An active vibration control technique is one of the important technical subjects for the large space structures (LSS). In the LSS, the one-board instruments need more strict directional precision as the sizes and flexibility of structures increase. With this background, a piezoelectric actuator Type-II for vibration control has been experimental developed, which has five multilayered piezo-electric devices. An attempt has been made to incorporate the actuator Type-II into active members of a truss structure, which is a 6-bay, 1.8m-high truss, and to control its vibration. This paper presents an outline of the piezo-electric actuator Type-II and some experimental results which show the vibration control capabilities of the actuator Type-II.
