Traditional computer engraving machine deceleration control algorithm

by：Transon 2020-07-25

Computer engraving machine most of the traditional linear deceleration control is based on the trapezoidal or triangular, divides into the movement process simple add, subtract, uniform three process. For a longer line adopt from starting speed to accelerate, after reaching motor allows the maximum speed of uniform, finally slowed to starting speed, for short line segment, only two acceleration and deceleration process. Below in a single shaft as an example this paper introduces the traditional linear deceleration process, ( a) For the long period of deceleration process, b) For short period of deceleration process, x ( i) For after I period of line displacement, where V0 for starting speed.
introduce a simplified method has the merits of the traditional computer engraving machine is a simple calculation, machine fast reaction, not easily get out of step in the linear motion. Defect is for short term period of fitting curve, spend a lot of time in deceleration stepper motor, reducing the efficiency of computer engraving machine.
