摘要

为了实现数据驱动技术在工业中的实际应用，开发了以蒸馏塔作为被控对象的半实物仿真系统，将数据驱动方法应用到流程工业半实物仿真系统.针对动态主元分析方法存在的计算负荷大，计算效率低的问题，提出了一种改进动态主元分析方法，利用不可区分度和交叉程度去除众多变量中的不相关变量或相关度较小的变量，减少数据量.针对系统中的典型故障，数据驱动方法能够检测出半实物仿真系统中的异常，而且与传统动态主元分析比较，改进算法降低漏报率和误报率，提高诊断可靠性，并且能及时检测出生产过程的微小故障.

Abstract

In order to apply the data-driven technology in industry field

with the distillation column as one of the controlled objects

the hardware-in-the-loop simulation system is developed

and the data driven methods are applied to the process industry hardware-in-the-loop simulation system.Aiming at the huge computation and low efficiency of the dynamic principal component analysis method

an improved dynamic principal component analysis method is proposed

which remove the irrelevant variables or low relevant variables

reduce the amount of data

and improve the diagnostic efficiency by indiscernibility and the cross-degree.For the typical faults of the systems

the application result shows that the data-driven methods can detect the fault of hardware-in-the-loop simulation system

and compared with the traditional dynamic principal component

the simulation results show that the proposed method is more reliable with lower missing rate

and lower false rate

and in addition

it can detect the small process faults timely.
