Abstract:
1. A driving apparatus for moving an object, said apparatus comprising: a first actuator which drives the object in X and Y directions; a second actuator which drives a reaction force counter which receives a reaction force generated when said first actuator drives the object; and a controller which controls said second actuator on the basis of X- and Y-direction positions of the object and X- and Y-direction accelerations of the object so as to cancel, by said second actuator, the reaction force to be received by said reaction force counter when the object is driven by said first actuator, wherein said controller calculates X- and Y-direction reaction forces and a rotation-direction reaction force, which are to be received by said reaction force counter when the object is driven by said first actuator, and generates a profile to drive said reaction force counter on the basis of the X- and Y-direction reaction forces and the rotation-direction reaction force.
