Claim 11:
12. A vibration control system configured to vibrate a test object in a manner to match a reference vibration physical quantity waveform of a second dimension that differs from a first dimension of a drive waveform for vibrating the test object and of a response vibration physical quantity waveform, with which vibration of the test body is detected, the vibration control system comprising:
a vibration physical quantity detection sensor which detects a vibration physical quantity of the test object that is vibrated by a vibration generator operated on the basis of the drive waveform, so as to output the response vibration physical quantity waveform;
a processor, memory and instructions, the instructions when executed:
determine and output the drive waveform configured to drive the vibration generator on the basis of the reference vibration physical quantity waveform by using equalization characteristics as inverse characteristics of transfer characteristics of at least the vibration generator and the test object; and
modify the equalization characteristic as a reciprocal of a second dimension transfer function on the basis of the response vibration physical quantity waveform and the drive waveform, the second dimension transfer function being a ratio between a spectrum of the drive waveform and a spectrum of a second response vibration physical quantity waveform, which is acquired by converting the response vibration physical quantity waveform into that of the second dimension,
wherein the vibration physical quantity represents a vibration expressed as the first dimension and wherein the reference vibration physical quantity waveform of a second dimension represents a vibration expressed as a second, different dimension.
