Abstract
An anti-vibration apparatus includes a table, an actuator system which applies a force to the table, a first system which applies to the actuator system a first signal for causing the actuator system to apply the force in proportion to a displacement of the table, and a second system which applies to the actuator system a second signal for causing the actuator system to apply the force based on an acceleration of the table. The first and second signals are generated by the first and second systems, respectively, so that a natural vibration mode of a system including the table and the actuator system is unchanged.
