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

    Författare :Toivo Henningsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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. Modelling, analysis and experimentation of a simple feedback scheme for error correction control

    Författare :Oscar Flärdh; Karl H. Johansson; Mikael Johansson; Bo Bernhardsson; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network Control; Error Correction; Multiple-Input Describing Function; Extremum Seeking Control; Sensor Network Experiments; Automatic control; Reglerteknik;

    Sammanfattning : Data networks are an important part in an increasing number of applications with real-time and reliability requirements. To meet these demands a variety of approaches have been proposed. Forward error correction, which adds redundancy to the communicated data, is one of them. LÄS MER

    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial process control; Networked control systems; Wireless network; Event-triggered control; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : To tackle the ever-growing demands on high-quality and cost-effective industrial production, recent developments in embedded sensing, wireless communication, and cloud computing offer great opportunities. Resource-aware reliable wireless communication and real-time control are needed to leverage these technologies. LÄS MER

  4. 4. Stochastic Event-Based Control and Estimation

    Författare :Toivo Henningsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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.

  5. 5. Fundamental Limitations of Distributed Feedback Control in Large-Scale Networks

    Författare :Emma Tegling; Henrik Sandberg; Ali Jadbabaie; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed control; Large-scale systems; networked control; decentralized control; fundamental limitations; networked systems; frequency control; smart grid; consensus; spatial invariance; power system dynamics; microgrids; vehicular formation systems; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Networked systems accomplish global behaviors through local feedback interactions. The purpose of a distributed control design is to select interaction rules and control protocols that achieve desired global control objectives. LÄS MER
