  1. 1. Robust design : Accounting for uncertainties in engineering

    Author : David Lönn; Larsgunnar Nilsson; Niclas Strömberg; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robust optimisation; robust design; robustness; meta model; sensitivity analysis; Solid mechanics; Fastkroppsmekanik;

    Abstract : This thesis concerns optimization of structures considering various uncertainties. The overall objective is to find methods to create solutions that are optimal both in the sense of handling the typical load case and minimising the variability of the response, i.e. robust optimal designs.

  2. 2. Railway Infrastructure Robustness : Attributes, evaluation, assurance and improvement

    Author : Per Norrbin; Ragnar Hedström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Abstract : According to the European program Horizon 2020, multifaceted challenges in transportinfrastructure include 1) making infrastructure more resilient to keep pace with the increasing mobility needs; 2) reducing the impact of infrastructure on the environment;and 3) dealing with declining resources to maintain and upgrade transport infrastructure. New design and maintenance approaches must be developed to handle these issues, ascurrent methods are inadequate. READ MORE

  3. 3. Robust Sound Field Control for Audio Reproduction : A Polynomial Approach to Discrete-Time Acoustic Modeling and Filter Design

    Author : Lars-Johan Brännmark; Anders Ahlén; Mikael Sternad; Mathias Johansson; Rodney Kennedy; Uppsala universitet; []
    Keywords : Acoustic signal processing; equalizers; error modeling; feedforward control; interpolation; loudspeakers; multivariable filters; polynomials; robustness; sound fields;

    Abstract : This thesis is concerned with the design and analysis of robust discrete-time filters for audio equalization and sound field control in real reverberant environments. Inspired by methods in polynomial control theory, a unified framework for acoustic modeling and filter design is developed. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 5. Uncertainty, Robustness and Sensitivity Reduction in the Design of Single Input Control Systems

    Author : Kjell Nordström; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Uncertainty; Robustness; Sensitivity; Single input control systems;

    Abstract : Feedback control of systems modelled as single input, time invariant, linear and continuous time systems is the subject of this thesis. A growing interest in the design of feedback control systems that can cope with model uncertainties has been the motivation for the study. READ MORE
