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

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

    Sammanfattning : 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. LÄS MER

  3. 17. Network Synchronization and Control Based on Inverse Optimality : A Study of Inverter-Based Power Generation

    Författare :Taouba Jouini; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networked systems; coupled oscillator synchronization; inverse optimal robust control; power systems; inverter control;

    Sammanfattning : This thesis dwells upon the synthesis of system-theoretical tools to understand and control the behavior of nonlinear networked systems. This work is at the crossroads of three topics: synchronization in coupled high-order oscillators, inverse optimal control and the application of inverter-based power systems. LÄS MER

  4. 18. Toward Cyber-Secure and Resilient Networked Control Systems

    Författare :André Teixeira; Henrik Sandberg; Karl H. Johansson; Kameshwar Poolla; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cyber Security; Resilience; Industrial Control Systems; Fault-Tolerant Systems; Risk Management; Cyber säkerhet; Resiliens; Industriella Styrsystem; Riskanalys; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Resilience is the ability to maintain acceptable levels of operation in the presence of abnormal conditions. It is an essential property in industrial control systems, which are the backbone of several critical infrastructures. LÄS MER

  5. 19. Design and Performance Analysis of Wireless Networked Control Systems

    Författare :Burak Demirel; Mikael Johansson; Luca Schenato; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control; switched systems; optimal control; event-triggered control;

    Sammanfattning : Networked control systems (NCSs) are distributed systems that use shared communication networks to exchange information between system components such as sensors, controllers and actuators. The networked control system architecture promises advantages in terms of increased flexibility, reduced wiring and lower maintenance costs, and is finding its way into a wide variety of applications, ranging from automobiles and automated highway systems to process control, and power distribution systems.

  7. 20. State-based Channel Access for a Network of Control Systems

    Författare :Chithrupa Ramesh; Karl Henrik Johansson; Henrik Sandberg; Joao Hespanha; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networked control; multiple access; event-based; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Wireless networked control systems use shared wireless links to communicate between sensors and controllers, and require a channel access policy to arbitrate access to the links. Existing multiple access protocols perform this role in an agnostic manner, by remaining insular to the applications that run over the network. LÄS MER
