Slide position intelligent learning control of mechanical press

A new iterative learning control strategy based on the expert knowledge used in the slide of mechanical press is proposed. The slide can be stopped on a accurate position at any point of the slide travel. The proposed strategy is more efficient and accurate than the tiny step operation method. A new computer control system is developed for the mechanical press. It is shown that a lot of experimental results using the new control strategy on press JH23-63 is highly accurate and efficient.
