Abstract：Con tact motion exists in PMLSM table drive systems, so among the sliding surface of the table there must be nonlinear friction. This paper presents a disturbance-observer compensating the nonlinear friction. Using the observer, the precise velocity/position control can be achieved, and zero velocity interval at the velocity reversal does not exist.
