Vibration control of a smart piezo beam via gain scheduling H-infinity controller based on LPV model
TURAN, ABDULLAH; Şahin, Melin; ONAT, CEM (2021-01-01)
In this study, a gain scheduling H-infinity controller based on Linear Parameter Varying (LPV) model was designed and applied to suppress the first out of plane bending vibration of a variable parameter smart beam equipped...
Fibre Bragg grating sensor applications for structural health monitoring
Karatas, Cansu; Degerliyurt, Boray; Yaman, Yavuz; Şahin, Melin (Emerald, 2018-12-01)
Purpose
Extended Abstract: Dynamic Behavior of a Compliant Mechanism Driven by Stacked Piezoelectric Actuators
Koyuncu, A.; Şahin, Melin; Özgüven, Hasan Nevzat (2018-02-15)
Mechanical amplifiers are employed to enhance output displacement of piezoelectric actuators. Dynamic behavior of such an amplified piezoelectric actuator needs to be known accurately in order to verify its suitability for...
Active neuro-adaptive vibration suppression of a smart beam
Akin, Onur; Şahin, Melin (2017-12-01)
In this research, an active vibration suppression of a smart beam having piezoelectric sensor and actuators is investigated by designing separate controllers comprising a linear quadratic regulator and a neural network. Fi...
Enhancement of quality of modal test results of an unmanned aerial vehicle wing by implementing a multi-objective genetic algorithm optimization
Pedramasl, Nima; Şahin, Melin; ACAR, ERDEM (2017-12-01)
Due the fact that aircraft structures work in an environment with lots of dynamic forces, it is of vital importance to perform a dynamic analysis to understand dynamic characteristics of aircraft in that specific environme...
FIBER BRAGG GRATING SENSOR APPLICATIONS FOR STRUCTURAL HEALTH MONITORING
Karataş, Cansu; Değerliyurt, Boray; Yaman, Yavuz; Şahin, Melin (2017-09-30)
A well-known structural health monitoring method used to detect and locate damage in civil engineering structures is vibration-based damage identification. It typically monitors the civil structure over time to spot slow o...
EXPERIMENTAL STUDY ON ACTIVE VIBRATION CONTROL OF A PIEZO-BEAM STRUCTURE WITH FUZZY LOGIC CONTROLLER
Şenöz, Erdem Rahmi; Şahin, Melin (null; 2017-09-23)
In this study, it has been shown that active vibration control of the beam can be provided using the fuzzy logic controller. The test setup consists of a cantilever beam which illustrates a wing of airplane or a blade of h...
Structural and aerodynamic analyses of a hybrid trailing edge control surface of a fully morphing wing
Gürses, Ercan; Tunçöz, Ilhan Ozan; Yang, Yosheph; Arslan, Pinar; Kalkan, Ugur; Tıraş, Harun; Şahin, Melin; Özgen, Serkan; Yaman, Yavuz (2017-05-01)
In this article, the design and analysis of a hybrid trailing edge control surface of an unmanned aerial vehicle are presented. The structural design was performed to increase and decrease the camber of the control surface...
Structural Health Monitoring system of composite beams with surface bonded and embedded Fibre Bragg Grating sensors
Deǧerliyurt, Boray; Karataş, Cansu; Şahin, Melin; Yaman, Yavuz (2017-01-15)
Fibre Bragg Grating (FBG) sensors are frequently being used for Structural Health Monitoring (SHM) of aerospace structures. One of the most important advantages of using FBG sensors is that it is possible to embed them int...
Kiriş benzeri bir yapının farklı sayıda kural içeren bulanık mantık kontrolcüsü kullanarak ve pizeoelektrik uyarıcılar ile aktif titreşim kontrolünün performans kıyaslamasi
Şenöz, Erdem Rahmi; Şahin, Melin (null; 2016-09-28)
Bu çalışmada kirişin aktif titreşim kontrolünün bulanık mantık kontrolcüsü kullanarak sağlanması gösterilmiştir. Test düzeneği, bir ucu sabitlenmiş ve diğer ucu serbest olan alüminyum kirişin sabit ucuna yakın her iki yüze...
