Description: VMD (variable mode decomposition) is an adaptive and non recursive method for modal variation and signal processing. This technique has the advantage of determining the number of mode decomposition. Its self adaptability is that the number of mode decomposition of the given sequence can be determined according to the actual situation. In the subsequent search and solution process, it can adaptively match the optimal central frequency and finite bandwidth of each mode, and realize the effective separation of intrinsic mode components (IMF), frequency domain division of signals, and then get the Given the effective decomposition component of the signal, the optimal solution of the variational problem is obtained.
