N2 - This paper puts forward the iterative learning control (ILC) function for the existing CNC systems, aiming at the large number of actual need of single-piece repetitive processing tasks. The previous processing error is superimposed on the next processing, with use of the last processing of the control, and gradually improves the processing accuracy, thereby improving the product yield. In the iterative learning processes, the tracking error decreases in the first few cycles and increases to diverge. In order to solve the aforementioned problem, the zero-phase filter is designed to improve this situation. Simulations and hardware in the loop simulation on XY-table demonstrate that the aforementioned problem can be reduced effectively used the proposed method.
