摘要： Apparatus and methods to reduce unwanted motion in a payload of a precision instrument are described. The payload may be supported by an intermediate mass. A feedback signal based upon sensed motion of the intermediate mass may be applied to an intermediate-mass actuator arranged to drive the intermediate mass. Additionally, a feedforward signal may be applied to a payload actuator arranged to drive the payload and used to suppress unwanted motion of the payload. The feedforward signal may be derived from a source within the apparatus or external to the apparatus that would otherwise cause unwanted motion of the payload.

摘要： Apparatus and methods to reduce unwanted motion in precision instruments are described. An active vibration-isolation system may include a feedback loop that senses motion of an intermediate mass. In noisy environments, where the feedback loop would otherwise fail or provide inadequate isolation, feedforward control can be implemented to sense floor vibrations and reduce motion of the intermediate mass that would otherwise be induced by the floor vibrations. The feedforward control can reduce motion of the intermediate mass to a level that allows the feedback loop to operate satisfactorily.

摘要： An active damping system for use in connection with a vibration isolation system includes an intermediate mass between a base and an isolated payload. The intermediate mass is supported by at least one support element which also supports at least substantially all of the static forces of the isolated payload. An actuator dampens and isolates dynamic forces acting on the intermediate mass from the isolated payload. The active damping system also includes a payload support element and a passive damping element, both of which are coupled at one end to the payload platform and at an opposite end to the intermediate mass. A sensor is affixed to the intermediate mass to generate a feedback signal to a processor coupled to the actuator.
