Abstract:
1. A computing system for controlling movement of an object on a machine, the object comprising a working point, the system comprising: a setting module configured for setting a buffer distance parameter and setting a target position of the working point; an acquisition module configured for acquiring a current position and a current speed of the working point when the working point moves along the machine; a calculation module configured for determining a distance between the current position of the working point and the target position, and determining a buffer distance of the working point according to the buffer distance parameter and the current speed of the working point, wherein the buffer distance equals an arithmetical product of the current speed of the working point and the buffer distance parameter; a determination module configured for determining if the buffer distance exceeds or equals the distance between the current position of the working point and the target position; wherein the acquisition module is also configured for determining an instantaneous speed of the working point if the buffer distance exceeds or equals the distance between the current position of the working point and the target position; a control module configured for determining a decay speed based on the buffer distance parameter, the instantaneous speed, and the distance between the current position of the working point and the target position, and for controlling a speed according to the decay speed until the working point reaches the target position, wherein the decay speed is determined according to a mathematical formula of V =V a memory system for storing the buffer distance parameter and the target position of the working point; at least one processor for executing the setting module, the acquisition module, the calculation module, the determination module, and the control module.
