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 the first two flexural vibrational modes and the model correction technique was applied to compensate the possible error due to the higher order modes. The system model was also experimentally identified and both theoretical and experimental models were used together in order to determine the modal damping ratios of the smart beam. A spatial controller was designed for the suppression of the vibrations of the smart beam due to its first two flexural modes. The designed controller was then implemented to experimentally suppress the vibrations. This study also compared the effectiveness of a pointwise controller with the newly developed spatial one.

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...
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 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...
Spatial control of a smart beam Kircali, Omer Faruk; Yaman, Yavuz; Nalbantoglu, Volkan; Şahin, Melin; Karadal, Fatih Mutlu; Ulker, Fatma Demet (2008-08-01) This study presents the design and implementation of a spatial H(infinity) controller for the active vibration control of a smart beam. The smart beam was modeled by assumed-modes method that results in a model including large number of resonant modes. The order of the model was reduced by direct model truncation and the model correction technique was applied to compensate the effect of the contribution of the out of range modes to the dynamics of the system. Additionally, spatial identification of the beam...
