In driving a movable body in a target direction, a force in another direction, which may act on the movable body, is reduced. A system includes a current amplifier, which drives X1 and X2 electromagnets (a first actuator) for aligning the movable body in the X direction, a system including a current amplifier, which drives Y1 and Y2 electromagnets (a second actuator) for aligning the movable body in the Y direction, a subordinate direction component correction unit, which reduces a force in the Y direction acting on the movable body when driving the movable body in the X direction by the first actuator, and a subordinate direction component correction unit, which reduces a force in the X direction acting on the movable body when driving the movable body in the Y direction by the second actuator.
