摘　　要：基于Ethernet/IP网络和SERCOS网络,采用罗克韦尔自动化的伺服驱动系统和ControlLogix系统框架构建网络环境下的伺服控制系统。针对伺服系统位置控制的技术要求,对伺服系统建模分析;使用罗克韦尔自动化的运动控制器研究设计出提高控制精度的位置自适应PI控制器。实验结果表明,此控制器解决了常规PI控制器各个参数在系统运行过程中的矛盾问题,提高了机械系统的定位精度。该方案简单可靠,且易于工程实现,可以在相关的运动控制领域中推广应用。The servo system in network environment is established by using Rockwell Automation＇s servo drive system and ControlLogix system based on Ethernet/IP and SERCOS. To the engineering requirment of the position control of servo system, the modelling problem is analyzed. The position adaptive controller is designed by using Rockwell Automation＇s motion controller to meet the requirement of the position control of servo system. The experimental result shows that the controller can solve the contradiction problem of general PI controller, and the location accuracy of the mechanical system is improved. The proposed scheme is reliable and easy to be realized in the field of motion control application.
