Vibration suppression is very important to boost the performance of advanced mechatronics devices. It has been expected that technology of smart structure will contribute to the development of small and light-weight mechatronics devices with the required performance. The smart structure is composed of the piezoelectric sensor and actuator in order to reduce the structural vibration. The placement of the piezoelectric actuator and H_2 control system are simultaneously optimized based on genetic algorithm to improve the effect on the vibration suppression. It has been verified by applications with an L-shaped beam and a plate-type smart structures that an enhanced performance for the vibration suppression can be achieved by the proposed optimal design method.
