  3. 3. Closed-Loop Control of HCCI Engine Dynamics

    University dissertation from Department of Automatic Control, Lund Institute of Technology (LTH)

    Author : Johan Bengtsson; Lund University.; Lunds universitet.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotteknik; Automatiska system; reglerteknik; Automation; robotics; control engineering;

    Abstract : The topic of the thesis is control of Homogeneous Charge Compression Ignition (HCCI) engine dynamics. HCCI offers a potential to combine high efficiency with very low emissions. In order to fulfill the potential benefits, closed-loop control is needed. READ MORE

  4. 4. Stochastic Event-Based Control and Estimation

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Toivo Henningsson; Lund University.; Lunds universitet.; [2012]
    Keywords : 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;

    Abstract : 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.

  5. 5. Closed-loop Identification : Methods, Theory, and Applications

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Urban Forssell; Linköpings universitet.; Linköpings universitet.; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : System identification deals with constructing mathematical models of dynamical systems from measured data. Such models have important applications in many technical and nontechnical areas, such as diagnosis, simulation, prediction, and control. READ MORE
