A Magnetostrictive Composite-Fiber Bragg Grating Sensor
This paper presents a light and compact optical fiber Bragg Grating sensor for DC and AC magnetic field measurements. The fiber is coated by a thick layer of a magnetostrictive composite consisting of particles of Terfenol-D dispersed in a polymeric matrix. Among the different compositions for the coating that were tested, the best magnetostrictive response was obtained using an epoxy resin as ...
متن کاملControl Study of Precision Giant Magnetostrictive Actuator Based on Active Disturbance Rejection Control Technology
Introduce the structure and working principle of precision giant magnetostrictive actuator and establish the actuator system object transfer function model so as to design a suitable active disturbance rejection controller (ADRC). According to the model analysis, regard the actuator system as a first-order inertia object with dead time to construct second-order ADRC, use MATLAB for parameter tu...
متن کاملFull-field infrared phase sensitive thermography for microstructural investigation of giant magnetostrictive materials
Background: Giant magnetostrictive materials are increasingly proposed for smart material applications such as in sensors, actuators, and energy harvesting applications. However, reviewing the literature on this topic, the reader observes a large amount of variability in the reported properties that are typically generated from overall strain or point-value strain measurements obtained with str...
متن کاملVibration suppression analysis for laminated composite beams embedded actuating magnetostrictive layers
This paper presents the analysis of vibration control of a laminated composite beam that including magnetostrictive layers. The formulation of problem is presented based on the shear deformation beam theory. For vibration suppression, the velocity feedback control with constant gain distributed is considered. Navier's method is applied to analyze the solution of vibration suppression of laminat...
