A control device configured to determine a primary first drive signal, based on a first error signal representing a difference between desired and measured positions of a first body, for driving a positioner driving the first body; determine a primary second drive signal, based on a second error signal representing a difference between desired and measured positions of a second body, for driving a positioner driving the second body; determine, based on the second error signal, a secondary first drive signal for driving the first body positioner; determine, based on the first error signal, a secondary second drive signal for driving the second body positioner; combine the primary and secondary first drive signals and combine the primary and secondary second drive signals; and output the combined first and second drive signals to the respective positioning devices. |
