This paper presents a simulation model for the active vibration control of a rectangular plate using piezoceramic elements of arbitrary shape. Experiments using multiple PZT patches were carried out to validate the model. An analysis was then undertaken to determine the dynamic effect of the piezoactuators. Numerical results showed that piezoactuators enhance the modal coupling of the structure under certain circumstances. Special attention should be paid to higher-order modes in both simulation and the development of active control strategies. Actuators of different shapes have been tested to show their influence on the dynamic behaviour of the structure. It was noted that actuators shapes affect the structure more in off-resonance regions than near resonance. This effect however remains weak as long as the actuators possess the same area and do not possess significantly different width to length dimensions.
