    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Timing jitter; Stochastic parameters; Stochastic control; Real-time systems; Linear quadratic control; Jump linear systems; Distributed computer control systems; Clock synchronization; Delay compensation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : Control loops that are closed over a communication network get more and more common. A problem with such systems is that the transfer delays will be varying with different characteristics depending on the network hardware and software. LÄS MER

  3. 3. On robust and optimal control : with real time aspects

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Torbjörn Norlander; Luleå tekniska universitet.; [1997]
    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

  4. 4. 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; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [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

  5. 5. Integrated Control and Real-Time Scheduling

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

    Författare :Anton Cervin; Lunds universitet.; Lund University.; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotteknik; Automatiska system; reglerteknik; Automation; robotics; control engineering;

    Sammanfattning : The topic of the thesis is codesign of flexible real-time control systems. Integrating control theory and real-time scheduling theory, it is possible to achieve higher resource utilization and better control performance. The integration requires new tools for analysis, design, and implementation. LÄS MER
