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...

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...

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...
"High precision CNC motion control"
Ay, Gökçe Mehmet; Dölen, Melik; Department of Mechanical Engineering (2004)
This thesis focuses on the design of an electrical drive system for the purpose of high precision motion control. A modern electrical drive is usually equipped with a current regulated voltage source along with powerful motion controller system utilizing one or more micro-controllers and/or digital signal processors (DSPs). That is, the motor drive control is mostly performed by a dedicated digital-motion controller system. Such a motor drive mostly interfaces with its host processor via various serial comm...
Evaluation of the robustness performanceof a fuzzy logic controller foractive vibration control of a piezo-beam via tip mass location variation
Şenöz, Erdem Rahmi.; Şahin, Melin; Department of Aerospace Engineering (2019)
This thesis presents a study in which a robust Fuzzy Logic Controller (FLC) is designed to suppress both free and the first resonance of a piezo-beam even if the position of the tip mass located on the beam varies. The cantilever aluminum piezo-beam involves the piezoelectric patches bonded on the surfaces to be used as a sensor and actuator for the vibration control and the displaceable tip mass attached to the free end of the piezo-beam and used to change the system parameters for checking the robustness ...
