  1. 6. Quality of control and real-time scheduling : allowing for time-variations in computer control systems

    Författare :Martin Sanfridson; KTH; []
    Nyckelord :real-time scheduling; sampled-data control. Performance measure; quality of control;

    Sammanfattning : The majority of computers around us are embedded in productsand dedicated to perform certain tasks. A specific task is thecontrol of a dynamic system. The computers are ofteninterconnected by communication networks forming a distributedsystem. LÄS MER

  3. 7. Real-Time Certified MPC : Reliable Active-Set QP Solvers

    Författare :Daniel Arnström; Daniel Axehill; Anders Hansson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In Model Predictive Control (MPC), optimization problems are solved recurrently to produce control actions. When MPC is used in real time to control safety-critical systems, it is important to solve these optimization problems with guarantees on the worst-case execution time. LÄS MER

  4. 8. On robust and optimal control : with real time aspects

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

    Sammanfattning : This thesis deals with several issues in realistic design of control systems, both from a practical and a theoretical point of view. This is done in three papers which are preceded by an introduction and a short discussion on future research on time-varying delays. The first paper discusses the importance of reliable sensors in control systems. LÄS MER

  5. 9. Real Time Drag Minimization

    Författare :Marianne Jacobsen; Ulf Ringertz; Anders Forsgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aeronautics; optimization; experimental verification; Vehicle engineering; Farkostteknik;

    Sammanfattning : This thesis focuses on the use of multiple redundant control surfaces to increase performance during flight. There is no clear-cut definition of performance. It may differ between applications, but here, the amount of drag for a given flight condition is used. LÄS MER
