  2. 1. Relay Feedback and Multivariable Control

    Author : Karl Henrik Johansson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Frequency methods; Process control; Sequential control; Automatic tuning; Control education; Laboratory process; Performance limitations; Decentralized control; Multivariable zero; Multivariable systems; Hybrid control; Nonlinear dynamics; Limit cycles; Oscillations; Relay feedback; Sliding modes; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : This doctoral thesis treats three issues in control engineering related to relay feedback and multivariable control systems. Linear systems with relay feedback is the first topic. Such systems are shown to exhibit several interesting behaviors. READ MORE

  4. 2. Design and Implementation of Resource-Aware Wireless Networked Control Systems

    Author : Jose Araujo; Karl Henrik Johansson; Anton Cervin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked Control Systems; Event-triggered Control; Event-triggered PI; aperiodic control;

    Abstract : Networked control over wireless sensor and actuator systems is of growing importancein many application domains. Energy and communication bandwidth are scarce resources in such systems. READ MORE

  5. 3. Source-channel coding for closed-loop control

    Author : Lei Bao; Mikael Skoglund; Karl Henrik Johansson; Fredrik Gunnarssson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimal control; joint source--channel coding; source-channel coding; joint coding and control; certainty equivalence; linear quadratic control; stochastic control; wireless sensor network; Telecommunication; Telekommunikation;

    Abstract : Networked embedded control systems are present almost everywhere. A recent trend is to introduce wireless sensor networks in these systems, to take advantage of the added mobility and flexibility offered by wireless solutions. In such networks, the sensor observations are typically quantized and transmitted over noisy links. READ MORE

  6. 4. Fast and Resource-Efficient Control of Wireless Cyber-Physical Systems

    Author : Dominik Baumann; Karl Henrik Johansson; Sebastian Trimpe; Manuel Mazo; KTH; []
    Keywords : Cyber-Physical Systems; Event-Triggered Control; Machine Learning; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Cyber-physical systems (CPSs) tightly integrate physical processes with computing and communication to autonomously interact with the surrounding environment.This enables emerging applications such as autonomous driving, coordinated flightof swarms of drones, or smart factories.

  7. 5. Modelling and Lagrangian control of mixed traffic: platoon coordination, congestion dissipation and state reconstruction

    Author : Mladen Čičić; Karl Henrik Johansson; Miroslav Krstić; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; traffic control; Lagrangian control; mixed traffic models; Intelligent Transportation Systems; Connected and Automated Vehicles; traffic congestion; platoon coordination; moving bottlenecks; bottleneck decongestion; stop-and-go wave dissipation; traffic state reconstruction; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Traffic congestion is a constantly growing problem, with a wide array of negative effects on the society, from wasted time and productivity to elevated air pollution and reduction of safety. The introduction of connected, autonomous vehicles enables a new, Lagrangian paradigm for sensing andcontrolling the traffic, by directly using connected vehicles inside the traffic flow, as opposed to the classical, Eulerian paradigm, which relies on stationary equipment on the road.
