Light flicker evaluation of electric arc furnaces based on novel signal processing algorithms Köse, Neslihan; Leblebicioğlu, Mehmet Kemal; Department of Electrical and Electronics Engineering (2009) In this research work, two new flickermeters are proposed to estimate the light flicker caused by electric arc furnaces (EAFs) where the system frequency deviates significantly. In these methods, analytical expressions of the instantaneous light flicker sensation are obtained beginning from a voltage waveform and these expressions are used to obtain a flicker estimation method based on the IEC (International Electrotechnical Commission) flickermeter. First method is a spectral decomposition based approach u...
Design, modelling and analysis of a novel implantable bone conduction hearing aid with a piezoelectric actuator Koyuncu, Anıl; Özgüven, Hasan Nevzat; Şahin, Melin; Department of Mechanical Engineering (2022-9-01) This thesis study proposes a novel bone conduction (BC) transducer design, which intends to overcome the drawbacks of conventional bone conduction hearing aids (BCHAs). A piezoelectric actuator design with a rhombus-type mechanical amplifier is chosen as a BC transducer in the first step, and a commercial amplified piezoelectric actuator (APA) is selected for trials. The dynamics of the mechanical amplifier and embedded stacked piezoelectric actuator are formulated separately based on linear analytical appr...
Full Envelope Nonlinear Controller Design for a Novel Electric VTOL(eVTOL) Air-taxi via INDI Approach Combined with CA Suiçmez, Emre Can; Kutay, Ali Türker; Department of Aerospace Engineering (2021-5) On-demand urban air mobility (UAM) has become very popular in recent years with the introduction of the electric vertical take-off and landing (eVTOL) aircraft concept. Thanks to the key advantages of electric propulsion (e.g., very low noise and zero carbon-emission), short/medium range eVTOL "air-taxi" concept emerged as a feasible solution considering the requirements of the on-demand UAM. With this motivation, flight control problems of a novel eVTOL air-taxi are discussed and a unified flight controlle...
Series active filter design, control, and implementation with a novel load voltage harmonic extraction method Şentürk, Osman Selçuk; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2007) Series Active Filters (SAF) are designed for harmonic isolation and load voltage regulation of single-phase and three-phase voltage harmonic source type nonlinear loads. The novel Absolute Value Method (AVM) for load voltage harmonic extraction is proposed and applied in the control algorithm of SAF. The SAF compensated systems are represented by simplified linear models such that SAF controller gains can be easily determined. Harmonic isolation and load voltage regulation performances of 2.5 kW single-phas...
Development of a novel surface damping treatment Eyyüpoğlu, Kemal Okan; Özgen, Gökhan Osman; Department of Mechanical Engineering (2016) Constrained layer surface damping treatments techniques have been widely used in commercial and defense products to increase the damping performance. It is known that the performance of surface damping treatments highly depend on the strain energy in the viscoelastic layer. As the strain energy in the viscoelastic layer increases, the energy dissipation magnifies which results in higher damping performance. A good way to magnify strain energy in viscoelastic layer is to increase the distance between the vis...
