2. 16. On design methods for mechatronics : servo motor and gearhead

   Author : Fredrik Roos; Jan Wikander; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; mechatronics design methodology; servo systems; electric motors; gears; auxiliary systems; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

   Abstract : The number of electric powered sub-systems in road-vehicles is increasing fast. This development is primarily driven by the new and improved functionality that can be implemented with electro-mechanical sub-systems, but it is also necessary for the transition to electric and hybrid-electric drive trains.

4. 17. Tools for Control System Design : Stratification of Matrix Pairs and Periodic Riccati Differential Equation Solvers

   Author : Stefan Johansson; Bo Kågström; Erik Elmroth; Paul Van Dooren; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; control system design; stratification; controllability; observability; matrix pair; canonical forms; linear quadratic regulator; periodic systems; periodic Riccati differential equation; Computer science; Datavetenskap; Numerical Analysis; numerisk analys;

   Abstract : Modern control theory is today an interdisciplinary area of research. Just as much as this can be problematic, it also provides a rich research environment where practice and theory meet. This Thesis is conducted in the borderline between computing science (numerical analysis) and applied control theory. READ MORE

5. 18. Linear wave energy converter : Study of electromagnetic design

   Author : Erik Lejerskog; Mats Leijon; Giuseppe Passoni; Uppsala universitet; []
   Keywords : Wave energy; permanent magnets; linear generator; closed stator slots; offshore experiments;

   Abstract : The thesis presents results from synchronous linear wave energy converters developed at Uppsala University. A study is done on closed stator slots and a study presenting offshore data focusing on the power absorption from a wave energy converter (WEC). READ MORE

6. 19. Contributions to motion planning and orbital stabilization : case studies: Furuta pendulum swing up, inertia wheel oscillations and biped robot walking

   Author : Pedro Xavier Miranda La Hera; Anton Shiriaev; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Under-actuated Systems; Orbital Exponential Stability; Motion Planning; Virtual Constraints; Walking robots; Automatic control; Reglerteknik;

   Abstract : Generating and stabilizing periodic motions in nonlinear systems is a challenging task. In the control system community this topic is also known as limit cycle control. In recent years a framework known as Virtual Holonomic Constraints (VHC) has been developed as one of the solutions to this problem. READ MORE

7. 20. On Derailment-Worthiness in Rail Vehicle Design : Analysis of vehicle features influencing derailment processes and consequences

   Author : Dan Brabie; Evert Andersson; Roderick A Smith; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; derailment; bogie design; wheel-sleeper impact; simulation; deviation; vehicle inter-connection; guidance mechanism; substitute guidance; articulated train; railway safety; Vehicle engineering; Farkostteknik;

   Abstract : This thesis aims at systematically studying the possibilities of minimizing devastating consequences of high-speed rail vehicle derailments by appropriate measures and features in the train design including the running gear. Firstly, an empirical database is established containing as much relevant information as possible of past incidents and accidents that have occurred at substantial running speeds due to mechanical failure close to the interface between the running gear and the track.
