This study presents an active vibration control technique applied to a smart beam. The smart beam consists of an aluminum beam modeled in cantilevered configuration with surface bonded piezoelectric (PZT) patches. The study uses ANSYS (v5.6) package program. The study first investigates the effects of element selection in finite element modeling. The effects of the piezoelectric patches on the resonance frequencies of the smart structure are also shown. The developed finite element model is reduced to a state-space form suitable for a controller design. The work then, by using this reduced model, presents the design of an active vibration controller which effectively suppresses the vibrations of the smart beam due to its first two flexural modes. The vibration suppression is achieved by the application of H∞ controllers. The effectiveness of the technique in the modeling of the uncertainties is also presented

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 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...

This study presents a µ-synthesis active vibration control technique applied to the sinusoidally forced vibrations of a smart fin. The smart fin consists of a cantilever aluminum passive plate-like structure with surface bonded piezoelectric (PZT, LeadZirconate-Titanate) patches. The study presents the design of controllers via µsynthesis, which effectively suppress the vibrations of the smart fin due to its first flexural and first torsional modes. Two different experimental set-ups are used in the study. ...

This study presents the design and implementation of a spatial H∞ controller for the active vibration control of a cantilevered smart beam. The smart beam consists of a passive aluminum beam (507x51x2mm) and eight symmetrically surface bonded SensorTech BM500 type PZT (Lead-Zirconate-Titanate) patches (25x20x0.5mm). PZT patches are used as actuators and a laser displacement sensor is used as sensor. The smart beam was analytically modelled by using the assumed-modes method. The model only included the first...
