This paper presents a mode switching feedback (FB) compensation methodology based on rolling friction models for the fast and precise positioning of table drive systems. Rolling friction in the table drive mechanisms behaves as a nonlinear elastic component in the micro displacement region and deteriorates the position settling performance with slow(More)
