融合集成模型与深度学习的机床能耗识别与预测方法
A Method for Identifying and Predicting Energy Consumption of Machine Tools by Combining Integrated Models and Deep Learning
摘要
Abstract
In response to the problems of multi-source influences,high quality feature extraction and selection,complexity and nonlinearity in identification methods for energy consumption proces-ses,a method for identifying and predicting energy consumption of machine tools was proposed by combining integrated models and deep learning.Taking CNC milling as an example,an energy con-sumption model was established based on different cutting periods,and signals were preprocessed by wavelet transform.The preprocessed signals were used to train and predict the energy consumption of the model combining RF and LSTM neural network(RF-LSTM model).Meanwhile,the RF was used to identify the cutting stages and realize the energy consumption classification prediction.The effec-tiveness and superiority of the proposed method were demonstrated through practical cases,and the RF-LSTM model was used to compare with the other four schemes,which verify that this recognition method may accurately predict different operating states and energy consumption of the machine tools.关键词
