  1. 11. A Stochastic Control Approach to Include Transfer Limits in Power System Operation

    Författare :Magnus Perninge; Lennart Söder; Christopher DeMarco; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Frequency control; power regulating market; power system operation; power system security; stochastic impulse control; transfer capacity; transfer limit;

    Sammanfattning : The main function of the power grid is to transfer electric energy from generating facilities to consumers. To have a reliable and economical supply of electricity, large amounts of electric energy often have to be transferred over long distances. LÄS MER

  3. 12. Causal MMSE Filters for Personal Audio : A Polynomial Matrix Approach

    Författare :Simon Widmark; Mikael Sternad; Anders Ahlén; Lars-Johan Brännmark; Fredrik Gustafsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Personal Audio; Audio Pre-compensators; Causal Filters; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : This thesis is devoted to the study of synthesis of causal filters for generating personal sound zones. Personal sound zones, personal audio or personal sound is the theory and practice of steering sound in such a way that it is amplified in one region and suppressed in another. LÄS MER

  4. 13. Hybrid observers for systems with intrinsic pulse-modulated feedback

    Författare :Diana Yamalova; Alexander Medvedev; Xiaoming Hu; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid systems; impulsive systems; biomedical systems; Goodwin s oscillator; observers; time-delay; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : Dynamical processes resulting from the interaction of continuous and discrete dynamics are often encountered in living organisms. Time evolutions of such processes constitute continuous variables that are subject to instant changes at discrete points of time. LÄS MER

  5. 14. Millimeter-Wave Impulse Radio

    Författare :Mats Ärlelid; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compound semiconductor; resonant tunneling diode; ultra wideband; 60 GHz; on-off keying; transmitter; receiver; and super-regenerative oscillator;

    Sammanfattning : This thesis investigates the opportunity of wireless multi-gigabit per second communication at the millimeter-wave (mmW) frequencies around 60 GHz by using impulse radio and nanoelectronics. Today most wireless communication take place in the microwave region, where several different systems and applications are crowding the narrow-band channels. LÄS MER

  7. 15. High dynamic stiffness nano-structured composites for vibration control : A Study of applications in joint interfaces and machining systems

    Författare :Qilin Fu; Cornel-Mihai Nicolescu; Per Nylén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vibration control; High dynamic stiffness; Metal matrix composite; Nano structures; Plasma enhanced chemical vapour deposition PECVD ; High power impulse magnetron sputtering HiPIMS ; Adiabatic; Machining; Regenerative tool chatter; Production Engineering; Industriell produktion;

    Sammanfattning : Vibration control requires high dynamic stiffness in mechanical structures for a reliable performance under extreme conditions. Dynamic stiffness composes the parameters of stiffness (K) and damping (η) that are usually in a trade-off relationship. This thesis study aims to break the trade-off relationship. LÄS MER
