This paper presents a vibration suppression control patch was used as an actuator element, while the other was used as a sensor. The controller design was designed via the balance realization reduction method to elect the reduced order model that is most controllable and observable. sliding mode observer was designed to estimate six states from the reduced order model but three states are only used in the control law. Estimating a number of states larger than that used is in order to increase the estimation accuracy. Moreover, the state estimation error is proved bounded states with the sliding mode observer, to elements. The control spillover problem was avoided, by deriving an avoidance stability for the proposed vibration control design. attenuation ability of the proposed optimal control. For 15 mm initial tip able to reduce the tip displacement to about 0.1 experimental results showed a good performance of the proposed LQR control law and the sliding mode observer well a good agreement with theoretical results.

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 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 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...
Active neuro-adaptive control of a smart beam having uncertainties in structural dynamics
Akın, Onur; Şahin, Melin; Department of Aerospace Engineering (2015)
In this thesis, 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. At first, 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 frequency...
Giriş Kısıtlı Ters Sarkaç Mekanizmasının Optimal Kontrolü
SOVUKLUK, Sait; Ankaralı, Mustafa Mert (2021-08-01)
Rapid developments in today's actuator and sensor technologies have pioneered the development of platforms containing very different actuator and sensor combinations. In order to utilize the potentials of the platforms in the best way, it has become a necessity to develop new methods in control systems and new control methods have begun to be gathered under the name of modern control. The optimal control, which is one of the subtitles of modern control, has started to be used widely today with the increase ...
