功率谱密度计算程序，可以用于计算时域信号的功率谱密度。(The power spectral density calculation procedures can be used to calculate the power spectral density of the time-domain signal.)

采用music算法来用于进行DOA估计，可以达到很高的识别精度(MUSIC algorithm is used for DOA estimation, which can achieve very high recognition accuracy)

分别采用滞环电流和电压空间矢量技术进行PWM调制,波形完美(Respectively using hysteresis current and voltage space vector PWM modulation)

说明：  function [ret,x0,str,ts,xts]=s1(t,x,u,flag) s1 is the M-file description of the SIMULINK system named s1. The block-diagram can be displayed by typing: s1. SYS=s1(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS. Setting FLAG=1 causes s1 to return state derivatives, FLAG=2 discrete states, FLAG=3 system outputs and FLAG=4 next sample time.
