. Lack of maintenance, or poor knowledge of the current health status of the engines, may lead to unforeseen disruptions and possibly catastrophic effects. LÄS MER

  3. 7. Parallel computing in model-based process engineering

    Författare :Niklas Andersson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parallel computing; Parameter estimation; Optimisation; Parameter selection; Model-based engineering;

    Sammanfattning : Chemical processes are usually expensive to run. To optimise a process, we need to know how the process behaves, and this is usually accomplished by studying the process experimentally. However, experiments are very expensive, particularly if an existing plant has to shut down normal operation to conduct an experiment. LÄS MER

  4. 8. Model-Based Diesel Engine Management System Optimization - A Strategy for Transient Engine Operation

    Författare :Markus Grahn; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engine management system; Modeling; Engine control; Diesel engine; Fuel Consumption; Optimization; Emissions; Calibration; Simulation;

    Sammanfattning : 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.

  5. 9. Adaptive model-based battery management - Predicting energy and power capability

    Författare :Björn Fridholm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; state-of-charge estimation; state estimation; lithium-ion batteries; Battery management; parameter estimation;

    Sammanfattning : The battery is the limiting system for automotive electrication due to cost, size, and uncertain degradation. To be competitive the battery must therefore be used optimally. LÄS MER

  7. 10. Distributed System Simulation Methods : For Model-Based Product Development

    Författare :Robert Braun; Petter Krus; Nigel Johnston; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Distributed system simulation can increase performance, re-usability and modularity in model-based product development. This thesis investigates four aspects of distributed simulation: multi-threaded simulations, simulation tool coupling, distributed equation solvers and parallel optimization algorithms. LÄS MER
