The invention relates to a maglev train suspension control system based on Ethernet communication. The maglev train suspension control system comprises a vehicle-mounted computer, an Ethernet gateway, a plurality of network nodes and a plurality of suspension electromagnets. The vehicle-mounted computer is connected with the network node through the Ethernet gateway, and the suspension electromagnet is controlled by the network node; the network node comprises an EtherCAT master station and (n + m + k) slave stations, each slave station comprises n suspension control system cooperative controllers, m suspension sensors and k integrated choppers, Ethernet communication is adopted between the slave stations and between the slave stations and the EtherCAT master station, and series connection is achieved through an EtherCAT bus. Cooperative control among a plurality of control loops and information mutual transmission among the suspension controllers are realized, meanwhile, the control current of the suspension electromagnet is calculated by combining a feedback control strategy with a cross coupling control algorithm, and the anti-interference performance of suspension control is improved. Compared with the prior art, the system has the advantages of high transmission speed, high anti-interference performance, low cost and the like.
