Design of Position Adaptive Controller for Servo System in Network Environment

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.
