一维功率谱密度计算程序，可以选择是否加窗，加那种窗(1D power spectral density caculation routin base on fft )

wt8871的源代码，应用于车载仪器仪表或卫星导航等方面(wt8871 for application TV、GPS&outmeetor)

采用传递函数的转速、电流双闭环直渡调速系统的仿真模型(Using the transfer function of the speed of the current double closed loop the straight crossing speed control system simulation model)

DC dynamic braking is obtained when the stator of an induction motor running at a speed is connected to a dc supply.dc current flowing through the stator produces a stationary magnetic field.Motion of rotor in this field induces voltage in the rotor winding.Machine therefore works as a generator.Generated energy is dissipated in the rotor circuit resistance,thus giving dynamic braking.

说明：  异步电机的SVPWM闭环的DTCsimulink文件，可以闭环正常运行，波形还行(Asynchronous motor SVPWM closed-loop dtcsimulink file, can be closed-loop normal operation, waveform is OK)
