Profile Generation Algorithm and Implementation for High Accuracy Motion

A novel method of third-order motion-to-motion profile planning based on expert system and its reasoning mechanism and precision control strategies are studied in this paper. The algorithm of profile planning with time-optimality is presented. The profile shape of the acceleration is predetermined by using the expert system established. An integer data integral strategy and a roundness compensation strategy based on a correcting factor are proposed to compensate accuracy losses in discrete time implementation. Experimental results demonstrate the effectiveness of the proposed methods.
