1. Linear Model Predictive Control : Stability and Robustness
Abstract : Most real systems are subjected to constraints, both on the available control effort and the controlled variables. Classical linear feedback is in some cases not enough for such systems. This has motivated the development of a more complicated, nonlinear controller, called model predictive control, MPC. READ MORE

2. Minimax Approaches to Robust Model Predictive Control
Abstract : Controlling a system with control and state constraints is one of the most important problems in control theory, but also one of the most challenging. Another important but just as demanding topic is robustness against uncertainties in a controlled system. READ MORE

3. Collagenous colitis : A study of epidemiology, etiology, clinical features and treatment
Abstract : Collagenous colitis (CC) is characterised clinically by chronic watery diarrhoea and histopathologically by an increased submucosal collagen layer. An epidemiologic study of CC during 1984 to 1993 showed a female:male ratio of 9:1. The median age at diagnosis was 64 (28-78) years. The prevalence was 15. READ MORE

4. Control, Models and Industrial Manipulators
Abstract : The two topics at the heart of this thesis are how to improve control of industrial manipulators and how to reason about the role of models in automatic control.On industrial manipulators, two case studies are presented. READ MORE

5. Low-rank optimization in system identification
Abstract : In this thesis, the use of low-rank approximations in connection with problems in system identification is explored. Firstly, the motivation of using low-rank approximations in system identification is presented and the framework for low-rank optimization is derived. READ MORE
