针对VMD算法在处理过程中其IMF分量个数K要预先设置，其设置的值不同

For the VMD algorithm, the number of IMF components K must be set in advance, the value of the setting is different, the final signal processing result will also be different, and the penalty parameter c has a greater impact on the broadband of the modal components. This paper proposes to use PSO The algorithm optimizes the two influencing parameters of the VMD algorithm to select the best influencing parameters.

In view of the VMD algorithm in the process of processing its IMF component number K to be set in advance, its set value is different, the signal final processing results will be different, and the penalty parameter c has a greater impact on the modal component of broadband, this paper proposes to use PSO algorithm to optimize the VMD algorithm's two influence parameters, so as to filter out the best impact parameters.

In the process of VMD algorithm processing, the number of IMF components K should be set in advance, the value of which is different, the final signal processing result will be different, and the penalty parameter C has a great influence on the broadband of modal components. This paper proposes to optimize the two parameters of VMD algorithm by PSO algorithm, so as to select the best parameters.<br>
