Power Amplifiers (PA) are widely used in mobile communication systems, yet power amplifiers have a non-linear region which is the major problem in all communication and radar systems. Moreover, PAs show a low power efficiency when operating in their linear region and are highly non-linear when operating in their high-efficiency region. To overcome such issues, there are different methods to linearize PAs and other methods to enhance their power efficiency. These linearization methods are built to meet a cer...
Intelligent methods for dynamic analysis and navigation of autonomous land vehicles
Kaygısız, Hüseyin Burak; Erkmen, Aydan Müşerref; Department of Electrical and Electronics Engineering (2004)
Autonomous land vehicles (ALVs) have received considerable attention after their introduction into military and commercial applications. ALVs still stand as a challenging research topic. One of the main problems arising in ALV operations is the navigation accuracy while the other is the dynamic effects of road irregularities which may prevent the vehicle and its cargo to function properly. In this thesis, we propose intelligent solutions to these two basic problems of ALV. First, an intelligent method is pr...

Investigation of modular multilevel converter control methods
Ertürk, Feyzullah; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2015)
The thesis focuses on the analysis and control of modular multilevel converter (MMC). The control structures used in the control of MMC are presented. Outer control loops of the converter such as output current, DC-link voltage, and power controls as well as inner control structures unique to the converter such as circulating current control and sorting algorithm based submodule voltage balancing are investigated. In addition, switching methods proposed for MMC are also described. These control and switchin...
Tool support for distributed agile software development
Usta, Ahsen Serkan; Bilgen, Semih; Department of Electrical and Electronics Engineering (2006)
Agile Software Development has gained popularity with their people centric view and their common practices for developing software in today’s volatile business world where change on requirements is unavoidable. However; the efficiency of the project depends on the communication and the collaboration of the team, which are supported by the co-location of the team. But in some cases colocation of the team cannot be realized, thus agile processes should also support distributed teams. This point was observed b...
