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.
