1. 11. Learning in the Loop : On Neural Network-based Model Predictive Control and Cooperative System Identification

   Författare :Rebecka Winqvist; Bo Wahlberg; Cristian R. Rojas; Axel Ringh; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Learning; Model Predictive Control; System Identification; Optimal Transport; Inlärning; Modellprediktiv reglering; Systemidentifiering; Optimal transport; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Inom reglerteknik har integrationen av maskininlärningsmetoder framträtt som en central strategi för att förbättra prestanda och adaptivitet hos styrsystem. Betydande framsteg har gjorts inom flera viktiga aspekter av reglerkretsen, såsom inlärningsbaserade metoder för systemidentifiering och parameterskattning, filtrering och brusreducering samt reglersyntes.

3. 12. Fixed structure LQ design with applications

   Författare :Torbjörn Norlander; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Sammanfattning : This thesis deals mainly with the problem of designing structure constrained controllers (or fixed structure control design) which is a problem that occurs in many industrial control applications. In process industry for example, almost all control loops are closed with commercial PI controllers (which have specified structures). LÄS MER

4. 13. Frequency Domain Identification of Continuous-Time Systems : Reconstruction and Robustness

   Författare :Jonas Gillberg; Lennart Ljung; Fredrik Gustafsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete-time domain; Frequency-domain identification; Signal processing; Frequency-domain; Automatic control; Reglerteknik;

   Sammanfattning : Approaching parameter estimation from the discrete-time domain is the dominating paradigm in system identification. Identification of continuous-time models on the other hand is motivated by the fact that modelling of physical systems often take place in continuous-time. LÄS MER

5. 14. Non-Uniform Sampling in Statistical Signal Processing

   Författare :Frida Eng; Fredrik Gustafsson; Paulo Ferreira; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; signal processing; sampling; stochastic analysis; frequency transform; Automatic control; Reglerteknik;

   Sammanfattning : Non-uniform sampling comes natural in many applications, due to for example imperfect sensors, mismatched clocks or event-triggered phenomena. Examples can be found in automotive industry and data communication as well as medicine and astronomy. LÄS MER

7. 15. Initialization Methods for System Identification

   Författare :Christian Lyzell; Lennart Ljung; Martin Enqvist; Magnus Jansson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Initialization methods; Regressor selection; Identifiability; Automatic control; Reglerteknik;

   Sammanfattning : In the system identification community a popular framework for the problem of estimating a parametrized model structure given a sequence of input and output pairs is given by the prediction-error method. This method tries to find the parameters which maximize the prediction capability of the corresponding model via the minimization of some chosen cost function that depends on the prediction error.
