压铸生产线双电机同步控制轨道车方式仿真

Simulation of synchronous control to railway vehicle for double-motor in production line of pressure cast steel

针对压力铸钢生产线中轨道车同步控制问题,对双电机同步控制系统进行了Simulink仿真。将异步电机作为牵引电机,通过对轨道车控制系统中常用的双电机同步控制方式的分析比较,分别对双电机主从控制、并行控制和交叉耦合控制进行了建模与仿真,仿真结果验证了采用交叉耦合控制的轨道车具有良好的跟随性,能够保证压铸的生产效率。

For the problem of synchronous control railway vehicle in the production line of pressure cast steel, double-motor synchronization control system is studied by Simulink. The three common double-motor sychronons control methods （master-slave control, parallel control and cross-coupling control）were selected to be modeled and simulated on the basic of a synchronous motor acted as a traction motor. The results verify that the railway vehicles controlled by the cross-coupling control is the best to follow and can ensure the production efficiency of pressure cast steel.
