  1. 1. Event-Based Control and Estimation with Stochastic Disturbances

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

    Författare :Toivo Henningsson; Lund University.; Lunds universitet.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; event-based control; stochastic control; event-based estimation; control over networks; quantized measurements; sporadic control; embedded control;

    Sammanfattning : This thesis deals with event-based control and estimation strategies, motivated by certain bottlenecks in the control loop. Two kinds of implementation constraints are considered: closing one or several control loops over a data network, and sensors that report measurements only as intervals (e.g. with quantization).

  2. 2. Piecewise Linear Control Systems

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

    Författare :Mikael Johansson; Lund University.; Lunds universitet.; [1999]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piecewise quadratic functions; Linear matrix inequalities; Convex optimization; Optimal control; Performance analysis; Piecewise linear Lyapunov functions; Piecewise quadratic Lyapunov functions; Quadratic stability; Lyapunov stability; Piecewise linear systems; Nonlinear systems; Fuzzy systems; Hybrid systems.; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : This thesis treats analysis and design of piecewise linear control systems. Piecewise linear systems capture many of the most common nonlinearities in engineering systems, and they can also be used for approximation of other nonlinear systems. LÄS MER

  3. 3. Stochastic Event-Based Control and Estimation

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

    Författare :Toivo Henningsson; Lund University.; Lunds universitet.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; event-based control; event-based estimation; sporadic control; stochastic control; stochastic hybrid systems; sum-of-squares methods; control over networks; quantized measurements;

    Sammanfattning : Digital controllers are traditionally implemented using periodic sampling, computation, and actuation events. As more control systems are implemented to share limited network and CPU bandwidth with other tasks, it is becoming increasingly attractive to use some form of event-based control instead, where precious events are used only when needed.

  4. 4. Optimal Decisions with Limited Information

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

    Författare :Ather Gattami; Lund University.; Lunds universitet.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; systems; numerical analysis; Computer science; Convex Optimization; Graph Theory; Team Decision Theory; Game Theory; control; Datalogi; numerisk analys; system; kontroll; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : This thesis considers static and dynamic team decision problems in both stochastic and deterministic settings. The team problem is a cooperative game, where a number of players make up a team that tries to optimize a given cost induced by the uncertainty of nature. LÄS MER

  5. 5. Modeling, Control and Optimization of a Plate Reactor

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

    Författare :Staffan Haugwitz; Lund University.; Lunds universitet.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mid-ranging control; transition control; start-up; exothermic reaction; chemical reactor; modeling; process control; optimization; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : A new chemical reactor, the Alfa Laval Plate Reactor, is being developed by Alfa Laval, a Swedish world-leading heat exchanger company. The plate reactor combines the high-heat-transfer capabilities of plate heat exchangers with the efficient mixing and reaction control typical of microreactors. LÄS MER
