To solve a problem in conventionally known excitation control technology wherein, since a highly reliable acceleration response cannot be obtained throughout all frequency ranges, it is difficult to determine an accurate transfer function, and, as a result, even if a drive signal of an actuator is repeatedly corrected by iteration processing, a proper drive signal cannot be generated always.

By using the actuator 12 driving a shaking table 10 in response to a drive signal, a displacement gauge 14 outputting a displacement signal by detecting a displacement amount of the shaking table 10, an accelerometer 18 outputting an acceleration signal by detecting acceleration in a predetermined position of a sample 16 placed on the shaking table 10, and a transfer function T(ω) determined on the basis of both of the displacement signal and the acceleration signal, the transfer function accurate throughout all frequency ranges can be identified. As a result, by repeatedly correcting an initial drive signal, a target acceleration signal can be obtained.
