In this work, a finite element (FE) model of piezoelectric smart structures has formulated in ANSYS. The modal analysis of cantilever beam structure is carried out by using the Block Lanczos solver. The piezoelectric patches are located at the region of maximum strain for better control effect. The active vibration concept is demonstrated through simulation study in ANSYS for different shapes of actuators like rectangular, triangular s & rhombus. Closed loop simulation has also been done using strain feedback and displacement feedback. The tip displacements with and without the controller have been obtained and the performance of the proposed smart system is being evaluated for vibration control. From the responses of the each model with different shape of actuator patch, it has been observed that the control effect is better with rhombus patch.
