  1. 1. Feedback Linux Scheduling and a Simulation Tool for Wireless Control

    Detta är en avhandling från Department of Automatic Control, Lund Institute of Technology, Lund University

    Författare :Martin Ohlin; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linux; Scheduling; Resource Reservation; Feedback Scheduling; Simulation Tools;

    Sammanfattning : Computing systems are becoming more and more complex and powerful. It is nowadays not uncommon to run several server applications on the same physical platform. This gives rise to a need for resource reservation techniques, so that administrators may prioritize some tasks, or customers, over others. LÄS MER

  2. 2. Cross-layer Aspects in OFMDA Systems Feedback, Scheduling and Beamforming

    Detta är en avhandling från Stockholm : KTH

    Författare :Patrick Svedman; KTH.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Information technology Telecommunication; TEKNIKVETENSKAP Informationsteknik Telekommunikation;

    Sammanfattning : This thesis mainly studies the downlink of a wireless multiuser system, where the transmitter has limited knowledge about the communication channels of the users. Key techniques to improve the performance of such systems are, for instance, multiple antennas, multiuser diversity and orthogonal frequency-division multiple access (OFDMA). LÄS MER

  3. 3. Towards the Integration of Control and Real-Time Scheduling Design

    Detta är en avhandling från Department of Automatic Control, Lund Institute of Technology (LTH)

    Författare :Anton Cervin; [2000]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-Time Control; Scheduling; Co-Design; Deadlines; Performance; Simulation; Feedback;

    Sammanfattning : The thesis deals with scheduler and controller co-design for real-time control systems. The overall goal is higher resource utilization and better control performance. One goal is to minimize the performance loss due to jitter and control delays. LÄS MER

  4. 4. Flexible Embedded Control Systems : Design and Implementation

    Detta är en avhandling från Department of Automatic Control, Lund Institute of Technology (LTH)

    Författare :Johan Eker; [1999]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automation; Feedback scheduling; Quality of service; Linear quadratic control; Toolbox; Simulation; Rapid prototyping; Programming language; Scheduling; Embedded systems; Real-time system; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : Embedded control system design is a complex and error prone task, and there is a great need for better development tools. Today most real-time control systems are static systems, designed in an ad-hoc fashion. A more interactive way of working would give shorter development times, reduced costs for testing, and safer, more robust systems. LÄS MER

  5. 5. LQG-Based Real-Time Scheduling and Control Codesign

    Detta är en avhandling från Department of Automatic Control, Lund Institute of Technology, Lund University

    Författare :Yang Xu; [2017-11-20]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LQG control; Real-time system; Scheduling; Time-delay system;

    Sammanfattning : Having multiple control tasks concurrently running on a single computing platform increases the processor utilization but degrades the control performance due to delay and jitter. In scheduling and control codesign, the objective is to optimize the combined performance of all the controllers, subject to a schedulability constraint. LÄS MER
