Research on Fast Algorithm of 3-axis Simultaneous-motioned Step Motor Acceleration/ Deceleration Control

Acceleration/deceleration control is the key technology of CNC, and is significant for improving the precision velocity of CNC. A fast algorithm, dynamic look-up table algorithm, of 3-axis simultaneous-motioned step motor acceleration/deceleration control is presented, which integrates with??DDA interpolation algorithm and can be used for motion control of many acceleration/deceleration control curves with common MCU. The algorithm has many advantages such as speediness, high precision, etc.
