The system includes a packaging body, an active control module, and two passive control 5 modules. The packaging body primarily includes a side plate, a top plate, a bottom plate, two vertical partition plates, a cover plate, and a main force transfer plate. The active control module includes a mounting seat, a driver, a transmission, a rotary shaft, a rotary inertia disc, and a flange. The passive control module includes a suspension damper and a mass block. In the present invention, the rotary inertia disc of the system can be controlled to rotate 0 according to an actual moving condition of a structure, so that an appropriate force applied to a controlled bridge is provided to control vibration. In addition, in the system, the passive control modules are further arranged to cooperate with the active control module, forming a compound control system that can have a good control effect on both planar vibration of the bridge and flutter vibration of the bridge. 51/2 FIG.1 511 12 10 6 G 2 FIG. 2
