  1. 6. Learning flow functions : architectures, universal approximation and applications to spiking systems

    Författare :Miguel Aguiar; Karl H. Johansson; João Sousa; Maarten Schoukens; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Learning flow functions of continuous-time control systems is considered in this thesis. The flow function is the operator mapping initial states and control inputs to the state trajectories, and the problem is to find a suitable neural network architecture to learn this infinite-dimensional operator from measurements of state trajectories.

  3. 7. Fuel-Efficient Heavy-Duty Vehicle Platooning

    Författare :Assad Alam; Karl H. Johansson; Roberto Horowitz; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Platooning; Heavy-Duty Vehicle; Optimal Control; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The freight transport industry faces big challenges as the demand for transport and fuel prices are steadily increasing, whereas the environmental impact needs to be significantly reduced. Heavy-duty vehicle (HDV) platooning is a promising technology for a sustainable transportation system. LÄS MER

  4. 8. Defense of Cyber-Physical Systems Against Learning-based Attackers

    Författare :Rijad Alisic; Henrik Sandberg; Karl H. Johansson; Miroslav Pajic; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Control Theory; Security; Privacy; Machine Learning; Cyber-Physical Systems; Change Point Problems; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Cyberattacks against critical infrastructures pose a serious threat to society, as they can have devastating consequences on the economy, security, or public health. These infrastructures rely on a large network of cyber components, such as sensors, controllers, computers, and communication devices, to monitor and control their physical processes. LÄS MER

    Sammanfattning : Cyberattacks against critical infrastructures has been a growing problem for the past couple of years. These infrastructures are a particularly desirable target for adversaries, due to their vital importance in society. LÄS MER

  7. 10. Control of Multi-Agent Systems with Applications to Distributed Frequency Control Power Systems

    Författare :Martin Andreasson; Karl H. Johansson; Wei Ren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Multi-agent systems are interconnected control systems with many application domains. The first part of this thesis considers nonlinear multi-agent systems, where the control input can be decoupled into a product of a nonlinear gain function depending only on the agent's own state, and a nonlinear interaction function depending on the relative states of the agent's neighbors.
