  1. 6. Linear Model Predictive Control : Stability and Robustness

    Författare :Johan Löfberg; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Most real systems are subjected to constraints, both on the available control effort and the controlled variables. Classical linear feedback is in some cases not enough for such systems. This has motivated the development of a more complicated, nonlinear controller, called model predictive control, MPC. LÄS MER

  3. 7. Minimax Approaches to Robust Model Predictive Control

    Författare :Johan Löfberg; Torkel Glad; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MPX; Minimax algorithms;

    Sammanfattning : Controlling a system with control and state constraints is one of the most important problems in control theory, but also one of the most challenging. Another important but just as demanding topic is robustness against uncertainties in a controlled system. LÄS MER

  4. 8. Collagenous colitis : A study of epidemiology, etiology, clinical features and treatment

    Författare :Johan Bohr; Robert Löfberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Collagenous colitis (CC) is characterised clinically by chronic watery diarrhoea and histopathologically by an increased submucosal collagen layer. An epidemiologic study of CC during 1984 to 1993 showed a female:male ratio of 9:1. The median age at diagnosis was 64 (28-78) years. The prevalence was 15. LÄS MER

  7. 10. Control, Models and Industrial Manipulators

    Författare :Erik Hedberg; Johan Löfberg; Mikael Norrlöf; Anders Robertsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The two topics at the heart of this thesis are how to improve control of industrial manipulators and how to reason about the role of models in automatic control.On industrial manipulators, two case studies are presented. LÄS MER
