试管的优秀预言空模型基于变化上演了 multiway 部分最少的平方(MPLS ) 方法被建议。生产数据的上演分解的关键方面，变化价值的计算，建模，并且在上演变化的 MPLS 方法的 on-lined 预言被介绍。基于模型，反复的最佳的控制方法被用于试管的质量控制空。到试管的质量上的联机预言和优化的这个方法的明显的好处是花费的低维护的试验性的结果表演，好实时函数，高可靠性精确，和实际申请凹陷。

英文摘要：

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.
