摘要:

The traditional S type acceleration/ deceleration algorithm in CNC system is not suitable for high-speed motion due to the mutation of jerk. A flexible acceleration/deceleration algorithm suitable for high-speed motion system was introduced, in which the velocity, acceleration, jerk and displacement were all consecutive and the values of jerk at the beginning and end point were zero. Compared with traditional trigonometric function algorithms, the proposed algorithm was more flexible and could give full play to the maximum acceleration performance of CNC machine tool. Displacement adaptation method and interval discrimination method were proposed to plan the acceleration and deceleration mode. The interval discrimination method could quickly find the interval of velocity value by a few simple calculations. The acceleration and deceleration curve parameters could be obtained by solving quadratic equation only once, which ensured the high efficiency. This algorithm was analyzed and discussed with MATLAB. Through experiment, the smooth continuous acceleration and velocity curve were obtained, which proved the accuracy and the feasibility of the proposed algorithm. © 2019, Editorial Department of CIMS.
