电力牵引电机控制，设计的目的是用MatLab得到系统的状态空间模型，计算系统的传递函数。并预测系统的阶跃响应，并判断系统是否能控和能观。(Electric traction motor control, is designed to be used MatLab system state space model to calculate the system transfer function. And predict the system step response and determine whether the system is able to control and observability.)
