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

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

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

    Abstract : 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. Stochastic Event-Based Control and Estimation

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

    Author : Toivo Henningsson; Lunds universitet.; Lund University.; [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.

  3. 3. On Robust Distributed Control of Transportation Networks

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

    Author : Gustav Nilsson; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2019-01-22]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Signal Control; Distributed Control; Routing; Transportation Networks; Network Flows;

    Abstract : With the ever-growing traffic demands, the transportation networks are getting more and more congested. While expanding these networks with more roads is both costly and in many cities not even feasible, the rapid development of new sensing and communication techniques has made it possible to perform control of transportation networks in real-time.

  4. 4. On performance limitations of large-scale networks with distributed feedback control

    University dissertation from Stockholm, Sweden : KTH Royal Institute of Technology

    Author : Emma Tegling; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; microgrids; platooning; vehicular formation; multi-agent systems; H2 norms; fundamental limitations; consensus; Distributed control; large-scale networks; oscillator networks; power networks; power system dynamics; system performance; spatially invariant systems; Electrical Engineering; Elektro- och systemteknik;

    Abstract : We address the question of performance of large-scale networks with distributed feedback control. We consider networked dynamical systems with single and double integrator dynamics, subject to distributed disturbances. We focus on two types of problems. First, we consider problems modeled over regular lattice structures. READ MORE

  5. 5. Architectures and Performance Analysis of Wireless Control Systems

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Burak Demirel; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; wireless networks; optimal control; time-delays; packet losses; linear-quadratic control; supervisory control; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Modern industrial control systems use a multitude of spatially distributed sensors and actuators to continuously monitor and control physical processes. Information exchange among control system components is traditionally done through physical wires. READ MORE
