Abstract
PURPOSE:To obtain a vibration-damping effect by regarding the information of a displacement sensor as information obtained in each degree of freedom, applying the rigidity of respectively different frequency characteristics to the information and distributing a control signal to respective driving means by a signal conversion means. CONSTITUTION:Frequency characteristics setting circuits by degree of freedom 341-346 set up frequency characteristics in each degree of freedom. Namely, the gain of rigidity in parallel 3 degrees of freedom is dropped from a comparatively low frequency on a frequency axis and the gain of rigidity in rotational 3 degrees freedom is secured up to a sufficiently high frequency. In a system, respective electromagnets 11... relate to plural degrees of freedom, signals 411-419 from the deformation sensors 21... include plural information of the degree of freedom in a rectangular system and the information of the deformation sensors 21... is converted into signals 431-436 in 6 deg. of freedom. Then, a high frequency component about the displacement of 3 deg. of freedom is removed and converted into driving signals 481-489 obtained in each electromagnet 11.... Consequently position and posture control can be attained without being influenced by the fine oscillation of the structure body.
