Abstract:
Disclosed is a stage system and metrology apparatus comprising at least one such stage system. The stage system comprises a stage carrier for holding an object and a stage carrier positioning actuator for displacing the stage carrier. The stage system also comprises a balance mass to counteract a displacement of the stage carrier, and a balance mass positioning actuator for displacing the balance mass. A cable arrangement is connected to the stage carrier for the supply of at least power to said stage carrier. The stage system is operable to apply a compensatory feed-forward force to the balance mass which compensates for a cable arrangement force exerted by the cable arrangement.

Claim (Index 18):
The stage system of  claim 17 , being operable to:\n model the cable arrangement to obtain an estimate of the cable arrangement force from the stage carrier position, and use the estimate of the cable arrangement force to determine the compensatory feed-forward force.
