An experimental performance evaluation for the suppression of vibrations of the second mode of a smart beam

In this study the fractional controllers, which were realized by the different degrees of the Continued Fractional Expansion (CFE) method, were experimentally evaluated for the suppression of the vibrations of the second mode of a smart beam. The smart beam is equipped with PZT patches and these patches were used both as actuator and/or sensor. The control strategy was based on the fractional derivation of the measurement signal which was the displacement values and filtering that signal by using a filter which was designed to characterise the dynamic properties of the second mode of the smart beam. The experimental results showed that when the controller was realized with a higher fractional derivation degree, better vibration suppression was provided for the second mode.


Active Vibration Suppression of a Smart Beam by Using a Fractional Order Control
Onat, Cem; Şahin, Melin; Yaman, Yavuz (2011-06-22)
In this study, a fractional order controller was designed and experimentally applied for the active vibration suppression of a smart beam. The smart beam was a cantilever aluminium beam equipped with eight symmetrically located surface-bonded PZT (Lead-Zirconate-Titanate) patches which were used both as sensor and actuator. For this particular application, a group of PZT patches closed to the root of the beam was used as actuators in the bimorph configuration and a single patch was nominated as a sensor. Fr...

In this study, the structural, electronic, mechanical, lattice dynamical and thermodynamic characteristics of ( 1, 2 and 3) phase compounds were investigated using the first principle calculations. These ternary nitride compounds were found to be stable and synthesisable, and the results on the stability nature of them were also evaluated for the possible and phases. -was found to be the most stable one among these new class of layered phases for which limited works are available in the literature. The band...
A study on the discretization of fractional Brownian motion
Coşkun, Buket; Vardar Acar, Ceren; Demirtaş, Hakan (2020-12-01)
In this study, we first discretize the fractional Brownian motion in time and observe multivariate Gaussian random variables (mGrv) to have a fractional Gaussian noise (fGn). Afterwards, we have discretized this discrete time process in space using a discretization proportion p and observe a random walk. We carry out this simulation study to foresee whether the correlated random walk using certain discretization parameters p behave similar to fBm. Based on this simulation study, we conclude on two important...

In this study, a fabrication method utilizing parylene bonding for gravimetric resonant based mass sensors is presented. First, parylene bonding was experimentally tested and compared with the literature. Average shear strength was measured as 16.3 MPa (sigma=3MPa). Then, resonators located on top of a microchannel for real-time detection were fabricated using the presented method. Simulations and experiments verify proper operation of the fabricated resonators, and the applicability of the method for fabri...
Principal-component analysis of two-particle azimuthal correlations in PbPb and pPb collisions at CMS
Sirunyan, A. M.; et. al. (2017-12-01)
For the first time a principle-component analysis is used to separate out different orthogonal modes of the two-particle correlation matrix from heavy ion collisions. The analysis uses data from root s(NN) = 2.76 TeV PbPb and root s(NN) = 5.02 TeV pPb collisions collected by the CMS experiment at the CERN Large Hadron Collider. Two-particle azimuthal correlations have been extensively used to study hydrodynamic flow in heavy ion collisions. Recently it was shown that the expected factorization of two-partic...
