Abstract

An active vibration isolation support system includes an electronic control unit which supplies a target electric current to an actuator to periodically drive the actuator in an expansion and contraction manner with a target vibration waveform. The controller sets the target electric current by synthesizing a driving primary electric current waveform corresponding to the target vibration waveform for the actuator with higher-order (driving secondary and/or tertiary) electric current waveforms which eliminate higher-order vibration components of the actuator corresponding to the driving primary electric current waveform. It is possible to alleviate a calculating load in the electronic control unit by ignoring the quaternary and still higher-order vibration components which less affect the target vibration waveform for the actuator.
