Analysis of Multi-axis Synchronized Motion Systems Based on Virtual Line-shaft Control

虚轴法控制方式在主从同步控制方案的基础上,引入主从控制方式缺少的反馈环节,可以有效的解决同步控制中各个运动轴ji的ng运动同步性等问题。文章在比较几种常用同步运动控制方式的基础上,主要研究了如何将虚轴法运用在多轴电机同步运动控制系统中,并建立了相应的多电机同步运动控制系统仿真模型,最后并与主从同步运动控制方式的效果进行了比较与分析。仿真及实验结果证明了此模型的有效性。

Loading into the feedback not exist in the Master-slave control mode, based on the master-slave synchronization control system, the Virtual Line-Shaft control method（VLSM） can effectively solve the synchronization problems of every axis in synchronous control system. Based on comparing the several commonly used synchronous control method, the research mainly solved how to use the VLSM in mul- ti-motor motion synchronization control system, and set up a simulation model of the multi-motor synchronous control system. At last, the analysis and comparison with the master-slave motion synchronization method was showed that the VLSM had the advantage. Simulation and experiment results indicate that this model is effectual.
