ABSTRACT:
In a lithographic projection apparatus, modified control of a moveable component within the apparatus is provided to improve control of the position and velocity of a point on the component that is set apart from the center of mass of the component. The force required to provide the center of mass of the component with the acceleration required for the point on the component is determined. The force in a given direction is corrected by an amount proportional to the product of the velocity of the point in an orthogonal direction and the angular velocity about an axis perpendicular to the two orthogonal directions.
