  2. 21. Motion planning and feedback control techniques with applications to long tractor-trailer vehicles

    Author : Oskar Ljungqvist; Daniel Axehill; Johan Löfberg; Sebastien Gros; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : During the last decades, improved sensor and hardware technologies as well as new methods and algorithms have made self-driving vehicles a realistic possibility in the near future. At the same time, there has been a growing demand within the transportation sector to increase efficiency and to reduce the environmental impact related to transportation of people and goods.

  4. 22. Control of permanent-magnet synchronous machines in automotive applications

    Author : Oskar Wallmark; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric drive; electric vehicle; fault tolerance; hybrid electric vehicle; inverter; in-wheel motor; loss minimization; permanent-magnet synchronous machine; phase-locked loop; position estimation; sensorless control; vector control;

    Abstract : This thesis deals with the design and analysis of control system structures for electric drives equipped with permanent-magnet synchronous machines (PMSMs) in automotive applications. Sensorless control, meaning vector control without a mechanical rotor position sensor, is considered and a speed and position estimator of phase-locked loop type is analyzed thoroughly. READ MORE

  5. 23. On Trajectory Generation for Robots

    Author : Mahdi Ghazaei; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Haptic Interface; Fixed-Time Point-to-Point Trajectory Generation; Online Trajectory Generation; Dynamic Simulation and Optimization; Dynamics with Varying Contacts; Iterative Learning Control;

    Abstract : A fundamental problem in robotics is the generation of motion for a task. How to translate a task to a set of movements is a non-trivial problem. READ MORE

    Author : David A. Anisi; Xiaoming Hu; Randal Beard; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surveillance Missions; Minimum-Time Surveillance; Unmanned Ground Vehicles; Connectivity Constraints; Combinatorial Optimization; Computational Optimal Control; Receding Horizon Control; Mission Uncertainty; Safety; Task Completion; Adaptive Grid Methods; Missile Guidance; Nonlinear Observer Design; Active Observers; Non--uniformly Observable Systems; Mobile Robotic Systems; Intrinsic Observers; Differential Geometric Methods; Euler-Lagrange Systems; Contraction Analysis.; Optimization; systems theory; Optimeringslära; systemteori; Applied mathematics; Tillämpad matematik;

    Abstract : The main body of this thesis consists of six appended papers. In the  first two, different  cooperative surveillance problems are considered. The second two consider different aspects of the trajectory planning problem, while the last two deal with observer design for mobile robotic and Euler-Lagrange systems respectively. READ MORE

  7. 25. Identification and Synthesis of Components for Vibration Transfer Path Analysis

    Author : Per Sjövall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensor placement; Indirect sensing; Vibration control; System identification; Experimental methods; Substructuring; Kalman filter; Transfer path analysis; State-space models;

    Abstract : Transmission of structure-borne vibrations in built-up structures, e.g. vehicles such as aircraft, automobiles and trains, is addressed. Methodologies for modeling, analysis, prediction and reduction of vibrations are developed. READ MORE
