The Network-Based Implement Of DCS And Analysis Of Propulsion System Of Maglev Circle Line

As high-speed maglev train has its advantage comparing to traditional train system, it is the orientation of high-speed train research. The high speed of maglev train requires good performance of operation control system (OCS) and propulsion control system (PCS) to assure its safety. In the process of localization of maglev train, implement of network control of OCS, as well as the strategy of propulsion and power supply, are of significance.Based on the circle experimental maglev line of Zhejiang Maglev experiment platform, the thesis began with the introduction of the construction and function of OCS, especially the Decentralized Control System (DCS). Then the solution and realization for DCS network control were proposed. Next, the applications of PROFIBUS and Industrial Ethernet in DCS were discussed in details.For the further research on PCS, the simulation model of the PCS in TR08 Maglev train was constructed then. The control strategy which chose rotor magnetic flux oriented vector control was determined at first, then the model of PCS with MATLAB/SIMULINK was constructed, which validity was proved by a representative route model. At last, the study on dynamics characteristic of PCS in different situation was also included.
