This paper presents an analysis of the active control the vibration of the structure. The purpose of this paper is to suggest one of the directives to design an active damper. The control hardware used is an active-mass-damper with DVFB (Direct Velocity FeedBack). This control law, feedbacks a local velocity to a controlled force, can suppress the structural vibration by only one sensor and one actuator. If a rigid mode does not exist and the sensor and the actuator are collocated, it never cause the spillover of the structure. The numerical model used includes the interaction between the structure and the damper. Its natures are investigated using characteristic valuses and frequency responses of the closed loop system. The effects of the vibration suppression are analyzed into the parameters of the damper. The results emphasis the importance of the viscous damping in the damper.
