Patent ID: 6950727

Claim:
A vibration controller for active vibration insulators, the vibration controller comprising: an input signal generator for generating input signals comprising a control frequency and phase, the control frequency and phase based on cyclically pulsating signals emitted from a vibration generating source; an actuating waveform detector for detecting actuating waveforms of an electromagnetic actuator of active vibration insulators; waveform analyzing means for determining higher harmonic component datum information on the actuating waveforms by carrying out a waveform analysis on the actuating waveforms; a higher harmonic component signal generator for generating higher harmonic component signals of the actuating waveforms based on the higher harmonic component datum information; a higher harmonic component signal remover for removing the higher harmonic component signals from the input signals and outputting the resulting processed input signals; and an actuator for receiving the processed input signals, generating output signals based on the processed input signals and actuating the electromagnetic actuator in accordance with the output signals; whereby inhibiting the vibration generating source from vibrating by means of vibrating forces exerted by the electromagnetic actuator.
