Intelligent Control Method for Acceleration and Deceleration of CNC Machine Tools Based on Attention Mechanism and Position Error
摘要
Abstract
Due to poor intelligence in machine tool processing speed and path control,processing accuracy and workpiece quality are affected.Therefore,an intelligent control method for acceleration and deceleration of CNC machine tools based on attention mechanism and position error is studied.Construct the kinematic model of CNC machine tool,and calculate the theoretical values of the motion frequency of the inner and outer ring structures of CNC machine tools;Using attention mechanism to track the motion trajectory of machine tools and determine the acceleration and deceleration scale coefficients of CNC machine tools;Using the scale coefficient as the control parameter and referring to the motion position nodes of the in-ner and outer ring structures,the time interpolation period during the acceleration and deceleration process is obtained based on the position error;Determine the control variables according to the fuzzy vector transformation rules,and use interpola-tion period inversion to infer the acceleration and deceleration control amount of CNC machine tools,intelligently controlling the acceleration and deceleration process of CNC machine tools.The experimental results show that selecting a stepper motor as the driving power system of a CNC machine tool and controlling the three-phase motion curve supplied by the motor sepa-rately can achieve ideal control effects and ensure the machining accuracy of this type of CNC motor,which has practical val-ue.关键词
