摘要: A lithographic apparatus including: an object having compliant dynamics; a plurality of actuators configured to act on the driven object, wherein are over- determined in actuator degree freedom; control system including transformation matrix generate controller output signals for each response sequence setpoints, is such that do not excite dynamics at least one freedom.
