Abstract：To improved contour accuracy of XY table directly driven by two linear motors, a novel control law that combined the velocity vector field and the feedback linearization method is proposed. To plan the contour desired path and transform biaxial coordination control into the velocity control of single axis, constructs velocity field based direction field grid point method. In order to reduce the velocity error directly and eliminate nonlinear dynamics, the state feedback controller is designed. Simulation results show that the proposed scheme can ensure the system has the higher contour accuracy.
