摘　　要：针对工业运动控制中多轴同步性问题,设计了一款基于EtherCAT实时以太网的伺服运动控制系统。系统主站根据EtherCAT通信原理对从站通信控制器分布式时钟进行操作,使其输出同步信号,实现对两轴实验平台运动的同步控制。实验结果表明,该系统具有良好的稳定性和同步性。Aiming at the multi -axis synchronization problem of industrial motion control, a design of servo motion control system based on the real-time Ethernet EtherCAT is presented. According to the theory of EtherCAT communication ,the master station operates the distributed clocks of EtherCAT slave controller to output the synchronization signal to achieve the synchronized motion control of the two-axis experimental platform. The experimental results show that the system has good stability and synchronicity.
