Abstract

An acceleration sensor is attached to a rack housing. A FFT processing unit converts a signal output from the acceleration sensor, which is a time-domain signal, into a frequency-domain signal. An inverse input vibration component extraction unit extracts a signal, of which the frequency (f) falls within a predetermined range (fL ≤ f ≤ fH (fH > fL)) and of which the power density (p) falls within a predetermined range (pL ≤ ρ ≤ pH (ρH > pL)), from the frequency-domain signal obtained by the FFT processing unit. An IFFT processing unit converts the frequency-domain signal extracted by the inverse input vibration component extraction unit into a time-domain signal (estimated inverse input vibration). <img class="EMIRef" id="144778481-iaf01" />
