3. 17. Nonlinear System Identification and Control Applied to Selective Catalytic Reduction Systems

   Författare :Soma Tayamon; Bengt Carlsson; Torbjörn Wigren; Bo Egardt; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear identification; nonlinear control; selective catalytic reduction; NOx reduction; recursive prediction error method; feedback linearisation; multiple-model; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : The stringent regulations of emission levels from heavy duty vehicles create a demand for new methods for reducing harmful emissions from diesel engines. This thesis deals with the modelling of the nitrogen oxide (NOx) emissions from heavy duty vehicles using a selective catalyst as an aftertreatment system, utilising ammonia (NH3) for its reduction.

4. 18. Estimation and Control of Resonant Systems with Stochastic Disturbances

   Författare :Peter Nauclér; Torsten Söderström; Anders Robertsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration control; stochastic control; stochastic systems; feedforward control; Wiener filtering; Kalman filtering; wave separation; unbalance estimation; nonlinear regression; Automatic control; Reglerteknik;

   Sammanfattning : The presence of vibration is an important problem in many engineering applications. Various passive techniques have traditionally been used in order to reduce waves and vibrations, and their harmful effects. Passive techniques are, however, difficult to apply in the low frequency region. LÄS MER

5. 19. Geometric analysis of stochastic model errors in system identification

   Författare :Jonas Mårtensson; Håkan Hjalmarsson; Michel Gevers; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic Control; Automatic control; Reglerteknik;

   Sammanfattning : Models of dynamical systems are important in many disciplines of science, ranging from physics and traditional mechanical and electrical engineering to life sciences, computer science and economics. Engineers, for example, use models for development, analysis and control of complex technical systems. LÄS MER

7. 20. Managing Natural Language Requirements in Large-Scale Software Development

   Författare :Johan Natt och Dag; Institutioner vid LTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; system; numerisk analys; Datalogi; control; requirements engineering; requirements management; linguistic engineering; natural language requirements; software engineering; software product development; Computer science; numerical analysis; systems; kontroll;

   Sammanfattning : An increasing number of market- and technology-driven software development companies face the challenge of managing several thousands of requirements written in natural language. The large number of requirements causes bottlenecks in the requirements management process and calls for increased efficiency in requirements engineering. LÄS MER
