804 - Modal analysis and control of adaptive structures with shear piezoelectric actuators
Al-Ajmi M., Tawfik M.
Abstract
The shear actuated control of structures has occupied a considerable portion of the literature in the previous years. Shear controlled mechanisms has proven effective in active vibration damping with advantages that has been reported repeatedly. In this paper, we present a model for the control of the sandwich beam vibration using the assumed modes method. A velocity feedback control algorithm is used. The results have proven the accuracy of the model as well as the effectiveness of the control mechanism. Also, it was shown that the control was more effective when based on the second mode vibration.
