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.

H_2 controller is designed with the reduced order model of smart pantograph structure which is obtained by finite element and modal analyses. The control force is applied by the piezoelectric film actuator and the feedback signals are detected by the accelerometer in the system. The vibration response is suppressed by modal control. The placement of the piezoelectric actuator and the H_2 control system are simultaneously optimized by using GA to achieve an enhanced vibration control performance. It has been verified by simulations that the enhanced performance for the vibration suppression can be achieved by the present method.
