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

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

    Abstract : 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. READ MORE

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

    Author : Burak Demirel; Mikael Professor; Tamer Basar; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 8. The stochastic nature of intracellular control circuits

    Author : Johan Paulsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Stochastic; mesoscopic; noise; gene; plasmid; metabolic; regulation; control; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Chemical reactions are probabilistic by nature, causing random fluctuations inconcentrations to emerge spontaneously. In conventional (macroscopic) kinetics this internal noise is ignored under the assumption that average copy numbers are so high that fluctuations are negligible in comparison. READ MORE

  6. 9. Reinforcement Learning and Optimal Adaptive Control for Structured Dynamical Systems

    Author : Damianos Tranos; Alexandre Proutiere; Pontus Giselsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reinforcement Learning; Adaptive Control; Dynamical Systems; Control Theory; Control Engineering; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In this thesis, we study the related problems of reinforcement learning and optimal adaptive control, specialized to specific classes of stochastic and structured dynamical systems. By stochastic, we mean systems that are unknown to the decision maker and evolve according to some probabilistic law. READ MORE

  7. 10. Decentralized Control of Networked Systems : Information Asymmetries and Limitations

    Author : Farhad Farokhi; Karl Henrik Johansson; Jeff S. Shamma; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE
