Subspace method aided data-driven design of fault detection and isolation systems
TL;DR: In this paper, the authors deal with data-driven design of fault detection and isolation (FDI) systems and identify a primary form of residual generators, instead of the process model, directly from test data and, based on it, design advanced FDI systems.

Statistical process monitoring as a big data analytics tool for smart manufacturing
Q. Peter He,Jin Wang +1 more
TL;DR: A roadmap of statistical process monitoring (SPM) is presented and it is suggested that process characteristics or feature based SPM is a promising route for next generation SPM and could play a significant role in smart manufacturing.

Optimized Design of Parity Relation-Based Residual Generator for Fault Detection: Data-Driven Approaches
TL;DR: Novel approaches are proposed to derive the parity vectors that construct optimized residual generators for linear and nonlinear systems and can significantly improve the sensitivity to small faults, and thus, the fault detection rate is improved compared with the traditional nonoptimized approach.

Analytical redundancy and the design of robust failure detection systems
E. Chow,Alan S. Willsky +1 more
TL;DR: In this article, a robust failure detection and identification (FDI) process is viewed as consisting of two stages: residual generation and decision making, and it is argued that a robust FDI system can be achieved by designing a robust residual generation process.

Closed-loop identification revisited
Urban Forssell,Lennart Ljung +1 more
TL;DR: A new projection approach to closed-loop identification with the advantage of allowing approximation of the open-loop dynamics in a given, and user-chosen frequency domain norm, even in the case of an unknown, nonlinear regulator.
