Abstract: In order to study the effect of network delay and methods of delay compensation in the networked closed loop control systems,controller area network(CAN) bus is applied to servo control system to constitute a distributed control system with bus mode network topology.An experiment platform for the organization and implementation of motion control system is introduced and a controller is designed to solve the actual problems of networked control system.Experiments are performed to testify the feasibility of the scheme presented in the paper.
