ABSTRACT:
A vibration controller includes an input signal generator for generating input signals 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, a waveform analyzer for determining higher harmonic component datum information by carrying out a waveform analysis, 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. Thus, it is possible to inhibit the vibration generating source from vibrating effectively and less expensively.
