Abstract
The contour control of industrial mechatronics servo system have been implimented in cutting process, sealing, polishing and boundeering. In recent years, the control performance with high precision is requied from working environments and quality improvement. A method for precise contour control of mechatronic servo system with master-slave axes was proposed by use of the synchronous position control technique. Robustness of the proposed method for the modelling error was analysed theoretically. The proposed method was evaluated by use an experiment of XY table and showed satisfactory contour control performances.
