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. Fractional order controllers were known to provide better flexibility in adjusting the gain and phase characteristics than their integer-order counterparts. In the design of the controller, first, the fractional order differential effect was considered by using a fourth degree approach of continued fraction expansion (CFE) method. Then a filter was designed to characterize the dynamic properties of the smart beam in the first flexural mode. Finally, the controller was obtained by filtering the aforementioned differential effect. In order to evaluate the closed-loop frequency domain performances, the simulations were performed on various fractional orders of the differential effect and a controller was then selected for the experimental verifications. The obtained time domain responses have shown that the fractional order controller successfully suppressed the vibration levels of the first flexural mode of the smart beam.

Active Vibration Suppression of a Smart Beam by Using an LQG Control Algorithm
Onat, Cem; Şahin, Melin; Yaman, Yavuz (2011-06-22)
The aim of this study was to design and experimentally apply a Linear Quadratic Gaussian (LQG) controller for the active vibration suppression of a smart beam. The smart beam was a cantilever aluminum beam with eight symmetrically located surface-bonded PZT (Lead-Zirconate-Titanate) patches which were utilized both as sensor or actuator depending on their location. 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 s...
Active vibration suppression of a smart beam via self sensing piezoelectric actuator
Uğur, Arıdoğan; Şahin, Melin; Yaman, Yavuz; Volkan, Nalbantoğlu (null; 2009-08-17)
In this paper, an active vibration suppression of a smart beam using self-sensing piezoelectric actuator is presented. The smart beam is composed of a cantilever aluminium beam with four surface-bonded piezoelectric patches symmetrically located both side of the beam. Piezoelectric materials can transform mechanical deformation to electric signal and vice versa. This property of piezoelectric materials enables them to be used as an actuator and a sensor. In self-sensing actuator configuration, the piezoelec...
Active vibration control of a smart beam : a spatial approach
Kırcalı, Ömer Faruk; Yaman, Yavuz; Department of Aerospace Engineering (2006)
This study presented the design and implementation of a spatial Hinf controller to suppress the free and forced vibrations of a cantilevered smart beam. The smart beam consists of a passive aluminum beam with surface bonded PZT (Lead-Zirconate-Titanate) patches. In this study, the PZT patches were used as the actuators and a laser displacement sensor was used as the sensor. In the first part of the study, the modeling of the smart beam by the assumed-modes method was conducted. The model correction techniqu...
Active Vibration Suppression of a Smart Beam via PI D Control
Onat, Cem; Şahin, Melin; Yaman, Yavuz (2010-10-11)
: In this study, a PIλD µ controller was designed for the active vibration suppression of a smart beam equipped with PZT (Lead-Zirconate-Titanate) patches. The smart beam is a cantilever aluminium beam having eight symmetrically located surface-bonded piezoelectric patches. In this particular application, a group of PZT patches closed to the root of the beam was used as actuators and from the remaining ones a patch was nominated as a sensor. All the actuators were used in bimorph configuration. PIλD µ con...
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. Firstly, design of a smart beam which consists of a cantilever aluminum beam with surface bonded piezoelectric patches and a designed mechanism having a micro servomotor with a mass attached arm for obtaining variations in the frequency response function are presented. Secondly, the frequenc...
