  1. 1. Real-Time Workload Models : Expressiveness vs. Analysis Efficiency

    Författare :Martin Stigge; Wang Yi; Sanjoy Baruah; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Real-time systems; task models; EDF; fixed-priority scheduling; schedulability analysis; response-time analysis; abstraction refinement; Computer Science with specialization in Real Time Systems; Datavetenskap med inriktning mot realtidssystem;

    Sammanfattning : The requirements for real-time systems in safety-critical applications typically contain strict timing constraints. The design of such a system must be subject to extensive validation to guarantee that critical timing constraints will never be violated while the system operates. LÄS MER

  3. 2. Configurable Hardware Support for Single Processor Real-Time Systems

    Författare :Susanna Nordström; Lars Asplund; Kristina Lundqvist; Krzysztof Kuchcinski; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; FPGA; real-time system; real-time kernel; RTOS; real-time operating system; vhdl; embedded system; Computer engineering; Datorteknik; Datavetenskap;

    Sammanfattning : This thesis describes a further development of a building block for programmable devices in embedded systems handling real-time functionality.Embedded systems are included in a variety of products within different technical areas such as industrial automation, consumer electronics, automotive industry, and communication-, and multimedia systems.

  4. 3. 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

  5. 4. 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

  7. 5. 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
