2. 16. Longitudinal Force Distribution and Road Vehicle Handling

   Author : Matthijs Klomp; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ehicle dynamics; quasi steady-state; drive force; combined grip; longitudinal force distribution; combined slip; vehicle handling; optimization;

   Abstract : The distribution of longitudinal forces has a large influence on vehicle handling characteristics such as the driver/vehicle interaction, road holding and yaw stability, in particular during combined traction/braking and cornering near the grip limit of the tires. In order to select and develop suitable driveline systems and associated active control that provide consistent driver/vehicle handling, maximum road holding and sufficient yaw stability margins, it is essential to understand the influence of a particular drive force distribution on these handling characteristics.

4. 17. On Drive Force Distribution and Road Vehicle Handling - A Study of Understeer and Lateral Grip

   Author : Matthijs Klomp; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drive force distribution; drive force; vehicle handling; lateral grip; understeer; acceleration; steady-state cornering; vehicle dynamics; combined slip;

   Abstract : Computer controlled vehicle sub-systems aimed to support drivers in various drivingsituations are rapidly increasing in number and sophistication. These systemshave evolved from anti-lock braking and traction control systems, to electronic stabilitycontrol. READ MORE

5. 18. On Motion Control and Machine Learning for Robotic Assembly

   Author : Martin Karlsson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Industrial robots typically require very structured and predictable working environments, and explicit programming, in order to perform well. Therefore, expensive and time-consuming engineering work is a major obstruction when mediating tasks to robots. READ MORE

6. 19. Cooperative and Interaction Control for Underwater Robotic Vehicles

   Author : Shahab Heshmati-Alamdari; Kostas J. Kyriakopoulos; National Technical University of Athens School of Mechanical Engineering Control Systems Lab; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Marine robotics; Robotics; Underwater Vehicle Manipulator Systems; Cooperative manipulations; Visual servoing; Nonlinear Model Predictive Control; Autonomous Underwater Vehicles; Industrial Information and Control Systems; Industriella informations- och styrsystem; Vehicle and Maritime Engineering; Farkostteknik;

   Abstract : In this dissertation we address the problem of robust control for underwater robotic vehicles under resource constraints and inspired by practical applications in the field of marine robotics. By the term “resource constraints” we refer to systems with constraints on communication, sensing and energy resources. READ MORE

7. 20. Flow Control and Shape Optimization of Intermediate Turbine Ducts for Turbofan Engines

   Author : Fredrik Wallin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; response surface methodology; intermediate turbine duct; vortex generators; turbine intermediate case; endwall contouring; turbine center frame; body-force model; shape optimization; mid-turbine frame; flow control;

   Abstract : Demands on improved efficiency, reduced emissions and lowered noise levels cause a strive towards high by-pass ratios of commercial turbofan engines. This results in an increased radial offset between the high- and low-pressure turbines. Thus the design of the intermediate turbine duct connecting the two turbines becomes more challenging. READ MORE
