  1. 11. Induction Machine Speed Estimation - Observations on Observers

    Författare :Bo Peterson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; robotics; Automation; Elektronik och elektroteknik; Electronics and Electrical technology; estimation; sensorless control; observer; induction machine; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : This work focuses on observers estimating flux linkage and speed for induction machines, mainly in the low speed region. With speed estimation, sensorless control is possible, meaning that the speed of induction machines without mechanical speed sensors can be controlled. LÄS MER

  3. 12. Transparency Mechanisms in HRI : Improving an observer’s understanding of social robots

    Författare :Sebastian Wallkötter; Ginevra Castellano; Rachid Alami; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; human-robot interaction; social robotics; transparency; explainability; legibility; modeling and simulating human; machine learning;

    Sammanfattning : During an interaction between a robot and its user, a robot may sometimes do things that the user finds unintuitive. This often happens because the user does not understand the robot’s intent, state, or policy well enough. LÄS MER

  4. 13. Observers and controllers for Takagi-Sugeno fuzzy systems

    Författare :Pontus Bergsten; Dimiter Driankov; Robert Babuska; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Sammanfattning : This thesis studies analysis and design issues for observers anc controllers for Takagi-Sugeno (TS) fuzzy systems. Many physical systems are nonlinear in nature and using the well known linear techniques for such systems may result in bad performance, and even instability. LÄS MER

  5. 14. Nonlinear observers with applications in the steel industry

    Författare :Andreas Johansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : Access to measurements is a necessity in most technical applications, in order to detect faults, monitor performance, or exercise control. In some cases, however, installing measurement equipment is very expensive or even impossible. In such a case, estimates can be produced instead. LÄS MER

  7. 15. Hybrid observers for systems with intrinsic pulse-modulated feedback

    Författare :Diana Yamalova; Alexander Medvedev; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : This licentiate thesis deals with a special class of hybrid systems, where the continuous linear part is controlled by an intrinsic impulsive feedback that contributes discrete dynamics. The impacting pulsatile feedback signal is not available for measurement and, therefore, has to be reconstructed. LÄS MER
