: 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 controllers were known to provide better flexibility in adjusting the gain and phase characteristics than conventional integer-order PID controllers. The parameters of PIλD µ controllers are composed of the proportionality constant, integral constant, derivative constant, derivative order and integral order; hence its design is inevitably more complicated than that of a PID controller. First, the optimization problem of the regulator controller’s required parameters was established by using the transfer function of the smart beam. That transfer function was experimentally obtained by means of using aforementioned group of sensor/actuator piezoelectric patches. The PIλD µ controller was then considered by using a fourth degree approach of continued fraction expansion (CFE) method. Following this, the optimization problem of finding the PIλD µ controller’s parameters was solved by using both the MATLAB Optimization Toolbox and an optimization model, which has been developed in house by using MATLAB Simulink package program. The simulation results obtained in time domain demonstrated that the designed controller successfully suppressed the vibration levels of the smart beam for the first two flexural modes.

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 Hinf Active Vibration Control Strategy in Smart Structures Yaman, Yavuz; Volkan, Nalbantoğlu; Tarkan, Çalışkan; Eswar, Prasad; Davıd, Waechter; Bın, Yan (2003-07-01) 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-v...

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 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...
