Simulation and Analysis of Electromechanical Integration Control in High Speed Trains

A simulation model of electromechanical integration control is built based on the theory of direct torque control（DTC） and vehicle system dynamics. The simulation model combines the advantages of circular flux control and hexagon flux control, and vehicle me- chanical transmission system is also considered. The simulation is applied to the High Speed Train and analyses the states of electrical and mechanical parts in the case of traction, uniform motion and braking. During the simulation, the starting resistance and running re- sistance are considered. The simulation results show that, the system has excellent static and dynamic performances and combines the electrical part and mechanical part fully together and realizes the optimal control of traction drive system in High Speed Trains. The method can be used for the further research of electromechanical integration.
