Motion platforms are widely employed in military systems for the purpose of controlling payloads like optical sensors, antennas, guns etc. One of the most critical components of these platforms is the motion control sub-system which is responsible for controlling the speed of the platform. In this thesis, the components of the speed control are investigated in detail and finally a novel control architecture was proposed in order to improve the transient performance of the speed control without any adverse effect on its robustness. This architecture is a form of indirect adaptive control using Self-Recurrent Wavelet Neural Networks (SRWNNs). The architecture is enhanced by a novel parameter update method in order to guarantee fast convergence, and an additional algorithm for structural evolution. The performance of the proposed architecture has been shown with simulations and verified with experiments. Moreover, its performance is compared with several robust RST-based control designs.

Immune system based distributed node and rate selection in wireless sensor networks
Atakan, Baris; Akan, Ozguer B. (2006-12-13)
Wireless sensor networks (WSNs) are event-based systems that rely on the collective effort of dense deployed sensor nodes. Due to the dense deployment, since sensor observations are spatially correlated with respect to spatial location of sensor nodes, it may not be necessary for every sensor node to transmit its data. Therefore, due to the resource constraints of sensor nodes it is needed to select the minimum number of sensor nodes to transmit the data to the sink. Furthermore, to achieve the application-...
Comparative design of millimeter wave RF-MEMS phase shifters
Kobal, Enis; Demir, Şimşek; Department of Electrical and Electronics Engineering (2016)
Phase shifters are widely used for electronic beam steering for various antenna applications. This thesis presents design and comparison of 3 di erent 3-bit transmission type phase shifters, which are switch-line, Distributed MEMS Transmission Line (DMTL) and triple stub phase shifters, realized with capacitive contact Radio Frequency (RF) Micro-Electro-Mechanical Systems (MEMS) switches for Ka-Band applications. For the design of switch-line phase shifter reducing the sensitivity of the electrical performa...
High operating temperature mid-wave infrared HgCdTe photodiode design
Yurtseven, Eray; Kocaman, Serdar; Department of Electrical and Electronics Engineering (2019)
Infrared focal plane arrays are critical components in many of the military and civilian applications for advanced imaging systems. HgCdTe is one of the most widely used infrared detector material. An important issue with this material for thermal imaging system is the operating temperature as it determines cryocooler crucial characteristics, namely power comsumption and device lifetime. Therefore, there is an effort towards to operate at higher temperatures, but performance characteristics need to be caref...
Modeling and simulation of a small-sized Tiltrotor UAV
Çakıcı, Ferit; Leblebicioğlu, Mehmet Kemal (2012-10-01)
Unmanned aerial vehicles (UAVs) are remotely piloted or self-piloted aircrafts that can carry cameras, sensors, communication equipment and other payloads. Tiltrotor UAVs provide a unique platform that fulfills the needs for ever-changing mission requirements, by combining the desired features of hovering like a helicopter and reaching high forward speeds like an airplane, which might be a force multiplier in the battlefield. In this paper, the conceptual design and aerodynamical model of a realizable small...
SWIR objective design using seidel aberration theory
Aslan, Serhat Hasan; Yerli, Sinan Kaan; Keskin, Onur; Department of Physics (2016)
Optical systems are used for increasing the situational awareness and Intelligence, Surveillance and Reconnaissance (ISR) capabilities for military purposes. MWIR (Midwave infrared) and LWIR (Long wave infrared) waveband informations are the first two wavebands information in the atmospheric transmission window that are harnessed in military night vision optical systems. Another candidate of these operable wavebands is the SWIR (Shortwave infrared). Shortwave infrared (SWIR) imaging is an extension of Near ...
