In this study, H∞ controllers were designed and implemented on a smart beam. The smart beam consisted of an aluminum beam modeled in cantilevered configuration with eight surface bonded piezoelectric lead-zirconatetitanate (PZT) patches. The study used ANSYS® (v5.6) for the structural modeling of the smart beam. The system models were obtained through the system identification made on the experimental beam data. The H∞ active vibration controllers, which effectively suppressed the sinusoidally excited, in-vacuo forced vibrations of the smart beam due to its first two flexural modes, were then designed by using MATLAB® tool-boxes and implemented. During the experiments both the strain gauge and laser displacement sensor were used as vibration sensors. The theoretical and experimental characteristics were compared to verify the developed models. The effects of the higher beam vibrational modes and the damping were included in the system model as uncertainties. It was shown that H∞ active vibration controllers were very effective in suppressing the sinusoidally excited, in-vacuo forced vibrations of the smart beam. Some preliminary studies on the modelling and verification of a smart fin were also presented

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 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...
Application of spatial H-infinity control technique for active vibration control of a smart beam Kircali, Oemer Faruk; Yaman, Yavuz; Nalbantoglu, Volkan; Şahin, Melin; Karadal, Fatih Mutlu (2007-05-12) This study presents the design and implementation of a spatial H-infinity 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 t...

Optimal Control of a Smart Beam by Using a Luenberger Observer Onat, Cem; Şahin, Melin; Yaman, Yavuz (2013-06-26) This paper presents the design of an optimal vibration control mechanism, namely an LQR controller, with a Luenberger observer for a smart beam having surface bonded piezoelectric sensors and actuators. The approach intends to suppress the vibrations of the first flexural resonance of the smart beam. The smart beam studied was a cantilever aluminium beam with eight surface bonded Lead-Zirconate-Titanate (PZT) patches in bimorph configuration. The smart beam was excited at its first resonance frequency (appr...
