2. 1. Closed-loop Identification : Methods, Theory, and Applications

   Author : Urban Forssell; Lennart Ljung; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : System identification deals with constructing mathematical models of dynamical systems from measured data. Such models have important applications in many technical and nontechnical areas, such as diagnosis, simulation, prediction, and control. READ MORE

4. 2. Source-channel coding for closed-loop control

   Author : Lei Bao; Mikael Skoglund; Karl Henrik Johansson; Fredrik Gunnarssson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimal control; joint source--channel coding; source-channel coding; joint coding and control; certainty equivalence; linear quadratic control; stochastic control; wireless sensor network; Telecommunication; Telekommunikation;

   Abstract : Networked embedded control systems are present almost everywhere. A recent trend is to introduce wireless sensor networks in these systems, to take advantage of the added mobility and flexibility offered by wireless solutions. In such networks, the sensor observations are typically quantized and transmitted over noisy links. READ MORE

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

   Author : Göran Haraldsson; Förbränningsmotorer; []
   Keywords : 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;

   Abstract : 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.

6. 4. Indirect System Identification for Unknown Input Problems : With Applications to Ships

   Author : Jonas Linder; Martin Enqvist; Fredrik Gustafsson; Alexandre Sanfelice Bazanella; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Model structure; Unknown inputs; Indirect input measurements; Physical models; Instrumental variable; Closed loop; Graybox model; Identifiability; Ship; Marine vessel; Operational safety; Inertial measurement unit;

   Abstract : System identification is used in engineering sciences to build mathematical models from data. A common issue in system identification problems is that the true inputs to the system are not fully known. In this thesis, existing approaches to unknown input problems are classified and some of their properties are analyzed. READ MORE

7. 5. Sequential Decision-Making for Drug Design: Towards closed-loop drug design

   Author : Hampus Gummesson Svensson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; de novo drug design; multi-armed bandits; active learning; reinforcement learning; reaction yield prediction;

   Abstract : Drug design is a process of trial and error to design molecules with a desired response toward a biological target, with the ultimate goal of finding a new medication. It is estimated to be up to 10^{60} molecules that are of potential interest as drugs, making it a difficult problem to find suitable molecules. READ MORE
