  2. 11. On Pose Estimation in Room-Scaled Environments

    Author : Hanna E. Nyqvist; Gustaf Hendeby; Fredrk Gustafsson; Isaac Skog; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Pose (position and orientation) tracking in room-scaled environments is an enabling technique for many applications. Today, virtual reality (vr) and augmented reality (ar) are two examples of such applications, receiving high interest both from the public and the research community. READ MORE

  4. 12. Autonomous and Cooperative Landings Using Model Predictive Control

    Author : Linnea Persson; Bo Wahlberg; Tor Arne Johansen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooperative control; autonomous landings; rendezvous; UAV; drone; USV; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Cooperation is increasingly being applied in the control of interconnected multi-agent systems, and it introduces many benefits. In particular, cooperation can improve the efficiency of many types of missions, and adds flexibility and robustness against external disturbances or unknown obstacles. READ MORE

  5. 13. A Nonlinear Optimization Approach to H2-Optimal Modeling and Control

    Author : Daniel Petersson; Johan Löfberg; Lennart Ljung; Roland Toth; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model reduction; LPV system; linear parameter varying; controller; control synthesis; H2; H2-norm; nonlinear optimization;

    Abstract : Mathematical models of physical systems are pervasive in engineering. These models can be used to analyze properties of the system, to simulate the system, or synthesize controllers. However, many of these models are too complex or too large for standard analysis and synthesis methods to be applicable. READ MORE

  6. 14. Hydrobatics: Real-time Control, Simulation and Learning for Underactuated AUVs in Agile Maneuvers

    Author : Sriharsha Bhat; Ivan Stenius; Dimos V. Dimarogonas; Massimo Caccia; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; utonomous Underwater Vehicles; Underactuated Systems; Model Predictive Control; Hybrid Systems; Simulation; System Identification; Adaptive Sampling; Cyber-physical Systems.; Autonoma Undervattensfarkoster AUV ; Modellering; Simulering; Modelprediktiv kontroll MPC ; Systemidentifiering; Adaptiv mätning; Fältförsök; Cyber-fysikaliska System CPS .; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : The term hydrobatics refers to the agile maneuvering of underwater vehicles. Underwater robots such as autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs) are either designed as flight style, optimized for range and speed, or hover style, optimized for precise maneuverability.

  7. 15. Active Control of Propeller-Induced Noise in Aircraft : Algorithms & Methods

    Author : Sven Johansson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active control of sound; active noise control; anc; actuator individual normalized filtered-x lms; filtered-x lms algorithm; newton algorithm; complex lms; multireference algorithm; leaky lms; control effort weighting; feedforward control; feedback contro;

    Abstract : In the last decade acoustic noise has become more and more regarded as a problem. In cars, boats, trains and aircraft, low-frequency noise reduces comfort. Lightweight materials and more powerful engines are used in high-speed vehicles, resulting in a general increase in interior noise levels. READ MORE
