  • Waveform control device for vibrating tables and method thereof
    Patent number: 6414452
    Abstract: A waveform control unit of a vibrating table comprises: an off-line compensation wave generator which generates an off-line compensation wave on the basis of the inverse characteristic of the vibrating table determined before performing an excitation and a target wave; and an on-line compensation wave generator which generates an on-line compensation wave on the basis of the inverse characteristic of the vibrating table during the excitation determined on the basis of the data of an excitation wave and a reproduced wave during the excitation and the target wave, and it switches the excitation wave to a mixed compensation wave based on the on-line compensation wave from the off-line compensation wave, during the excitation.
