Claim Text:
1. An active damping system comprising: an intermediate mass; a payload support having a first spring rate and adapted to couple between an isolated payload and the intermediate mass; an intermediate mass support having a second spring rate and adapted to couple between the intermediate mass and a base, wherein the second spring rate is greater than the first spring rate; a first active damping actuator having one end coupled to the intermediate mass and an opposite end adapted to couple to the base, wherein the first active damping actuator exhibits a stiffness that is less than a stiffness exhibited by the intermediate mass support; a first sensor configured to generate a first signal responsive to movement of the intermediate mass caused by dynamic forces; and a compensation module configured to couple to the first sensor and the first active damping actuator, wherein the compensation module is configured to receive the first signal and actuate the first active damping actuator to compensate for the dynamic forces acting on the intermediate mass.
