The present work demonstrates the successful application of a simple active vibration control procedure based on structural dynamics. Based on theories of mathematical and structural dynamics, the appropriate locations of sensor and actuator of smart structure were predicted. Also, the optimum value of actuator force which controls the structural vibrations is quickly formulated so that the first damping coordinates becomes critical. The validity and efficiency of the proposed method have been investigated by active vibration suppression of some classic structural models. The results showed the ability of suggested active control processes in suppression of the unwanted structural vibrations.
