  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. Integrated Control and Real-Time Scheduling

    Författare :Anton Cervin; Institutionen för reglerteknik; []
    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

  4. 8. Flexible Scheduling Methods and Tools for Real-Time Control Systems

    Författare :Dan Henriksson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control; Simulation Tools; Delay Compensation; Feedback Scheduling; Real-Time Control;

    Sammanfattning : This thesis deals with flexibility in the design of real-time control systems. By dynamic resource scheduling it is possible to achieve on-line adaptability and increased control performance under resource constraints. The approach requires simulation tools for control and real-time systems co-design. LÄS MER

  5. 9. Automatic memory management for flexible real-time systems

    Författare :Sven Robertz; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; feedback scheduling; embedded systems; real-time; memory management; garbage collection; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll;

    Sammanfattning : In a flexible real-time system, the constraints in available CPU time and memory lead to resource management problems, which must be handled carefully in order to maximize quality of service while avoiding overload. Managing CPU time -- scheduling -- is well studied and dynamic scheduling is widely accepted in the real-time industry. LÄS MER

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

    Författare :Anton Cervin; Institutionen för reglerteknik; []
    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
