  1. 1. Estimation and Detection with Applications to Navigation

    Author : David Törnqvist; Fredrik Gustafsson; Hugh Durrant-Whyte; Linköpings universitet; []
    Keywords : Navigation; SLAM; Particle Filter; Estimation; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The ability to navigate in an unknown environment is an enabler for truly utonomous systems. Such a system must be aware of its relative position to the surroundings using sensor measurements. It is instrumental that these measurements are monitored for disturbances and faults. READ MORE

  2. 2. Tire Modeling and Friction Estimation

    Author : Jacob Svendenius; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; Vehicle Dynamics; Wheel Speed; Brush Model; Combined Slip; Tire Models; Teknik; Friction Estimation;

    Abstract : New system technologies are continuously improving the performance of vehicles regarding comfort, stability, environmental stresses, and safety. Novel sensors are developed and used together with advanced control algorithms and faster and more accurate actuators to help the driver to maneuver the vehicle in a safer way. READ MORE

  3. 3. Multiantenna Cellular Communications : Channel Estimation, Feedback, and Resource Allocation

    Author : Emil Björnson; Björn Ottersten; Mats Bengtsson; Marios Kountouris; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; channel estimation; limited feedback; multicell communications; resource allocation;

    Abstract : The use of multiple antennas at base stations and user devices is a key component in the design of cellular communication systems that can meet the capacity demands of tomorrow. The downlink transmission from base stations to users is particularly limiting, both from a theoretical and a practical perspective, since user devices should be simple and power-efficient, and because many applications primarily create downlink traffic (e.

  4. 4. Design and Optimization of In-Cycle Closed-Loop Combustion Control with Multiple Injections

    Author : Carlos Jorques Moreno; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel Combustion; Pilot-Main Injection; Pilot Mass Estimation; Cylinder Volume Estimation; Bayesian Estimation; In-Cycle Combustion Controllability; In-Cycle Combustion Control; Model Predictive Combustion Control; Stochastic Combustion Optimization; Hardware Quantification;

    Abstract : With the increasing demand of transportation, biofuels play a fundamental role in the transition to sustainable powertrains. For the increased uncertainty of biofuel combustion properties, advanced combustion control systems have the potential to operate the engine with high flexibility while maintaining a high efficiency and robustness.

  5. 5. Quality Estimation of Approximate Models

    Author : Fredrik Tjärnström; Lennart Ljung; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis discusses three different topics: model error modeling, bootstrap, and model reduction. These subjects may at first sight seem to be quite far away from each other. However, there are some connections between them, the most importantone being uncertainty estimation.Model error modeling is actually a tool for model validation. READ MORE
