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.
