Abstract

A high level of process monitoring is necessary for the safety and product quality of an electric magnesium melting furnace. However, plant upgrading, such as the addition of cameras, has brought challenges to the traditional monitoring methods although more information about furnace conditions can be obtained. This is because graphic data and sensor data are completely different in structure and calculation. Therefore, a compatible collaborative modeling and fault detection method is proposed in this paper. Firstly, the system and residual subspace of data are obtained by minimizing the statistical distance of data from different information sources through collaborative modeling. Then the weighted information fusion of subspace data is carried out to develop and integrate a new hierarchical fault detection and alarm scheme. Finally, the feasibility and effectiveness of the proposed method are verified by the real data of magnesia smelting process.

基于协同建模的电熔镁炉故障检测

高水平的工艺监控是保证电镁炉生产安全和产品质量的必要条件。然而，工厂升级，如增加摄像头，给传统的监测方法带来了挑战，尽管可以获得更多的炉况信息。这是因为图形数据和传感器数据在结构和计算上完全不同。为此，本文提出了一种兼容的协同建模与故障检测方法。首先，通过协作建模，最小化不同信息源数据的统计距离，得到系统和数据的残差子空间；然后对子空间数据进行加权信息融合，开发并集成了一种新的分层故障检测与报警方案。最后，通过氧化镁冶炼过程的实际数据验证了该方法的可行性和有效性。

期刊介绍： Control Engineering Practice strives to meet the needs of industrial practitioners and industrially related academics and researchers. It publishes papers which illustrate the direct application of control theory and its supporting tools in all possible areas of automation. As a result, the journal only contains papers which can be considered to have made significant contributions to the application of advanced control techniques. It is normally expected that practical results should be included, but where simulation only studies are available, it is necessary to demonstrate that the simulation model is representative of a genuine application. Strictly theoretical papers will find a more appropriate home in Control Engineering Practice''s sister publication, Automatica. It is also expected that papers are innovative with respect to the state of the art and are sufficiently detailed for a reader to be able to duplicate the main results of the paper (supplementary material, including datasets, tables, code and any relevant interactive material can be made available and downloaded from the website). The benefits of the presented methods must be made very clear and the new techniques must be compared and contrasted with results obtained using existing methods. Moreover, a thorough analysis of failures that may happen in the design process and implementation can also be part of the paper. The scope of Control Engineering Practice matches the activities of IFAC. Papers demonstrating the contribution of automation and control in improving the performance, quality, productivity, sustainability, resource and energy efficiency, and the manageability of systems and processes for the benefit of mankind and are relevant to industrial practitioners are most welcome.
