摘要:多模态复杂过程的多变量、多工序、变量时变性以及模态转换时间不确定等多种原因,导致面向多模态生产过程的监测问题十分复杂.对此,基于高斯混合模型的监测方法,结合定性知识和定量知识,解决了多模态过程监测中离线数据模态划分、稳定模态和过渡模态的监测模型建立以及在线数据的模态识别等关键问题,最终实现了对多模态过程的监测.
Considering the process high dimensionality, multi-operation, time-variant characteristics, and unknown mode duration, it is challenging to conduct the statistical analysis and online monitoring for multi-mode processes. The process monitoring model based on the Gaussian mixture model(GMM) combining quantitative with qualitative information solves several key points, such as mode classification of offline data, model building for stable modes and transitional modes, and mode identification of online data. Process monitoring for multi-mode processes is realized by using the proposed method.
