1. Relay Feedback and Multivariable Control
University dissertation from Department of Automatic Control, Lund Institute of Technology (LTH)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
University dissertation from Linköping : Linköping University Electronic PressAbstract : 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
University dissertation from Luleå tekniska universitetAbstract : 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
University dissertation from Linköping : Linköping University Electronic PressAbstract : 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. Global stability and feedback control of boundary layer flows
University dissertation from Stockholm : KTHAbstract : In this thesis the stability of generic boundary layer flows is studied from a global viewpoint using optimization methods. Global eigenmodes of the incompressible linearized Navier-Stokes equations are computed using the Krylov subspace Arnoldi method. READ MORE
