Research on the Interpolation Processing Based on the Acceleration Control Information

Abstract

In order to further improve the accuracy of the trajectory control and reduce the contour error, a novel method is proposed. This method uses a slight arc segment to approximate the trace curve between discrete points based on the acceleration information. The acceleration information of every discrete point will be provided to the servo control system of each axis to execute the acceleration feed forward control, thus realize the arc connection between the interpolation points. Finally, the simulation experiment results verify the effectiveness of the proposed algorithm.
