Shape memory alloys (SMAs) are active metallic "smart" materials used as actuators and sensors in high technology smart systems [1]. The term shape memory refers to ability of certain materials to "remember" a shape, even after rather severe deformations: once deformed at low temperatures, these materials will stay deformed until heated, whereupon they will return to their original, pre-deformed "learned" shape [2]. This property can be used to generate motion and/or force in electromechanical devices and micro-machines. However, the accuracy of SMA actuators is severely limited by their highly nonlinear stimulus-response characteristics. In this work, modeling, simulation, and experimental efforts to precisely control the position of a Ni-Ti based shape memory alloy wire is presented. In this content three separate control strategies are tried and very good positioning accuracies are obtained.

Finite strain modeling of coupled thermo-mechanical behavior of polycrystalline ni-ti shape memory alloys
Rezazadeh, Vahid; Dal, Hüsnü; Aslan, Özgür; Department of Mechanical Engineering (2017)
Shape memory alloys (SMAs) hold a significant importance in different areas such as aeronautics,adaptive structures,oil/gas down-hole, and high-temperature applications of automobile industry. Nowadays,researchers have already become well-aware of these applications and attempted to discover all the primary features of this specific smart material. Meanwhile, there is a growing effort to produce mathematical models in order to imitate the related behavior in a precise manner. Due to the crucial need to have a fi...
Giriş Kısıtlı Ters Sarkaç Mekanizmasının Optimal Kontrolü
SOVUKLUK, Sait; Ankaralı, Mustafa Mert (2021-08-01)
Rapid developments in today's actuator and sensor technologies have pioneered the development of platforms containing very different actuator and sensor combinations. In order to utilize the potentials of the platforms in the best way, it has become a necessity to develop new methods in control systems and new control methods have begun to be gathered under the name of modern control. The optimal control, which is one of the subtitles of modern control, has started to be used widely today with the increase ...
A VERSATILE MICROCOMPUTER INTERFACE AND PERIPHERAL DEVICES - AN APPLICATION IN DEUTERIUM LAMP BACKGROUND CORRECTION GRAPHITE-FURNACE ATOMIC-ABSORPTION SPECTROMETRY
GOKMEN, A; YALCIN, S (1992-01-01)
A versatile interface card for Apple IIe computer and various peripheral devices are designed to control instruments which generates transient signals like in graphite furnace atomic spectrometer. The interface card consists of a multiplexed analog-to-digital converter, a digital-to-analog converter, and a timer/counter chip. The timer/counter chip with 16 built-in registers can be programmed in many modes which provides a time base for real-time measurements. A stepper motor runs under the control of ti...
Enhancement of the reliability of MEMS shock sensors by adopting a dual-mass model
Fathalilou, Mohammad; Soltani, Kamran; Rezazadeh, Ghader; Ciğeroğlu, Ender (Elsevier BV, 2020-03-01)
MEMS shock sensors are widely used with applications ranging from aircraft to electrical measurement systems. They are designed to operate at the shocks above a predefined threshold level. The conventional single-mass switches may lose their reliability at shock levels smaller than the threshold, if experience smaller unwanted pulse duration. This paper has proposed a dual-mass switch with auxiliary mass-spring attached to the main system which increases the reliability of the sensor against the unwanted pu...
Strengthening of L-shaped composite laminates using carbon nanotube reinforcement and thin ply non-crimp fabrics
Arca, Miray Aydan; Çöker, Demirkan; Papila, Melih; Department of Aerospace Engineering (2014)
The advances in manufacturing technologies have increased the use of composite materials in complex shapes such as curved beams. However, use of composites in complex geometries creates a weakness at the curvature and causes delamination failure. Major objective is to provide solution for this problem without degrading properties or increasing the weight of the structure. In this study, the effect of CNTs in the resin and the use of non-crimp fabric on the fracture toughness and curved beam strength of lami...
