A High Precision Synchronizing Control System for Biaxial Positioning Tables

In this paper, a control system is designed that synchronizes the motions of biaxial positioning tables. The control system consists of nonlinear feedback laws of the displacements and the velocities of the table along its axes. The designed control system successfully generates desired contours on the workpiece by synchronizing the motions of the biaxial table along its axes, and compensates for the effects of parametric uncertainty and disturbance to the system.
