永磁同步电机变频调速系统仿真，利用matlab仿真不报错(Permanent magnet synchronous motor speed regulation system simulation using matlab simulation without error)

供做算法研究人员参考，表示出两帧图像间各个像素点的相对情况，包括最后计算压缩图像的峰值信噪比和压缩效果的源码。( Algorithm for researchers to do reference, Between two images showing the relative circumstances of each pixel, Including the final calculation of the compressed image peak signal to noise ratio and compression of the source.)

首先定义累计量函数，然后通过调用四阶累计量来实现有色噪声中谐波恢复，但有个缺点是信号源估计在实际应用时应有所改进！(First, the definition of cumulant function, and then by calling the fourth-order cumulant to achieve the harmonic retrieval in colored noise, but one drawback is that the signal source is estimated that in practical applications should be improved!)

说明：  Welch法功率谱密度 Psd自功率谱 是用改进的平均周期图法来求随机信号的自功率谱估计 采用信号重叠分段，加窗函数和fft算法等计算一个信号的自功率谱估计（PSD）
