  1. 31. Dual control concepts for linear dynamical systems

    Författare :Mina Ferizbegovic; Håkan Hjalmarsson; Thomas B. Schön; Cristian R. Rojas; Roy Smith; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : We study simultaneous learning and control of linear dynamical systems. In such a setting, control policies are derived with respect to two objectives: i) to control the system as well as possible, given the current knowledge of system dynamics (exploitation), and ii) to gather as much information as possible about the unknown system that can improve control (exploration).

  3. 32. 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.

  4. 33. Optimization Methods for Robust Control with Application to Resistive Wall Modes in Tokamaks

    Författare :Carl-Magnus Fransson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H?; fusion; QFT; performance; tokamak; optimization; robustness; structured singular value; control; plasma; resistive wall modes; LMI; PID control;

    Sammanfattning : In many research areas physical systems are described by mathematical models. We focus here on systems that are regulated by a controller, typically realized by software, whose design involves certain parameters. LÄS MER

  5. 34. Optimisation and control of shear flows

    Författare :Antonios Monokrousos; Dan S. Henningson; Laurette Tuckerman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shear flows; flow control; optimal disturbances; Lagrange method; transition to turbulence; non-linear dynamics; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : Transition to turbulence and flow control are studied by means of numerical simulations for different simple shear flows. Linear and non-linear optimisation methods using the Lagrange multiplier technique are employed. LÄS MER

  7. 35. Optimal Switching Problems and Related Equations

    Författare :Marcus Olofsson; Kaj Nyström; Saïd Hamadène; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optimal switching; stochastic control; variational inequalities; backward stochastic differential equations; incomplete information; stochastic filtering; Mathematics; Matematik;

    Sammanfattning : This thesis consists of five scientific papers dealing with equations related to the optimal switching problem, mainly backward stochastic differential equations and variational inequalities. Besides the scientific papers, the thesis contains an introduction to the optimal switching problem and a brief outline of possible topics for future research. LÄS MER
