Lithographic apparatus and device manufacturing method

A lithographic apparatus includes an illumination system configured to condition a radiation beam, and a support structure constructed to support a patterning device. The patterning device imparts the radiation beam with a pattern in its cross-section to form a patterned radiation beam. A substrate table is constructed to hold a substrate, and a projection system projects the patterned radiation beam onto a target portion of the substrate. An interferometer system measures a position of the substrate table, and generates a disturbance frequency by optical feedback. A position control system controls the position of the support structure and the substrate table on the basis of the position measurement of the interferometer system. The position control system selects a substrate table speed to prevent a positioning error due to the disturbance frequency.
