1. 21. Toward applications oriented optimal input design with focus on model predictive control

   Författare :Christian Larsson; Håkan Hjalmarsson; Cristian Rojas; James Welsh; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Modern control designs are, with few exceptions, in some way model based. In particular, predictive control has rapidly become a popular control strategy, implemented in a large number of industrial plants. Model predictive control (MPC) uses a model to predict the impact of future control inputs on the controlled plant. LÄS MER

3. 22. Estimation of Nonlinear Greybox Models for Marine Applications

   Författare :Fredrik Ljungberg; Martin Enqvist; Svante Gunnarsson; Håkan Hjalmarsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : As marine vessels are becoming increasingly autonomous, having accurate simulation models available is turning into an absolute necessity. This holds both for facilitation of development and for achieving satisfactory model-based control. LÄS MER

4. 23. Uncertainties in Neural Networks : A System Identification Approach

   Författare :Magnus Malmström; Fredrik Gustafsson; Isaac Skog; Daniel Axehill; Håkan Hjalmarsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural networks; uncertainty; system identification;

   Sammanfattning : In science, technology, and engineering, creating models of the environment to predict future events has always been a key component. The models could be everything from how the friction of a tire depends on the wheels slip  to how a pathogen is spread throughout society. LÄS MER

5. 24. Learning Sequential Decision Rules in Control Design: Regret-Optimal and Risk-Coherent Methods

   Författare :Matias I. Müller; Cristian R. Rojas; Håkan Hjalmarsson; Tom Oomen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Engineering sciences deal with the problem of optimal design in the face of uncertainty. In particular, control engineering is concerned about designing policies/laws/algorithms that sequentially take decisions given unreliable data. This thesis addresses two particular instances of optimal sequential decision making for two different problems. LÄS MER

7. 25. 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
