    Sammanfattning : Event-based control is a promising concept for the design of resource-efficient feedback systems, where events such as sampling, actuation, and data transmissions are triggered reactively based on monitored control performance rather than a periodic timer. In this thesis, we investigate how sampling and communication events should be triggered to fully exploit the potential of event-based control based on the classic linear–quadratic–Gaussian (LQG) framework.

  5. 4. Frequency Analysis of Sampled-Data Systems Applied to a Lime Slaking Process

    Författare :Olof Lindgärde; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; periodic systems; intersample behavior; sampled-data system; lime slaking; multirate sampling; frequency analysis; tank reactor; product inhibited; modeling;

    Sammanfattning : Single-rate and multirate sampled-data (SD) systems as well as linear time periodic (LTP) systems with discrete jumps are analyzed in the frequency domain. The focus of the analysis is both on rejection of disturbances and on robust stability properties. LÄS MER

  7. 5. 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
