Control and communication of a multi-motor system based on LAN

This paper establishes a multi-motor control system based on the local area network. It introduces the control strategy and the master-slave network structure. It analyzes both the advantage and disadvantage of the traditional communication modes RS-422 and CAN. And based on the analysis, the paper puts forward a full-duplex communication method which combines the advantages of both RS-422 and CAN to achieve the network control for the multi-motor system.
