  1. 1. Modeling and Model Reduction in Automotive Systems

    Author : Oskar Nilsson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automotive systems; Lambda sensor; Model reduction; Modeling; Engine air path;

    Abstract : The current control design development process in automotive industry and elsewhere involves many expensive experiments and hand-tuning of control parameters. Model based control design is a promising approach to reduce costs and development time. In this process low complexity models are essential. READ MORE

  2. 2. Statistical Sensor Calibration Algorithms

    Author : Anas Alhashimi; Thomas Gustafsson; Damiano Varagnolo; Johan Sjöberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Abstract : The use of sensors is ubiquitous in our IT-based society; smartphones, consumer electronics, wearable devices, healthcare systems, industries, and autonomous cars, to name but a few, rely on quantitative measurements for their operations. Measurements require sensors, but sensor readings are corrupted not only by noise but also, in almost all cases, by deviations resulting from the fact that the characteristics of the sensors typically deviate from their ideal characteristics.

  3. 3. Machine Learning Based Methods for Virtual Validation of Autonomous Driving

    Author : Tobias Johansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AD Simulation; Virtual Validation; Sensor Error Modeling; Falsification; Autonomous Driving; Validation; Mixture Density Networks;

    Abstract : During the last decade, automotive manufacturers have introduced increasingly capable driving automation functions in consumer vehicles. As the functionality becomes more advanced, the task of driving moves from the human to the car. Hence, making sure that autonomous driving (AD) functions are reliable and safe is of high importance.

  4. 4. Implementation, identification, and adaptation of Preisach like hysteresis models

    Author : Marcus Hedegärd; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hysteresis modeling; adaptive hysteresis compensation.; generalized Prandtl-Ishlinskii model; Preisach model; magnetoelastic sensor;

    Abstract : The extended generalized Prandtl-Ishlinskii model (XGPI) of hysteresis has a wide applicability, partly because of its capability of modelling highly asymmetric hystereses. For a given parameterization, it is typically identified using non-linear least squares optimization with concomitant problems of convergence, dependence on initial parameter guess and local minima.

  5. 5. Automation of front-end loaders : electronic self leveling and payload estimation

    Author : I Yung; Leonid Freidovich; Sven Rönnbäck; Carlos Vázquez; Tomas Nygren; Heikki Handroos; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Front-End Loaders; Electronic Self Leveling; Modeling; Control; Disturbance estimation; Payload estimation; Equations of motion; Pressure-based friction;

    Abstract : A growing population is driving automatization in agricultural industry to strive for more productive arable land. Being part of this process, this work is aimed to investigate the possibility to implement sensor-based automation in a particular system called Front End Loader, which is a lifting arms that is commonly mounted on the front of a tractor.
