On-line detection of abrupt changes in the carrier-phase measurements of GPS
Stelios P. Mertikas,Chris Rizos +1 more
TL;DR: The statistical technique known as the cumulative-sum test is described for the detection of abrupt changes in the GPS carrier-phase measurements and designed algorithms to detect failures or changes of small magnitude are designed in order to monitor and control the quality of GPS measurements for critical real-time and/or deformation applications.

Visual dynamic model based on self-organizing maps for supervision and fault detection in industrial processes
TL;DR: An approach based on the self-organizing maps to model the dynamics of multivariable processes is presented and a new method of residual computation for fault detection and identification that uses the dynamic information provided by the model of transitions is proposed.

Fault Reconstruction Based on Sliding Mode Observer for Nonlinear Systems
Jing He,Changfan Zhang +1 more
TL;DR: In this article, a fault reconstruction scheme for a class of nonlinear systems involving unknown input disturbances is presented, where the disturbances and faults of the system are fully decoupled, and the design of a sliding mode state observer makes the most genuine reconstruction realizable.

Fault detection by using the innovation signal: application to an exothermic reaction
TL;DR: In this article, an extended Kalman filter (EKF) was applied to a nonlinear system such as stirred reactors in the presence of exothermic chemical reactions to reveal any drift from the normal behavior of the process.

Fault detection and safety in closed-loop artificial pancreas systems.
TL;DR: Techniques for fault detection, safety analyses, and remote monitoring techniques that have been applied in other industries and applications, such as chemical process plants and commercial aircraft, are discussed and placed in the context of a closed-loop artificial pancreas.

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.
A survey of design methods for failure detection in dynamic systems
TL;DR: A number of methods for detecting abrupt changes (such as failures) in stochastic dynamical systems are surveyed in this paper, where tradeoffs in complexity versus performance are discussed, ranging from the design of specific failure-sensitive filters, to the use of statistical tests on filter innovations, and the development of jump process formulations.
