Abstract

The invention relates to an acceleration and deceleration control method aiming at high-speed locating motion of paper-pushing device of paper cutter. When the displacement of controlled moving object is larger acceleration and deceleration control with parabola S-shape is adopted. The parabola S-shape is divided into adding acceleration segment (T1), linear acceleration segment (T2), reducing acceleration segment (T3), uniform speed segment (T4), adding deceleration segment (T5), linear deceleration segment (T6) and reducing deceleration segment (T7). Speed control curves of all adjacent segments are connected smoothly. When the displacement of controlled moving object is smaller half-sine acceleration and deceleration control is adopted. The invention selects acceleration and deceleration control strategy according to displacement of controlled moving object. Quick accurate location of paper-pushing device can be realized in ranges of different displacements. At the same time the acceleration impact in high-speed locating process of paper-pushing device of paper cutter can be eliminated completely or decreased obviously. Calculation is simple and it is favor of improving calculating speed of NC system.

Description

technical field [0001] The invention relates to an acceleration and deceleration control method for high-speed positioning moving objects, in particular to an acceleration and deceleration control method for fast-paced point motion of a paper pusher of a numerically controlled paper cutter in high-speed positioning motion. Background technique [0002] After entering this century, the printing industry has developed rapidly, and the paper cutter industry, which is an important equipment for post-press processing, has also gradually grown. At present, my country's paper cutter manufacturers have grown to dozens, and people have higher and higher requirements for the positioning accuracy and speed of the numerical control system of paper cutters. The movement of the paper pusher of the paper cutter is mostly fast point movement, the speed is often much higher than that of the contour control, and the distance of the movement is different, so the numerical control system of the...
