To solve the problem that the data of new plasticising process of single-base gun propellant is not enough to build an accurate model for predicting the product quality, a modified multiway joint-Y partial least squares (MMJY-PLS) transfer model for final quality prediction in the plasticising process is proposed. Firstly, the modelling efficiency of the new plasticising process is improved by transfer learning using the plasticising process data of similar source domain. Secondly, the internal structure of the JY-PLS transfer model is improved so that the regression coefficients of the source and the target domain are no longer the same, and the prediction performance of the model is further improved. Finally, the MMJY-PLS process transfer model was applied to predict the final quality index in the plasticising process of two single-base gun propellant products, and the experimental results show its effectiveness.
