Abstract

The invention provides a flexible acceleration and deceleration control method and system for a machine station. The method comprises steps that when the running distance is greater than or equal to the sum of the acceleration running distance and the decelerating running distance, the first actual acceleration and the first actual deceleration are calculated through a first mathematical model; when the first actual acceleration and the first actual deceleration are both smaller than or equal to the allowable maximum acceleration, the first running trajectory of a driving shaft of the machinestation is planned according to the running distance, the starting speed, the ending speed, the acceleration time, the deceleration time, the given maximum running speed, the allowable acceleration maximum value and the allowable speed maximum value, and the driving shaft is controlled for running based on the first running trajectory. The method is advantaged in that the operation process is simple, the amount of calculation is small, the load of a server is reduced, work efficiency of the server is improved, and safety, applicability and practicality of the machine station are improved.

Description

technical field [0001] The invention belongs to the field of machine control, and more specifically relates to a flexible acceleration and deceleration control method of a machine. Background technique [0002] Acceleration and deceleration control has always been one of the core technologies of the motion control system, which determines the motion accuracy and operating efficiency of the machine. The traditional acceleration and deceleration methods include trapezoidal acceleration and deceleration and exponential acceleration and deceleration. Due to sudden changes in acceleration, there is a flexible impact. It is only suitable for areas with low motion precision and speed. Flexible acceleration and deceleration control methods include S-type acceleration and deceleration, trigonometric function acceleration and deceleration and polynomial acceleration and deceleration. Because the latter two calculation processes are too complicated, high-speed and high-precision machi...
