matlab里怎么仿真串励直流电机？

archdevil

在simulink里找了个DC machine的模型，想做串励直流电机的仿真，但仿真不对，看了下DC machine的help，发现只能用作他励直流电机，要怎么改才能作为串励直流电机用呢？

Description

The DC Machine block and the Discrete DC Machine block (also in the Machines library) both implement a separately excited DC machine. The DC Machine block implements a continuous model, and the Discrete DC Machine block implements a discrete model. The following description applies to both blocks.
An access is provided to the field terminals (F+, F-) so that the machine model can be used as a shunt-connected or a series-connected DC machine. The torque applied to the shaft is provided at the Simulink input TL.

直接串起来

直接串起来试过了，仿真结果感觉不对，转速一直很低，

这句话是说这个电机模型只能他励吗？
我用他励电机双闭环已经仿真好了，把这个电机改成串励的，仿真的结果就不对，转速一直很低。
