The placement of the piezoelectric actuator and the H₂ control system in a smart structure are simultaneously optimized by genetic algorithm to achieve an enhanced vibration control performance. Efficient optimization algorithm based on a two-step procedure is employed in the simultaneous optimization, in which the optimal piezoelectric placement and state feedback controller are obtained by genetic algorithm at the 1st-step and then the dynamic compensator for the output feedback is reconstructurcted at the 2nd-step of the optimization. It is verified by some applications with a plate structure and a magnetic disk drive that an enhanced performacne for the vibration suppression can be achieved by the presented optimal design.
