Abstract

The invention relates to a non-linear process industrial fault prediction and identification method based on compressed sensing and dynamic recurrent online sequential-extreme learning machine (DROS-ELM). According to the high-performance non-linear process industrial fault prediction and identification method, a problem of shortage of the on-line fault prediction and identification during the non-linear production process of the complicated industrial system can be solved. The compressed sensing and the artificial neutral network are applied to the industrial field and thus fault prediction and identification models based on the compressed sensing feature extraction and dynamic feedback OS-ELM neutral network technology is respectively constructed, thereby realizing fault prediction. Therefore, a technical support can be provided for guaranteed safety production, improved production efficiency, and saved production cost of the enterprise.

Description

technical field [0001] The invention relates to the field of industrial control, in particular to a nonlinear process industrial fault prediction and identification method based on compressed sensing and DROS-ELM. Background technique [0002] At present, with the complexity of large-scale industrial system processes and the increasing number of control links and control points, once a safety accident occurs in many major and difficult-to-observe hazards, it will cause huge loss of life and property. [0003] In recent years, accidents caused by system equipment failures have occurred frequently, and fault prediction and identification technology has also attracted the attention of scholars at home and abroad. It has become an urgent need to realize system-wide fault prediction and identification. The fault prediction and identification method needs to judge whether a fault occurs in the system in the future according to the past and current state of the system, and accurate...
