2. 1. Vehicle Dynamics Control for Rollover Prevention

   Author : Brad Schofield; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rollover Prevention; Control Allocation; Nonlinear Control; Convex Optimization; Vehicle Dynamics;

   Abstract : Vehicle rollover accidents are a particularly dangerous form of road accident. Existing vehicle dynamics controllers primarily deal with yaw stability, and are of limited use for dealing with problems of roll instability. READ MORE

4. 2. Safe Distributed Control Allocation for Articulated Heavy Vehicles

   Author : Umur Erdinc; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control allocation; Heavy vehicles; jackknifing; electric vehicles; trailer swing; stability;

   Abstract : The electrification of trucks is now followed by the electrification of trailers. Additionally, the maximum allowed length of vehicle combinations has been increased in many countries to enhance efficiency. READ MORE

5. 3. Topics in Modeling, Control, and Implementation in Automotive Systems

   Author : Magnus Gäfvert; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; Automation; robotics; robotteknik; Automatiska system; control engineering;

   Abstract : This thesis treats different aspects of automotive control-systems and consists of four papers covering different areas in this large field. The first paper presents a 9-degrees-of-freedom dynamic model of a tractor-semitrailer vehicle, aimed at simulation and evaluation of active chassis-systems for stability enhancements. READ MORE

6. 4. On Robust Steering Based Lateral Control of Longer and Heavier Commercial Vehicles

   Author : Maliheh Sadeghi Kati; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rearward Amplification; static output feedback; Commercial vehicles; LMI-based H ∞ synthesis; Dynamic Feed-forward; Robust Control;

   Abstract : Rapid growth in the transportation of goods has led to raised concerns about environmental effects, road freight traffic, and increased infrastructure usage. The increasing cost of fuel, and issues with congestions and gas emissions, make longer and heavier commercial vehicles (LHCVs) an attractive alter- native to conventional heavy vehicles. READ MORE

7. 5. Augmenting L1 Adaptive Control of Piecewise Constant Type to Aerial Vehicles

   Author : Anders Pettersson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : In aerial vehicle control design, the industrial baseline is to use robust control methods together with gain-scheduling to cover the full airspeed and altitude flight envelope. An adaptive controller could possibly add value by increasing performance while keeping robustness to deviation from nominal assumptions. READ MORE
