   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; System identification; process control; Grey-box modelling; outlier detection; Statistics; computer and systems science; Statistik; data- och systemvetenskap;

   Sammanfattning : The contents of this thesis can be divided into two main parts. The first one is the development of an identification methodology for the modelling of complex industrial processes. The second one is the application of this methodology to the curl and twist problem. LÄS MER

3. 2. Nonlinear Identification and Control with Solar Energy Applications

   Författare :Linda Brus; Bengt Carlsson; Torbjörn Wigren; Graham C. Goodwin; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; feedforward control; model predictive control; nonlinear control; nonlinear systems; recursive identification; solar power; system identification; time delay systems; Automatic control; Reglerteknik; Reglerteknik; Automatic Control;

   Sammanfattning : Nonlinear systems occur in industrial processes, economical systems, biotechnology and in many other areas. The thesis treats methods for system identification and control of such nonlinear systems, and applies the proposed methods to a solar heating/cooling plant. LÄS MER

4. 3. System Identification of an Engine-load Setup Using Grey-box Model

   Författare :Neda Nickmehr; Jan Åslund; Tomas McKelvey; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : With the demand for more comfortable cars and reduced emissions, there is an increasing focus on model-based system engineering. Therefore, developing accurate vehicle models has become significantly important. The powertrain system, which transfers the engine torque to the driving wheels, is one of the most important parts of a vehicle. LÄS MER

5. 4. Nonlinear Structural Identification Using a Multi-Harmonic  Frequency Response Functions

   Författare :Vahid Yaghoubi Nasrabadi; Thomas Abrahamsson; Andreas Linderholt; Martin Magnevall; Chalmers; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear structure; inverse problem; grey box system identification; finite element model updating; identifiability; Fisher information matrix; multi-harmonic frequency response function; Maskinteknik; Mechanical Engineering;

   Sammanfattning : In industrial structural dynamics problems, linear FE-models commonly serve to represent the global structural behavior. However, when test data are available they often show evidence of nonlinear dynamic characteristics. In that case, an initial linear model may be judged insufficient in representing the dynamics of the structure. LÄS MER

7. 5. Recursive black-box identification of nonlinear state-space ODE models

   Författare :Linda Brus; Bengt Carlsson; Torbjörn Wigren; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : Nonlinear system identification methods is a topic that has been gaining interest over the last years. One reason is the many application areas in controller design and system development. However, the problem of modeling nonlinear systems is complex and finding a general method that can be used for many different applications is difficult. LÄS MER
