说明：  变分模态分解的整体框架是变分问题，使得每个模态的估计带宽之和最小，其中假设每个“模态”是具有不同中心频率的有限带宽，为解决这一变分问题，采用了交替方向乘子法，不断更新各模态及其中心频率，逐步将各模态解调到相应的基频带，最终各个模态即相应的中心频率被一同提取出来(The whole framework of variational mode decomposition is variational problem, which makes the sum of the estimated bandwidth of each mode minimum. It is assumed that each "mode" is a finite bandwidth with different center frequencies. To solve this variational problem, the alternating direction multiplier method is used to update each mode and its center frequency continuously, demodulate each mode to the corresponding fundamental frequency band step by step, and finally each mode is called the first mode The corresponding center frequencies are extracted together)
