1. Relay Feedback and Multivariable Control
Abstract : This doctoral thesis treats three issues in control engineering related to relay feedback and multivariable control systems. Linear systems with relay feedback is the first topic. Such systems are shown to exhibit several interesting behaviors. READ MORE

2. 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

3. Extremum Seeking Control : Stability, Accuracy, and Applications
Abstract : In many applications, there is a variable that indicates the overall performance and that must be maximized, such as the output of a hydro power turbine or a mineral processing plant, or that must be minimized, such as CO2 emissions or the consumption of resources. Extremization of this variable (maximization or minimization) through adjusting the influencing manipulated variables is occasionally required without prior knowledge of the optimal values of the manipulated variables or of the optimized variable.

4. Model Predictive Control in Flight Control Design : Stability and Reference Tracking
Abstract : Aircraft are dynamic systems that naturally contain a variety of constraints and nonlinearities such as, e.g., maximum permissible load factor, angle of attack and control surface deflections. READ MORE

5. Essays on Mergers and Acquisitions and Event Studies
Abstract : This dissertation consists of three studies on the anticipation of mergers and acquisitions (M&As) and its impact on takeover event studies. Article I investigates whether the market can anticipate both takeovers and their payment forms prior to their announcement dates. READ MORE
