摘　　要：The quality prediction of tube hollow model based on the variance staged multiway partial least square (MPLS) method was proposed.The key aspects of staged decomposition of the productive data,calculation of the variance value,modeling,and on-lined prediction in the variance-staged MPLS method were introduced.Based on the model,iterative optimal control method was used for quality control of tube hollow.The experimental results show that the obvious benefits of this method are low maintenance cost,good real time function,high reliability precision,and practical application to on-line prediction and optimization on the quality of tube hollow.The quality prediction of tube hollow model based on the variance staged multiway partial least square （MPLS） method was proposed.

Based on the model, iterative optimal control method was used for quality control of tube hollow. The experimental results show that the obvious benefits of this method are low maintenance cost, good real time function, high reliability precision, and practical application to on-line prediction and optimization on the quality of tube hollow.
