The objective of this paper is to clarify the problems on realization of a vibration control mechanism and to examine a possibility of the vibration control by using piezoelectric film on the reflecting mirror which is used in the photocopier and printer. Those machines enable to print a picture and a character with a laser beam which is reflected by the mirror. A vibration problem of the reflecting mirror might be caused due to the increase of the printing speed. The sensor and actuator as a base of the smart structure are composed of a thin piezoelectric film to control the vibration of the reflecting mirror in this study. The piezoelectric film is a very frivolous high polymer material which is suitable to be installed on the structural surface. H_2 and H_∞ strategies are applied to design the control system for the vibration suppression of the reflecting mirror. The H_2 control system guarantees the optimal performance against a given external disturbance whereas the H_∞ control system permits the system design with robustness in frequency domain. The numerical analysis and the experiment demonstrate their performance for the vibration control of the reflecting mirror using the piezoelectric film.
