ABSTRACT:
A structure is provided in which a thrust feed forward structure for operating a structure to be driven without vibration and a control structure which simultaneously compensates for positional deviation caused by the thrust feed forward structure and positional deviation caused by a base displacement are included in a position controlling device (3). Alternatively, a structure is provided in which an acceleration and deceleration process for realizing response of the position of the structure to be driven and base displacement without vibration and a control structure which determines a feed forward amount with respect to a position instruction value after the acceleration and deceleration process are provided to the position controlling device.
