1. 1. Feed-forward Control and Dynamic Modelling in Temperature Control of Buildings

   Författare :Mohsen Soleimani-Mohseni; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building models; state space models; feedback; thermostats; transfer function models; intelligent buildings; ON-OFF controllers; Feed-forward; PIL controllers;

   Sammanfattning : This thesis is mainly about the investigations of different control strategies (and in particular feed-forward) in order to improve indoor climate and/or save energy in buildings. One part of the thesis deals with different ways to obtain dynamic models for climate systems in buildings. LÄS MER

   Sammanfattning : Filtering and reconstruction of signals play a fundamental role in modern signal processing, telecommunications, and control theory and are used in numerous applications. The feedback principle is an important concept in control theory. LÄS MER

5. 4. Nonlinear Modeling and Feedback Control of Drug Delivery in Anesthesia

   Författare :Margarida M. Silva; Alexander Medvedev; Teresa Mendonça; Torbjörn Wigren; Robain De Keyser; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anesthesia; drug delivery; feedback control; nonlinear modeling; pharmacokinetics pharmacodynamics; PID control; system identification; Wiener model; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : General anesthesia is a drug-induced reversible state where neuromuscular blockade (NMB), hypnosis, and analgesia (jointly denoted by depth of anesthesia - DoA) are guaranteed. This thesis concerns mathematical modeling and feedback control of the effect of the muscle relaxants atracurium and rocuronium, the hypnotic propofol, and the analgesic remifentanil. LÄS MER

7. 5. Closed-Loop Combustion Control of a Multi Cylinder HCCI Engine using Variable Compression Ratio and Fast Thermal Management

   Författare :Göran Haraldsson; Förbränningsmotorer; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CR; Motorer; framdrivningssystem; Motors and propulsion systems; Teknik; Technological sciences; Closed-Loop Combustion Control; CLCC; Multi cylinder; HCCI; Black box; System identification; State feedback; PID; LQG; Fast Thermal Management; FTM; VCR Variable Compression Ratio;

   Sammanfattning : The current Spark Ignited (SI) engine equipped with three-way catalyst offers low emissions, but has low efficiency at part load, which results in unnecessarily high CO2 emissions. The Compression Ignited (CI) engines have higher efficiency and hence lower CO2 emissions, but suffer from higher Nitrogen Oxide (NOx) and Particulate Matter (PM) emissions, and no three-way catalyst can be used.
