  1. 1. Using direct manipulation for real-time structural design exploration

    University dissertation from Lund University (Media-Tryck)

    Author : Daniel Åkesson; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interactive structural analysis; Very direct manipulation; Interactive structural form finding;

    Abstract : Before a new structure can be built, it must be designed. This design phase is a very important step in the building process. The total cost of the structure and its structural performance are largely dependent on the structural design process. The impact of decisions on the design process is initially high and declines as the design matures. READ MORE

  2. 2. Power System Damping - Structural Aspects of Controlling Active Power

    University dissertation from IEA, LTH, Box 118, SE-221 00 Lund, Sweden

    Author : Olof Samuelsson; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics and Electrical technology; controller interaction; mode controllability; mode observability; mechanical equivalent; linear differential-algebraic equations; modal analysis; active power; power system damping; electro-mechanical oscillations; Elektronik och elektroteknik; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : Environmental and economical aspects make it difficult to build new power lines and to reinforce existing ones. The continued growth in demand for electric power must therefore to a great extent be met by increased loading of available lines. READ MORE

  3. 3. On the Internal Dynamics and AC-Motor Drive Application of Modular Multilevel Converters

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Antonios Antonopoulos; Hans-Peter Nee; Lennart Harnefors; Hirofumi Akagi; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Capacitor-Voltage Control; Controller Interaction; Converter Control; Energy Balance; Lyapunov Stability; Medium-Voltage Drives; Modular Multilevel Converter; Modulation; Open-Loop Control; Optimization; Variable-Speed Drives; Voltage-Source Converter.; Energibalans; Kondensatorspänningsstyrning; Lyapunov-stabilitet; Mellan-spänning drivsystem; Modulation; Modulär multinivåomvandlare; Omvandlarstyrning; Optimering; Regulatorväxelverkan; Spänningsstyva omvandlare; Varvtalsstyrda motordrifter; Öppen styrning.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : This thesis is an effort to investigate the operation and the performanceof modular multilevel converters (M2Cs). Proven to be the most promisingtopology in high-voltage high-power applications, it is necessary to put aneffort in understanding the physical laws that govern the internal dynamicsof such converters, in order to design appropriate control methods.

  4. 4. A Petri net based unified representation for hardware/software co-design

    University dissertation from Linköping : Univ

    Author : Erik Stoy; [1995]

    Abstract : This thesis describes and defines a design representation model for hardware/software co-design. To illustrate its usefulness we show how designs captured in the representation can be repartitioned by moving functionality between hardware and software. READ MORE

  5. 5. Operator Interaction and Optimization in Control Systems

    University dissertation from Department of Automatic Control, Lund Institute of Technology (LTH)

    Author : Johan Åkesson; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grade Changes; JGrafchart; Dynamic Optimization; Operator support; Model Predictive Control; Integral Action;

    Abstract : The two themes of this thesis are operator interaction and optimization, primarily with application to complex plants in the process industry. Four important aspects that should be considered in the control system design for such plants are identified; safety, performance, operator interaction and operator acceptance. READ MORE
