Classification: CPC F  G | IPC F  G

Claim 9:
10. A vibration-isolation system comprising:
a first isolation assembly to support a first portion of a payload or a payload support; the first isolation assembly including:
a first intermediate mass;
a first feedback motion sensor arranged to sense motion of the first intermediate mass;
a feedforward motion sensor to sense motion of a base;
a first actuator configured to drive the first intermediate mass relative to the base, wherein the base is configured to support at least the first actuator and the first intermediate mass; and
a first control system configured to process a first signal from the first feedback motion sensor and a feedforward signal from the feedforward motion sensor and output a first drive signal to drive the first actuator to reduce vibrational motion of the first intermediate mass, wherein without application of the feedforward signal from the feedforward motion sensor to the first control system, vibrational levels of the intermediate mass during operation of the vibration-isolation system saturate the feedback motion sensor.
