  1. 1. Applications of Information Inequalities to Linear Systems : Adaptive Control and Security

    Författare :Ingvar Ziemann; Henrik Sandberg; Alexandre Proutiere; Nikolai Matni; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stochastic Adaptive Control; Machine Learning; Fisher Information; Secure Control; Fundamental Limitations; Reinforcement Learning; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : This thesis considers the application of information inequalities, Cramér-Rao type bounds, based on Fisher information, to linear systems. These tools are used to study the trade-offs between learning and performance in two application areas: adaptive control and control systems security. LÄS MER

  3. 2. Funnel-Based Control for Coupled Spatiotemporal Specifications

    Författare :Farhad Mehdifar; Dimos V. Dimarogonas; Charalampos P. Bechlioulis; Bayu Jayawardhana; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Funnel-Based Control; Prescribed Performance Control; Uncertain Nonlinear Systems; Time-Varying Output Constraints; Coupled Spatiotemporal Constraints; Formation Control; Multi-Agent Systems; Trattbaserad kontroll; föreskriven prestandakontroll; osäkra icke-linjära system; tidsvarierande utgångsbegränsningar; kopplade rumsliga begränsningar; formationskontroll; multiagentsystem; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In the past decade, the integration of spatiotemporal constraints into control systems has emerged as a crucial necessity, driven by the demand for enhanced performance, guaranteed safety, and the execution of complex tasks. Spatiotemporal constraints involve criteria that are dependent on both space and time, which can be represented by time-varying constraints in nonlinear control systems. LÄS MER

  4. 3. 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. 4. Dynamic Access Control for Industrial Systems

    Författare :Björn Leander; Hans Hansson; Aida Causevic; Sasikumar Punnekkat; Tomas Lindström; Marina Krotofil; Mälardalens universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cybersecurity; Industrial Automation and Control Systems; Industry 4.0; Access Control; Computer Science; datavetenskap;

    Sammanfattning : Industrial automation and control systems (IACS) are taking care of our most important infrastructures, providing electricity and clean water, producing medicine and food, along with many other services and products we take for granted. The continuous, safe, and secure operation of such systems are obviously of great importance. LÄS MER

  7. 5. Toward Secure and Reliable Networked Control Systems

    Författare :André Teixeira; Henrik Sandberg; Karl H. Johansson; Kameshwar Poolla; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Security and reliability are essential properties in Networked Control Systems (NCS), which are increasingly relevant in several important applications such as he process industry and electric power networks. The trend towards using non-proprietary and pervasive communication and information technology (IT) systems, such as the Internet and wireless communications, may result in NCS being vulnerable to cyber attacks.
