中文说明：分析了该信号的时域、频域、倒谱，循环谱等,通过虚拟阵元进行DOA估计，计算加权加速度,数据模型归一化，模态振动，IMC-PID是利用内模控制原理来对PID参数进行计算，外文资料里面的源代码。
English Description：
Analysis of the signal in time domain and frequency domain, cepstrum, cyclic spectrum, through virtual array for DOA estimation, weighted acceleration calculation, data normalization model, vibration modal, IMC-PID is by using the internal model control principle of PID parameters are calculated and foreign material inside the source code.
