Modeling of Centrifugal Compressor Using RBF Neural Network Based on Cooperative Clustering

In view of the difficulty in establishing a precise centrifugal compressor model in the practical industrial processes, the paper use process data and adopt data-driven modelling method to build up centrifugal compressor model based on RBF neural network; In the light of the difficulty in achieving RBF network's neurons theoretically, the collaborative clustering was adopted. Through an example, it is indicated that collaborative clustering solve the neurons of RBF network well and the constructed model has a good performance in predicting the important performance parameter of centrifugal compressor - pressure ratio, implying that the constructed data-driven model can act as an important tool to serve production process.
