2. 1. On some continuous-time modeling and estimation problems for control and communication

   Author : Yasir Irshad; Magnus Mossberg; Magnus Jansson; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System Identification; Parameter Estimation; Continuous-time Stochastic Systems; Networked Control Systems; Errors-in-variables Systems; Wireless Channel Modeling; Closed-loop Identification; Physics; Fysik;

   Abstract : The scope of the thesis is to estimate the parameters of continuous-time models used within control and communication from sampled data with high accuracy and in a computationally efficient way.In the thesis, continuous-time models of systems controlled in a networked environment, errors-in-variables systems, stochastic closed-loop systems, and wireless channels are considered.

4. 2. On Modeling and Nonlinear Model Reduction in Automotive Systems

   Author : Oskar Nilsson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear systems; model reduction; discrete-time; continuous-time;

   Abstract : The current control design development process in automotive industry and elsewhere involves many expensive experiments and hand-tuning of control parameters. Model based control design is a promising approach to reduce costs and development time. In this process low complexity models are essential and model reduction methods are very useful tools.

5. 3. Some problems of modeling and parameter estimation in continous-time for control and communication

   Author : Yasir Irshad; Magnus Mossberg; Magnus Jansson; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Continuous-time modeling; identification; estimation; closed-loop systems; networked control systems; wireless communication; stochastic differential equations; Physics; Fysik;

   Abstract : Stochastic system identification is of great interest in the areas of control and communication. In stochastic system identification, a model of a dynamic system is determined based on given inputs and received outputs from the system, where stochastic uncertainties are also involved. READ MORE

6. 4. Modeling and Simulation of Physical Systems in a Mechatronic Context

   Author : Carl-Johan Sjöstedt; Martin Törngren; Hans Vangheluwe; KTH; []
   Keywords : mechatronics; MATLAB Simulink; SysML; bond graphs; Modelica; Simscape; simulation; modeling; EAST-ADL2; physical modeling; Mechanical engineering; Maskinteknik;

   Abstract : This thesis gives different views on the modeling and simulation of physical systems, especially together with embedded systems, forming mechatronic systems. The main considered application domain is automotive. READ MORE

7. 5. Modeling financial volatility : A functional approach with applications to Swedish limit order book data

   Author : Suad Elezovic; Xavier de Luna; Gunnar Rosenqvist; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Financial data; functional time series; multivariate generalized least squares; seemingly unrelated autoregression; Statistics; computer and systems science; Statistik; data- och systemvetenskap; ekonometri; Econometrics;

   Abstract : This thesis is designed to offer an approach to modeling volatility in the Swedish limit order market. Realized quadratic variation is used as an estimator of the integrated variance, which is a measure of the variability of a stochastic process in continuous time. READ MORE
