N2 - In this paper, a novel and precise contouring control strategy is designed based on the model of linear motor direct drive for X-Y table. This control strategy consists of two key parts-a precise Newton-based contouring error estimation (NCEE) and a chattering-free discrete-time sliding mode contouring error control (CDSM-CEC), and the details of designing the control strategy are stated. Specifically, NCEE is obtained according to the Newton-based extremum seeking, which is a dynamic method having rather good performance even when highly-curved reference contouring occurs. As for CDSM-CEC, it is developed from equivalent-control based sliding mode control, to reduce the ubiquitous chattering phenomenon in discrete-time sliding mode control. Experiments to track a circular contouring are implemented with comparison to prove the precise performance of the proposed contouring control strategy.
