  2. 1. 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. 2. 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

  5. 3. On Parameter Estimation and Control of Time-Varying Stochastic Systems

    Author : Bengt Lindoff; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistics; Adaptive Predictive Control; Adaptive Stochastic Control; Dual Control; Convergence Analysis; Quadratic Forms; Forgetting Factor; Recursive Least Squares; Recursive Estimation; Linear Systems; Time-Varying Stochastic Systems; operations research; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

    Abstract : This thesis is about parameter estimation and control of time-varying stochastic systems. It can be divided into two parts. The first part deals with an estimation algorithm commonly used when estimating parameters in time-varying stochastic systems, the Recursive Least Squares (RLS) algorithm with forgetting factor.

  6. 4. Efficient Exploration and Robustness in Controlled Dynamical Systems

    Author : Alessio Russo; Alexandre Proutiere; Henrik Sandberg; Marcello Restelli; Nikolai Matni; Jana Tumova; Mikael Asplund; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforcement learning; efficient exploration; bandit algorithms; adversarial attacks; conformal prediction; data posioning; markov decision processes; attack detectability; optimal control; adaptive control; Electrical Engineering; Elektro- och systemteknik; Datalogi; Computer Science; Mathematical Statistics; Matematisk statistik;

    Abstract : In this thesis, we explore two distinct topics. The first part of the thesis delves into efficient exploration in  multi-task bandit models and model-free exploration in large Markov decision processes (MDPs). READ MORE

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

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

    Abstract : 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. READ MORE
