Research on fully-autonomous vehicles is a rising trend in the 21st century, since it is a promising area in which developments will be able to reduce work load of humans. As a specific research problem, studies on formation control theory have been done in the most recent years for fleets of autonomous vehicles in order to transform the way of transporting goods and individuals. This study focuses on a nonlinear virtual vehicle based controller, which is one of the formation control strategies in the liter ature. Since the existing work uses a kinematic vehicle model, his thesis extends the existing work to a dynamic bicycle car model, which is more realistic. Specifically, instead of assuming that the longitudinal and angular vehicle velocity can be directly applied as control inputs, the thesis designs controllers in order to track desired lon gitudinal and angular velocities provided by the formation controller. In a simulation study, the thesis compares the results of the kinematic and dynamic vehicle model, concluding that the formation control is satisfactory for the dynamic model if the designed controllers are tuned properly.

Trajectory planning and tracking for autonomous vehicles Çiçek, Haluk Levent; Schmidt, Klaus Verner; Department of Electrical and Electronics Engineering (2022-12-27) Finding appropriate paths is an essential issue for the development of autonomous vehicles and robots. Hereby, it has to be considered that autonomous vehicles cannot follow sharp corners, as they cannot turn on a single point. Therefore, it is important to compute smooth paths that have additional desirable properties such as minimum length and sufficient distance from obstacles. Furthermore, practical applications require the computation of such paths in real time. This thesis develops a general method...
Turbomachinery Noise Radiation through the Engine Exhaust (TURNEX) Özyörük, Yusuf(2005-1-01) Research is needed to develop innovative concepts and enabling technologies to reduce aeroengine noise at source. Turbomachinery noise radiating from the bypass and core nozzles is becoming the dominant noise source on modern aircraft, but, while recent EU research programmes have made significant progress in reducing both the generation of turbbmachinery noise and the radiation of noise from the intake, little work has been conducted on reducing the radiation of turbomachinery noise from exhaust nozzles. ...
Imagineering: a model approach for futuristic design thinking in urbanism Çalışkan, Olgu; Yavuz, Irmak (Thomas Telford Ltd., 2020-02-01) Under the prevailing condition of uncertainty that postulates the impossibility of predicting the long-term future of the contemporary urban societies, spatial planning and design seemingly require new methodologies for an effective future perspective on the human settlements. Used to rely on forecasting as an extrapolation technique projecting no further than 15-20 years ahead in practice, the profession largely falls insufficient to suggest a forward-thinking approach, today. To transcend such settled 'sh...
Feedback Motion Planning For a Dynamic Car Model via Random Sequential Composition Özcan, Melih; Ankaralı, Mustafa Mert (2019-01-01) Autonomous cars and car-like robots have gained huge popularity recently due to the recent advancements in technology and AI industry. Motion and path planning is one of the most fundamental problems for such systems. In the literature, kinematic models are widely adopted for planning and control for these type of robots due to their simplicity (control and analysis) and fewer computational requirements. Though, applicability of kinematic models are limited to very low speeds or some specific cases, which c...
Investment needs for climate change adaptation measures of electricity power plants in the EU Lise, Wietze; van der Laan, Jeroen (2015-10-01) Climate change is expected to have impacts on the power sector, leading to, among others, a need for adaptation measures in the sector in the near future. This paper analyses the need to adapt to climate change impacts for power generation technologies in Europe until 2100. Europe is broadly divided into four geographic climate zones, for which regional climate change impacts are quantified with the help of the ENSEMBLES RT2b data. The European future technology mix is based on two Eurelectric energy scenar...
