  1. 1. Optimization Methods for Robust Control with Application to Resistive Wall Modes in Tokamaks

    Författare :Carl-Magnus Fransson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H?; fusion; QFT; performance; tokamak; optimization; robustness; structured singular value; control; plasma; resistive wall modes; LMI; PID control;

    Sammanfattning : In many research areas physical systems are described by mathematical models. We focus here on systems that are regulated by a controller, typically realized by software, whose design involves certain parameters. LÄS MER

  3. 2. Control of Systems with Limited Capacity

    Författare :Stefan Solyom; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; voltage collapse; power systems; anti-windup; piecewise linear systems; synthesis; ABS; PID control; LMI; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : Virtually all real life systems are such that they present some kind of limitation on one or many of its variables, physical quantities. These systems are designated in this thesis as systems with limited capacity. This work is treating control related problems of a subclass of such systems, where the limitation is a critical factor.

  4. 3. Synthesis of a Model-based Tire Slip Controller

    Författare :Stefan Solyom; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LMI; synthesis; hybrid; piecewise linear; ABS; PID;

    Sammanfattning : The Anti-lock Braking System (ABS) is an important component of a complex steering system for the modern car. In the latest generation of brake-by-wire systems, the performance requirements on the ABS have changed. The controllers have to be able to maintain a specified tire slip for each wheel during braking. LÄS MER

  7. 5. Robust observer design for a class of nonlinear systems: LMI approach

    Författare :Saleh Sayyaddelshad; Sophie Tarbouriech; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : Observer design for nonlinear systems is a well-known problem in control theory that has been studied from different perspectives. Because the system state variables are generally not always available, state estimation is an essential task in many control applications, which is why this problem has attracted considerable attention from researchers and is the main focus of this thesis.
