Abstract
The objective of this paper is to provide a status report of the methods and applications of data-driven fault detection and diagnosis to the IFAC Safeprocess community. The scope of the problem is described with reference to the scale and complexity of industrial processes, where multi-level hierarchical optimization and control are a must for efficient operation, but are also prone to hard or soft faults that lead to economic losses. Commonly used multivariate statistical tools are introduced to characterize normal variations and detect abnormal changes. Further diagnosis methods are discussed next, with additional topics for rigorous analysis. An application case is presented, and future challenges and opportunities are speculated with the hope to draw more attention from the Safeprocess community. © 2009 IFAC.
