Evaluation of the robustness performanceof a fuzzy logic controller foractive vibration control of a piezo-beam via tip mass location variation
Şenöz, Erdem Rahmi.; Şahin, Melin; Department of Aerospace Engineering (2019)
This thesis presents a study in which a robust Fuzzy Logic Controller (FLC) is designed to suppress both free and the first resonance of a piezo-beam even if the position of the tip mass located on the beam varies. The cantilever aluminum piezo-beam involves the piezoelectric patches bonded on the surfaces to be used as a sensor and actuator for the vibration control and the displaceable tip mass attached to the free end of the piezo-beam and used to change the system parameters for checking the robustness ...
Development of a high fidelity finite element model of a wind turbine blade via modal testing
Amer, Chadi; Şahin, Melin; Department of Aerospace Engineering (2015)
The design of an optimised horizontal axis 5-meter-long wind turbine rotor blade, is a research and development project, in order to fulfil the requirements of high efficiency torque-from-wind production. For this purpose, a research study is presented here, by investigating the structural characteristics of a composite wind turbine blade via finite element modelling and experimental modal analysis. At first, modal tests are performed by using various sensor-actuator pair combinations. After that the geomet...
Performance evaluation of an underwater acoustic sensor network communication protocol
Acar, Derya; Bilgen, Semih; Department of Electrical and Electronics Engineering (2014)
Underwater acoustic sensor networks constitute a popular research issue, regarding which researchers have especially focused on energy efficiency problem. Methods to minimize energy consumption have been investigated in terms of network layers, especially data link and routing layer. However, RPUASN (Remotely Powered Underwater Acoustic Sensor Networks), which is a recent proposal, solves this problem by including acoustic energy sources and sensor nodes which can harvest the emitted energy in the environme...
Structural optimization of a triner aircraft wing by using genetic algorithm
Çakır, Mustafa Kağan; Söylemez, Eres; Department of Mechanical Engineering (2008)
In this study, a design procedure incorporating a genetic algorithm (GA) is developed for optimization of the wing structure of a two seated trainer aircraft with single turboprop engine. The objective function considered is the total weight of the structure. The objective function is minimized subjected to certain strength requirements. In order to evaluate the design constraints and model the wing structure, finite element analysis is performed by using a conventional finite element solver (i.e. MSC/NASTR...
