A VMD-EWT-LSTM-based multi-step prediction approach for shield tunneling machine cutterhead torque

作者:

Highlights:

• We present a VMD-EWT-LSTM-based multi-step prediction method for cutterhead torque.

• VMD and EWT decomposes original input sequence into relatively simple subsequences.

• The appropriate mode quantity K of VMD could be determined adaptively.

• It only deals with one input reducing calculation time and improving efficiency.

• Its five-step average accuracy reaches 97.7%, 97.2%, 96.9%, 96.7% and 96.3%.
