1. 6. Control and Analysis of Pulse-Modulated Systems

   Författare :Stefan Almér; Ulf Jönsson; Gilead Tadmor; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pulse-width modulation; Periodic systems; Stability analysis; Harmonic analysis; Lyapunov methods; Dynamic phasors; Harmonic transfer function; Switched mode power converters; Sampled data modeling; H-infinity synthesis; Optimization; systems theory; Optimeringslära; systemteori;

   Sammanfattning : The thesis consists of an introduction and four appended papers. In the introduction we give an overview of pulse-modulated systems and provide a few examples of such systems. Furthermore, we introduce the so-called dynamic phasor model which is used as a basis for analysis in two of the appended papers. LÄS MER

4. 8. The Physical Environment and Occupant Thermal Perceptions in Office Buildings An Evaluation of Sampled Data from Five European Countries

   Författare :John Leland Stoops; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal sensation; Europe; thermal preference; seasonal variation; office buildings; temperature perception; outdoor temperature; interior temperature; field study; thermal comfort; Clo; Met; carbon dioxide;

   Sammanfattning : The results from a large field study of thermal comfort in European office buildings are reported. Measurements of physical environmental conditions and occupant perceptions were collected over sixteen months from twenty-six different office buildings located in France, Greece, Portugal, Sweden and the UK.

5. 9. Quality of control and real-time scheduling : allowing for time-variations in computer control systems

   Författare :Martin Sanfridson; KTH; []
   Nyckelord :real-time scheduling; sampled-data control. Performance measure; quality of control;

   Sammanfattning : The majority of computers around us are embedded in productsand dedicated to perform certain tasks. A specific task is thecontrol of a dynamic system. The computers are ofteninterconnected by communication networks forming a distributedsystem. LÄS MER

7. 10. Identification of Stochastic Continuous-time Systems : Algorithms, Irregular Sampling and Cramér-Rao Bounds

   Författare :Erik Larsson; Torsten Söderström; Bo Wahlberg; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

   Sammanfattning : The problem of identifying continuous-time systems is of fundamental interest in various areas, such as astrophysics, economics, control and signal processing. The most obvious reason for working with continuous-time models is that most physical systems are inherently continuous in time. LÄS MER
