This technique has the advantage that the number of modal decompositions can be determined. Its adaptability manifests itself in determining the number of modal decompositions for a given sequence according to the actual situation. The subsequent search and solution process can adaptively match the number of each modal decomposition. It has the best center frequency and limited bandwidth, and can achieve effective separation of inherent modal components (IMF), frequency domain division of signals, and then obtain effective decomposition components of a given signal, and finally obtain the optimal solution of the variational problem.)
