摘要:
A positioning method and positioning system wherein a driving device, for moving a movable table on a rough-motion stage by a small amount, is alternately controlled through a pair of switchable control systems. The amounts by which the table is driven are initially adjusted to the same amounts by the pair of control systems when the paired control systems are switched.
