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

    Författare :Emma Tegling; Henrik Sandberg; Ali Jadbabaie; KTH; []
    Nyckelord :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

  3. 2. Decentralized Control of Networked Systems : Information Asymmetries and Limitations

    Författare :Farhad Farokhi; Karl Henrik Johansson; Jeff S. Shamma; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked Control Systems; Decentralized Control; Limited Model Information; Transportation Systems; Sensor Scheduling;

    Sammanfattning : Designing local controllers for networked systems is challenging, because in these systems each local controller can often access only part of the overall information on system parameters and sensor measurements. Traditional control design cannot be easily applied due to the unconventional information patterns, communication network imperfections, and design procedure complexities. LÄS MER

  4. 3. Compensating for Unreliable Communication Links in Networked Control Systems

    Författare :Erik Henriksson; Karl Henrik Johansson; Henrik Sandberg; Bruno Sinopoli; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networked control; packet loss compensation; unreliable communication; control over wirless networks; Automatic control; Reglerteknik;

    Sammanfattning : Control systems utilizing wireless sensor and actuator networks can be severely affectedby the properties of the communication links. Radio fading and interferencemay cause communication losses and outages in situations when the radio environmentis noisy and low transmission power is desirable. LÄS MER

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

    Författare :Burak Demirel; Mikael Professor; Tamer Basar; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. Control and Communication-Schedule Co-design For Networked Control Systems

    Författare :Masoud Bahraini; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control; Networked Control Systems; Robust Invariance; Communication Scheduling;

    Sammanfattning : In a networked control system (NCS), the control loop is closed through a communication medium. This means that sensor measurements and/or control signals can be exchanged through a communication link. LÄS MER
