PURPOSE:To control any vibration in a space structure so quickly by installing a control means which controls a coupling member positioner so as to move a coupling member in a direction of checking vibrations in a coupled structural element by an output signal of a vibration detecting means. CONSTITUTION:At the active side, there are provided with a damping sensor 32 detecting a strain and a displacement sensor 46, while each structural element at the passive side, there is provided with each rocking sensor 57. Each output out of these sensors is read in order by a multipoint measuring high-speed A/D scanner 55, and a rocking mode at the point of time is analyzed by a high-speed multidimensional rocking analyzer 58, and for damping, a moving position at the passive side is given to a 4-axis controller 59 as a control signal of four axes of X-Y-Z-theta. Then, a signal is given to each controller of each electrically direct driving motor 17 for eccentric rotors 10, 13, a X-axis rotor 15 and a Z-axis rectilinear rotor 23 of a coupling member positioner 5 from this controller 59, controlling output of each motor 17, and a coupled shaft 1 is displaced, whereby the structural element at the passive side is moved in the damping direction, preventing vibrations from occurring. |
